The DIY Winter Camping Sleep Pad
Вставка
- Опубліковано 15 жов 2024
- They make Foam pads and self inflating pads for camping and hiking. Some have insulative qualities but none have reflective qualities to reflect back your body heat. Here I try to build and test an idea Ive been thinking about for years.
Helpful Hint > A commenter just told me this same foam can be bought new at home improvement stores as its also used as an under layer for new wood floors.
Thanks for the info .
I Michigan, it’s called Reflectix
•In Michigan
Yes, I've seen it in the UK stores.
Man after my own heart.
All good out doors men own a sewing machine. Would not be with out mine to make one off items.
He sews, he welds he comes up with crazy inventions. Talk about mutlti talented. I'm in awe
LOL! If its a material that can be connected I'll use it!
👍🥳💜Awesomeness.”
IKR? Goals!
@@Reallybigmonkey1 Are you an ISTP, by chance?
@@wmluna381 I have no idea what that is
Being from an area of Texas where hiking for days out in the woods is not available, I have camped for several days on the Colorado River and large tanks( ponds for you non Texans) while fishing. I sewed many bags to carry my "stuff" like plastic boxes filled with lures that would fit my web belt which carried my GI canteen and .22 pistol. I made pouches to carry boxes of ammo as well. It was so much fun building them using the trial and error method. That is what I like about your videos as you love to design and sew items to help you out in the woods. Thanks for sharing. A word of advice for improving your sleeping pad, make one side using fleece which will also help you stay warm. Keep the videos coming, Dave.
Sounds good, and a lot like me! I absolutely love making stuff
Everyone else has said everything that I would have, except for one thing: I've always admired the fact that you do your own sewing on these projects. I know a lotta guys who'd refuse to learn to sew for a variety of reasons, but you just dove right in and actually took the time to explain locking in the stitch to the viewers. It's such a minor thing, but I love it. (Also, I love your running gag of Camo Because It's Cool.)
I learned to sew as a kid. My mom refused to make my Halloween/theater costumes for me, but was willing to HELP me make them. By the time I was a teen, I was taking in the waists on my jeans (the curse of tall and thin guys) by myself. I've found that having a bit of sewing knowledge helps you in so many interesting and cool ways, especially if you're doing things on a budget.
Very well said! Funny thing about me sewing, With me being a welder I often ruin clothes and had to sew up rips and burns by hand. I got sick of it and learned to sew with a machine. I then started sewing bags for cook kits, then fire kits. Next came sleeping bag covers then shelters and on and on! It is a great way of saving money but the best part? If you cant buy what you want, then make it! Thanks for the comment and thanks for watching
Sewing is really relaxing and having a standard and heavy duty machine for making canvass tents and other gear has saved a lot of money . I still have a very old foot powered treadle sewing machine which was found in a garbage dump and totally reconditioned and it works great . ATB
Every feller should his way aroud a sewing machine,hey my third wife taught me!! I do alot of my own sewing projects! Alsome video David as you useally do
@@Reallybigmonkey1 Many times I think the homemade sewn items are sturdier? You can be sure of the quality of the seams when you do it yourself. Another great video: make it yourself and not trying to sell the expensive stuff which many of us can't afford. Thanks for all your great information!
It’s not a sewing machine, it’s a thread injector.
Great idea Dave. I am a hammock camper and the commercial underquilt options are really expensive. It would appear your idea could be applied to a hammock very easily. Your idea is impervious to the wind and not at all subject to compression. You have a real winner there for both ground and hammock applications.
Thanks Jim, I'm glad you liked it. Man you have stirred an idea in my head now! Since I sewed the bag, then why not sew some tie ons for a hammock so it doesn't move around? Thanks for watching
Jim Ferguson - Might sound weird , but I use a military body bag for a comfortable and FLAT hammock - sleeping bag cover . Stuff if full of leaves and it gets you off the ground and makes a passable mattress . Put gear in it and use for a flotation device for crossing a river ... or as I did in Canada , used it to get to an island in a lake . Can be used as an improvised back pack and also good as a litter for carrying people in an SAR / search and rescue scenario . Drag it over snow with firewood . ATB !
Nav Star Great idea, I told Dave a while back about how the body bags can be used as a bivi bag, a pole bed, a hammock, improvise a camp chair, a bed roll, a pack and more. Dave said he didn’t know where he could get one, he had never seen them for sale. I am with you, I love mine with a cheap fleece bag and one of my old military 80% wool blankets- sounds a bit strange but it’s awesome!
Julian Dorrell - And you have some great ideas as well . I purchased 2 body bags about 10 years ago in Colorado Springs at Glenn's Army Surplus . Was going to call them and see if they still sell them and will ship , but they aren't open yet .... before 8:AM . 719-900-4553
Daves mat would work great inside or on top of a body bag .

Nav Star, I served 93 - 97 and since then I have purchased two also to pass on to my twins as we are beginning to enjoy the outdoors more. None of us like sleeping on the ground!
I have seen the Dutch ones as well as US issue and they are known by numerous names but most commonly (and less morbidly ) as combat stretchers and combat drag bags. If I had more, I would send Dave one as a Christmas/get out there and try it gift.
I originally commented on his bush chair/bed vid he basically made a body bag but with a little more thought about design and comfort in use. You should check it out if you don’t remember it from 2 or 3 months ago.
Holy Gunsmoke! You sew too! Unimpressed you sew with a sewing machine and you were on the floor I must say you so better on the floor than I do sitting at a table. You have also inspired me to make one of of your pad creations. Thanks for being so creative and cheap LOL. I love cheap
Okay so ignore those spelling errors. I typed them up correct but there's a storm in the air and you know how the Airways mess with your words
Thanks! I'm glad you liked it. Lol, I see ok. Sitting in the floor ain't easy and it's really tough on your back! Thanks for watching Bailey!
Lol, I'm used to auto correct messing everything up
@@Reallybigmonkey1 yeah well you should see what the words look like with autocorrect. I literally had to turn autocorrect off because it was calling people foul names. Good way of losing friends LOL
Lol!
" If you can dream it try to make it." You are an inspiration to me. Thank you so much.
Yep, and that's a good rule to follow if you want something they don't sell. Thanks for watching Edith.
More personal inspiration and excitement than NASA has given us in 60 years!
Lol, thanks!
By the sounds of it, this seems to be one of your favorite DIY projects. Thanks for all the work you do.
He turned into a little kid at Christmas.
Oh absolutely! I guess because it turned out to work way better than I had hoped for!
Pure genius.👏🏻
Snug as a bug in a rug pad!Love that idea , ideas flashing --next maybe two sewn together as a bag????Or tentinsulating liner under tarp Nice to see your happy face grinning with pride at job well done and happily encouraging others to use their noggins.Sewing is a good skill to have and you get better with time. Very handy for all to have amazing adventures with.. CAN'T NEVER DID A THING!
Funny you mentioned two sewn like a bag. I never thought about doing that but several people commented that and now I love the idea! Yep, nothing beats having sewing skills. It not only saves money but allows inventions to come to life! Thanks for watching Lavonne
This is one of your best Ideas for what I call a bed roll...It would be worth buying all the materials to make one ..I do not know how to sew on a machine and do not have one ..But I know a little business that would do the sewing... It is a place that sells the machines and teaches people how to sew
Sounds great brother and I'm glad you liked it that much! Oh yes, its absolutely worth making. I was shocked at how well it worked for me. I did learn from a commenter that this foam can also be bought at home improvement stores because its also used as an under layer for new wood floors. Thanks for watching
More Dave genius. Thank you for sharing. Why on earth have gear companies not snapped you up as their exclusive designer, I will never know.
Thanks, I'm glad you liked it. Man I have no idea why none are interested in my gear
I've used mylar blankets under different pads and it always helped keep the cold from coming thru , but your idea not only keeps cold from coming thru it seems to reflect your own heat back to you also. Great idea. I am going to try to make one maybe using cordura on the bottom and cotton or wool on top. I also like your idea of installing a zipper at one end for cleaning purposes. I think your one of the cleverest camper inventors out there. you are always finding better or different ways to enjoy life. I have stolen some of your ideas and I was never disappointed with the results. Please keep doing what your doing.
Man that sounds great! The ultimate pad would be Cordura on the bottom and wool on the top. Well worth making. I'm glad you like what all Ive made. Thanks for watching Charles
If you put the home-made pad on TOP of the inflatable one, I bet you'd never have to worry about cold ground again! Really great idea! I'd love to make a few of these some day!
Oh yes! Im sure with the two together I'll never have a cold back again! I'm glad you liked it. Thanks for watching
@@Reallybigmonkey1 you're welcome buddy! Been following your channel for years! This is another of many great ideas you've shown me. I appreciate all the work you do for these videos.
Seeing videos like this makes me glad my parents and grandparents insisted on learning how to sew. My buddies laugh and my wife used to until I took in the waist on her work pants and hemmed her jeans.
LOL, Theres always been some laughs around men sewing but thos of us men that do sew? We know how much skill it really takes to do it well. Ive always been amazed at the complexity of the machine itself.
Good one, I enjoy the found treasure. Not exactly dumpster diving, but recycling at it's best. My aunt was a quilter, so large scraps were often available. Sleep under a fleece quilt some time. The velcro is a great idea, for the next time. Dirt happens. See you in the next one
Thanks, I'm glad you liked it Jesse. Recycled, used, cheap its all treasure to me! I think the older folks knew the value of saving everything. Thanks for watching
I think.........by your reaction that you are thrilled at how well it worked. Now you'll have everyone looking for foam and mylar....lol. Thanks for showing us how to make it. I'm sure that sewing on the floor wasn't comfortable. I wouldn't be able to get up from there...lol. Take care.
And you are correct! I was honestly shocked at how well it worked. Oh it was a pain in the ole back working off the floor but it was worth it! Thanks for watching Lady B
I agree Paul. Dave totally deserves the best. He’s some kind of genius.LOL🌈👍👍👍👍👍👍👍👍👍👍👍👍
Thank you Paul!
Thanks Pat!
You could also tie off your bedding project, like they did with quilts in the old days. It will keep your bedding from bunching or shifting & keep everything intact. YOU, SIR ARE A GENIUS!!!
Good idea and thank you Lorene!
wow i have a ton of catching up to do here i see. Your channel is just fantastic for us who need to learn more about serious outdoor adventures. Just GREAT content as always and thanks for sharing. Gretings from WW2HistoryHunter.
Thank you my friend and it's always great to hear from you!
Your project is really cool and looks very doable for the average DIYer. I like how light it is.
Thanks, I'm glad you liked it Mary! Oh yes, its quite easy!
Some pads (thermarest, big agnes) actually have Mylar that hangs down on the inside of each chamber when inflated. Best pads I’ve used (insulated and non insulated) for comfort, warmth and weight are from Big Agnes. Not cheap though like you said. Always enjoy your videos.
Man that's good to know. I had no idea. I guess I didn't know because everything I own is cheap! LOL. Thanks for stopping by brother.
See ya in the next one...👍
Your neighbors must have a riot when they look out their window into your yard. : ) That is a great idea. Up here where I live that would be excellent. Another super invention from Daves Warehouse And Bunker. All the best my friend Paul
LOL. Paul my neighbors think Im nuts! I'm glad you liked it. Thanks for watching
I like this idea a lot. I may make one of these. I think that a waterproof bottom that goes up a little over onto the top would allow it to be used where there may be moisture in the soil that will evaporate up into the cloth. Also, you would not have to have a ground cloth. If you made the top with two layers of cloth, that you could get into, then you would have a complete sleep system. Just pull it out, unroll it and get in. You could make the top from fleece or line the top with fleece.
I like both them ideas Stephen!
Boy that almost sounds like the ULTIMATE COWBOY ROLL an that is one check of an idea
Wow! Your delight in your tested compleated project was great! When you said you love it, I believe you. Keep sharing your videos. Thanks! 👍
I hoped it would work but was shocked at how well it did! Thanks for watching Theresa
Well u would make a heck of a Christmas present wrapper lol, awesome video man,I bought a sewing machine just because I been watching u make stuff and I just had to try it.i think I have called the sewing machine every name there is so far lol but I'm getting better somewhat each day.thanks for sharing man,I definitely need to try this
LOL! Hang in there brother, me and my sewing machine went round n round until I got used to using it. Im finally at a point where I know what all to do with it.
Very funny, Nathaniel!
UA-cam is a great Teacher. 😉
Again brilliant. Air mattresses aren't good insulators at all. Because the air in it, gets cold. Foam or better Mylar is the best insulator against cold. Well done David! Thank you for sharing.👍😁
Thanks, I'm glad you liked it. They claim some air pads have insulation but, they still get blown up with air and air aint no insulator! LOL. Thanks for watching
Always exciting to see a new fun in the woods notification!
Great to hear that Jim!
That was awesome! Who’d a thunk of something that great from trash! I was so tickled at your reaction!
Thanks, I'm glad you liked it Terry! Nothing is trash to me, its all raw materials. LOL
Probably one of the best things you ever created brother! Gotta share this with a good friend who has a sewing machine ;-) Cheers, Marc
Thanks, I'm glad you liked it that much Marc! Share away brother and Thanks for watching
The Best Ever ! 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Hey Dave. It's been many years since you made this video, but I'm still working on procuring the foam. I researched it and it is called Volara. One of the reasons it works so well is because it reflects heat very well. It is closed cell foam, which means it's impervious to cold. It reflects heat better than mylar. I also discovered that Mylar is transparent! How a transparent material can be reflective is beyond me. I've always kept this video in mind. You are a brilliant man and I really respect/appreciate your ingenuity and your determination. Thanks again for your great videos! :)
Thanks for the info! I only knew it was foam. I had no idea it had reflective qualities. Take care and thanks for watching brother
That looks like a great idea. Thumbs up.
Thank you Lonnie! I'm glad you liked it Brother. Thanks for stopping by.
Excellent project little brother. Don't you just love that singer heavy duty? I got a singer simple when I wanted to make my own hammocks and it just didn't work as well as I wanted. I got that Singer heavy duty and have done a huge number of projects. It never fails. I am going to do this project since I want to do a double layer hammock at some point. Thanks for another awesome video!
Thanks Sis! Oh the Singer heavy duty is a beast! Over the past 7 years I've destroyed three sewing machines by pushing them too far. The Singer heavy duty has taken everything I've thrown at it. Great to hear you can use this project and thanks for watching!
Love it. The one thought I had was the layers moveing. I think either sew or tape them all together. Yes..zipper...lol
amy fletcher : That is what I thought as well. I used to make my kids’ bedroom sets ( bedspread curtains etc...) and if the stuffing in the middle of the bedspread was not attached at each corners it shitted and once it balls up it never looks or feel the same again. I even sewed lines vertically or horizontally, depending of the pattern to hold everything in place. The only problem I see with that would be that it becomes un-washable, but I don’t think that many commercial are washable. But you usually put a sleeping bag on top of it ( well... here in the North Pole anyways.) lol. And then the use of a zipper would be unnecessary. But what an awesome project! Awesome 😎!
The un washable part was because of the content of your sleep pad, my bed spreads were made of synthetic material that you could wash...just to clarify...😊
@@nicolehervieux1704 yes I was thinking quilt/bedspread type also. Just sew the foam and mylar in a few places and keep the zipper for washing.
amy fletcher : yes your idea is even better. Look at us watching his hard work and critiquing his sleep pad, lol.
@@nicolehervieux1704 how do you think he improves his ideas....lol He loves us...lol
I enjoyed the idea and the video. I wondered about how supportive it is for ones back. I suppose if it becomes an issue you could put it on top of the inflatable. Thanks for all your hard work providing these videos for the rest of us to enjoy.
Thanks Jere, I'm glad you liked it. It's fairly supportive and comfy since it's close to 3/4 in. thick. I'm sure I'll use it and the pad for extra comfort.
Great idea glad it works it will be interesting to see how it works on a field trip. You might want to start a business making and selling your idea.
Thanks, I'm glad you liked it Thaddeus. Oh Im sure I'll test and use this quite often!
I LOVE your laugh! And that insulating reflective pad is inspired!
Thank you my friend!
Very cool David. Very cool. I also had a chuckle out of how excited you got. With that awesome home brew non electric heating pad you could also put a cheap blow up mattress under it for the ultimate comfort sleeping system. So, another great invention by Dave the Reallybigmonkey. :-)
Thanks, I'm glad you liked it Robert! LOL, man that chuckle was from me being astonished! I truly couldn't believe how well it worked!
Awesome 👏🏻
Your enthusiasm is infectious! Love it!
Thanks!
Awesome. Great Project that works. Bet it would really be comfortable on top of the $80 sleeping mat !!
Thanks !! H.
Thanks, I'm glad you liked it. Oh yes, I have the Klymit static V so why not use em together. Thanks for watching
👍
I'm from the UK and just love your vids mate. This has inspired me to learn to sew. I got all that stuff hanging around apart from the camo . Awesome.
Fantastic to hear that Anthony! Man once you get into sewing you'll be shocked at how much custom gear you can make. Take care and thanks for watching brother
Great job Mr. Wizard...
Thanks, I'm glad you liked it!
Love that the project worked out just the way you wanted it to.
I have been unable to watch any videos for the past few months, as I have been homeless and job hunting. Fortunately I was able to couch surf during that time, but always had in mind the tips I have been learning on your videos, in case I had to rough it! Looking forward to catching up on some of your other videos I have missed in the meanwhile, once I am settled in to my new accommodating and job.
Thanks Mark, I'm glad you liked it Brother. Ah man I hate to hear what's happening to you right now. Hopefully something will pop up and this will be a temporary situation. Take care and I'll see ya in the next one
Thanks. Things are OK though. Soon I will be able to get back to trying to get back to bringing us closer to world peace. :-)
You have no idea how many times I have had to sew things on the go, I do 7 month survival every year and walking through the trees rips your clothes, I've sewn my pack several times, tarp, hammock, made inventions, you name it. To be a schooled survivalist you have to learn to sew.
Oh I hear ya and I agree! Every survivalist needs sewing skills
Alriiiiight!!! I love this improvement-over-store-bought DIY project. IOSB DIY.
Bicycle stores could also be a source of packing foam pieces (lots of foam wrapping on the bikes they bring in).
Thanks! I'm happy you liked it. Good thinking on cycle shops
Hey Dave,
Thanks for this episode man....''If you can dream it...try to make it'' says Good-
Ole Dave P....Glad it all came together so perfectly, you were so tickled, it was great
to see...You have once again cobbled-together a one-of-a-kind jewel...Great job !!
I'll just bet you thought you'd died and went to heaven when you saw that bolt

I'll bet you did go nuts over that fabric, I don't doubt that for a minute...How's
about taking us along with you on your next supply/scrounging/shopping run ? It
would be fun to hear your commentary while exploring for hidden ''jewels''. Just
a thought...still surprised about the PJ's though...haha... ATB man.
Excellent result Dave, I am glad that your flabber was gasted. Stay safe & be well.

Thanks, I'm glad you liked it Dave. LOL, man I was shocked at how well it worked! Thanks for watching
Fantastic Dave as always, Like I've said before about your projects your bringing to much common since to the outdoors . Could be you should slide that air mate into your envelope and have the best of two worlds warmth and comfort . Yup had to come down of the mountain because of the fires, just in case San Diego has a fire problem also it can go up like a torch also but were ready . Happy Trails Great Video
Thanks Mike, I'm glad you liked it. Yep, common sense mixed with cheap. LOL. I hope them wild fires go away soon. Im horrified at the damages its done. Take care brother and Thanks for watching
@@Reallybigmonkey1 cheap, that could be called more cost effective but I like cheap .Happy Trails
That’s what I say,.happy trails.👍
Great project. I applaud your creativity and ingenuity.
Thanks John, I'm glad you liked it
Very interesting product! I‘m just wondering if a mylar layer right under the camo cloth would insulate/reflect heat even better, as it would be closer to the body? Best greetings, Tim
Upon second thought: No! If the cloth gets damp or moist the mylar could conduct heat away. Your layering is better, I reckon!
Thanks, I'm glad you liked it Brother! That was my thought at first but just like you said, a thin layer of cloth may just allow sweat to form. Thanks for watching
👍
Thank you so much... that's perfect for a hammock I think, and if you keep the mylar tent together that's a shelter too. AWESOME 👍😎
I'm glad you liked it James. Yep, and I could add some tie outs to the bag to secure it to the ole hammock! Thanks for watching
Okay I'm at work but I know what I'm doing when I get home👍❤️
Sounds great Sheila! Now you have a cool weekend project!
Great idea ! 👍
Very nice end result!! It would be interesting to see a time lapse of hot water bottles with a thermometer on each on and see how long they stay warm.
Thanks, I'm glad you liked it. That's a great idea for a test! Thanks for watching
Why not just put a sun shade for vehicle window under your other pad/blanket?
Because they are quite thin.
colene henley that’s what I do. Works well
I also considered that, but dropped it. Completely wrong size for me... and the sun shade mat wears down pretty quickly on rough ground. The outer layers shown in the video would protect against that. Yes, if I had nothing else, I would certainly improvise and be glad to use a sun shade or whatever I had at hand. If planning and not having lost gear, I would go for what is shown in the video as it seems far more designed for the purpose. The sun shade mat is not bad, but the layered system shown simply looks a lot better.
Youve got me thinking Colene it could be made to work i do belive thanks

Hey David, thank you so much for sharing all your knowledge. I just found and subscribed to your channel. For some time I’ve been watching Suspicious 0bservers and Ice Age Farmer and others and learning about our Sun and how we’ll be affected by the changes. It’s important to know what all’s happening. Finding your site is excellent for what to do about what’s happening on a personal level. Finally some hands on techniques and information I can use to be more comfortable and prepared; though for some of what’s coming not sure any of us can go it alone, good neighbors are important.
Mostly I see comments from men on here, so hope y’all don’t mind a girl showing up. Anyway, I have a bunch to catch up on with all you posted, enjoying your sense of humor and “can do attitude”.
Blessings 🙏🏼
Hello Veronica! I'm always happy to share and I'm happy you like the videos. Since you mentioned the sun and what it's doing, I know of a video you will love if you haven't seen it. ua-cam.com/video/Zdr-maH3jtc/v-deo.html
Thanks David, now your YT name makes sense :) Enjoyed this, was a good interview for a rainy NC day. Whew, we be in trouble! He has good insight into our global situation. Bit of Cane and Abel story mixed in. I found a couple more YT video interviews of him to watch. Where I differ with his view is on the warming temps vs cooling. I agree gonna be big storm changes in coastal areas, well everywhere really as the climate adjusts. Think his MT area is going to be colder. Time will tell. I believe we’re living at end of empire; so I have gratitude and find joy each day, appreciate family, friends. Keep it simple. I trust some people will come through these times and a better way of living with natural world will result. Hopefully peace will too. 🙏🏼
Ahhhh, you had me at cheap.....................

Hey David
I recently came across this article "Scientists develop first fabric to automatically cool or insulate depending on conditions - Novo Scriptorium".
After watching this video of yours, I thought perhaps you and your subscribers that have "fertile minds" for DIY bushcraft may find it interesting as to what may be on the horizon.
Really enjoy your content.

Scientists develop first fabric to automatically cool or insulate depending on conditions
Despite decades of innovation in fabrics with high-tech thermal properties that keep marathon runners cool or alpine hikers warm, there has never been a material that changes its insulating properties in response to the environment. Until now.
University of Maryland researchers have created a fabric that can automatically regulate the amount of heat that passes through it. When conditions are warm and moist, such as those near a sweating body, the fabric allows infrared radiation (heat) to pass through. When conditions become cooler and drier, the fabric reduces the heat that escapes. The development was reported in the February 8, 2019 issue of the journal Science.
The researchers created the fabric from specially engineered yarn coated with a conductive metal. Under hot, humid conditions, the strands of yarn compact and activate the coating, which changes the way the fabric interacts with infrared radiation. They refer to the action as “gating” of infrared radiation, which acts as a tunable blind to transmit or block heat.
“This is the first technology that allows us to dynamically gate infrared radiation,” said YuHuang Wang, a professor of chemistry and biochemistry at UMD and one of the paper’s corresponding authors who directed the studies.
The base yarn for this new textile is created with fibers made of two different synthetic materials - one absorbs water and the other repels it. The strands are coated with carbon nanotubes, a special class of lightweight, carbon-based, conductive metal. Because materials in the fibers both resist and absorb water, the fibers warp when exposed to humidity such as that surrounding a sweating body. That distortion brings the strands of yarn closer together, which does two things. First, it opens the pores in the fabric. This has a small cooling effect because it allows heat to escape. Second, and most importantly, it modifies the electromagnetic coupling between the carbon nanotubes in the coating.
“You can think of this coupling effect like the bending of a radio antenna to change the wavelength or frequency it resonates with,” Wang said. “It’s a very simplified way to think of it, but imagine bringing two antennae close together to regulate the kind of electromagnetic wave they pick up. When the fibers are brought closer together, the radiation they interact with changes. In clothing, that means the fabric interacts with the heat radiating from the human body.”

3/4/22, 9:52 AM Scientists develop first fabric to automatically cool or insulate depending on conditions - Novo Scriptorium
Depending on the tuning, the fabric either blocks infrared radiation or allows it to pass through. The reaction is almost instant, so before people realize they’re getting hot, the garment could already be cooling them down. On the flip side, as a body cools down, the dynamic gating mechanism works in reverse to trap in heat.
“The human body is a perfect radiator. It gives off heat quickly,” said Min Ouyang, a professor of physics at UMD and the paper’s other corresponding author. “For all of history, the only way to regulate the radiator has been to take clothes off or put clothes on. But this fabric is a true bidirectional regulator.”
According to the Science paper, this is first textile shown to be able to regulate heat exchange with the environment.
“This pioneering work provides an exciting new switchable characteristic for comfort-adjusting clothing,” said Ray Baughman, a professor of chemistry at the University of Texas who was not involved in the study. “Textiles were known that increase porosity in response to sweat or increasing temperature, as well as textiles that transmit the infrared radiation associated with body temperatures. However, no one before had found a way to switch both the porosity and infrared transparency of a textile so as to provide increased comfort in response to environmental conditions.”
More work is needed before the fabric can be commercialized, but according to the researchers, materials used for the base fiber are readily available and the carbon coating can be easily added during standard dyeing process.
“I think it’s very exciting to be able to apply this gating phenomenon to the development of a textile that has the ability to improve the functionality of clothing and other fabrics,” Ouyang said.

Now that is amazing! I haven't heard of that, thanks for sharing that
CONGRATULATIONS PAL... Good to see the other side of the world some people has the same ideas that gravitates in the cheap but effective solutions which can be better than expensive industry products, I did the same and it worked really good... you are the best in DIY for outdoors activities...This channel should be called "Redneck but clever". Martin from Argentina. God bless...
Thanks Martin, I'm glad you liked it and that's great to hear you made this same set up! You know first hand how well it works. Thanks for watching
That was a truly amazing project. I also like the idea of Velcro or a zipper so the outer cover can be washed. Thanks for the video~
Thanks Brother, I'm glad you liked it. Another cool thing with a zipper is I can add or take away layers. Thanks for watching
Built one. The only cloth I had handy was a moving blanket, and it is awesome. Making another one for my son.
Sounds good to me!
Between this DIY video and your Ranger Roll Video. I have started working on merging a traditional bushcraft kit with some military spec gear to create a sort of "hybrid" that will work for my "ETC". And of course! Thank you for these awesome videos!
:)
Sounds good to me Ellen! Why not mix and match gear to suit your needs? Take care and thanks for watching my friend
How anyone could not enjoy this video is beyond me.
I absolutely love this sleeping pad. I wish I could sew.
Do you mind telling the model number of your sewing machine.
I was excited as you were that it worked.
Another great video, informative and entertaining.
Thank you for posting. Ken hughes
Thanks Ken! I have a Singer 4423 heavy duty. Thanks for watching
More "hot"ideas from the great one!!! I have been meaning to suggest you try the stretch stitch on the Singer sewing machine. It allows you to pull on the sewn items and not bunch or break the stitching...
Thanks Dr. Ron, I'm glad you liked it. When I first got my machine I tested the stretch stich and man its amazing how it works! I did use it on a few bags in the past but not often. Thanks for watching
Great video, I already know how to sew, I like your resourcefulness, I have a slogan at work, and yes I did steal it from Clint Eastwood, improvise, adapt, and overcome. You come up with some great ideas. Keep them coming.
Thanks, I'm glad you liked it. Man that's a good saying! Thanks for watching
I really like that sleep pad. I will have to get the stuff to make one. Great invention from a great inventor.
Thanks, I'm glad you liked it. Oh its well worth making! Thanks for watching
Man once again you knocked it out of the park David. It's always great to see what you will create next. Thanks for sharing
Thanks, I'm glad you liked it. Man no telling what I'll dream up next!
Hi David,
Been watching you for a number of years now and still admire your inventive sollutions. (Still my Shelter Master)
Last night i was out camping with a winter sleeping bag but with a summer tent and airmatress (exped rated till -5 celsius. I was cold!! Blaming my sleepingbag but the reason being my other gear.. if i brought my thermarest and a different tent i wouldn't be cold. Ground indulation is very important!
Greetings from the Netherlands!
Romin aka (deverrefietser)

Hello Romin! I'm glad you like my videos so much. Amazing how simple choices or changes in gear can make one freeze! Take care and thanks for watching
Good job! That pad is awesome, and you know that self inflating pad for $80 is still relatively cheap I have seen some for over $300. Some of them have down in them but any with only air will just make you colder because the air inside will never heat up.
Thanks, I'm glad you liked it. Ah man, 300? That is high! My 80 dollar one is supposed to be insulated but doesn't feel like it.Thanks for watching
Hi Dave, another excellent invention , keep up the good work,
Thanks Mike, I'm glad you liked it. Thanks for watching
Another great idea your amazing and we thank you.you should put a pocket on the outside end so you can slide some thing in to make pillow.that way it won't slide off 😀. Keep those wheels turnin
Thanks, I'm happy you liked it and I love your idea for the pillow pocket!
Very nice Dave. I think it will work well in the field. Happy camping!
Thanks, I'm glad you liked it Michael. Oh yeah, I bet its gonna be great out in the field! Thanks for watching
Back in the day when I was a kid in the scouts, we would buy air mattresses the same type you would put in a pool along with a ground cloth of some kind. You still froze in the winter. this is a cool idea gonna have to try it out.
I knew a lot of folks that did that! Amazing how the cold from the ground transfers to the air in them mattresses.
Very happy about ur latest success! Simple, cheap and it does the job. Can't ask for more than that. Well done.
Oh I was happy too Rich! I'm glad you liked it. Thanks for watching
I put a piece of bubble foil reflectics in my under quilt for my hammock. Under quilt is only rated for 0 Celsius. I couldn't believe the difference. It's about half inch thick. Two layers of that and some fabric would be good too. Great build
Oh I hear ya! It's amazing what this reflective material can do. Thanks for the comments and thanks for watching
I believe you were a wizard in at least a few of your past lives. Outstanding stuff.
LOL, Wizard of the woods! Thanks for watching
Dave you are a Bushcrafting camping out of the box Genius man I bet that does work great I’m on in Brother👍I’m planing on getting out this winter
Glad to see your doing well.
Best of the Holidays to you&your’s Have fun Be safe
God Bless us one&all”
Thanks, I'm glad you liked it and how I do things! All is well here, just too busy. Thanks for watching and may God bless you too.
Years ago, I saw a Dow Corning commercial about something that they made for the spacecrafts.
They used a foil layer and then a paper layer and then foil again, and repeated this many times.
They somehow sealed it together in a vacuum, so it made a many layer thermos bottle like panel.
So your idea is a good one,, like always, and, ,Thank you for sharing,,,
Funny how layers always do better than one thick piece. Also funny how vacuums work. That does something to the nature of materials that's hard to explain. I'm glad you liked it. Thanks for watching
@@Reallybigmonkey1
Thank you for all your work. You make life better for everyone,, and especially for those that pay attention. 😄😄😄😲😨😎
So glad you showed that.
Tell people how comfy it is too because of the contours.
I use this but never thought about the reflection part.
Also tried it with crossed contours but it was enormous when I rolled it up.
All the best
Thanks, I'm glad you liked it Keith
I made me one that is pretty light at least lighter than what I had been using. I made it out of left over building materials.
It is 5 layers thick. And just under 2 lbs. I have pictures and video but have yet to finish editing and uploading it.
The middle layer is a reflective sheet, and on either side of that is a layer of hardwood flooring underlayment. The underlayment has the plastic vapor barrier with thin foam padding attached to it. Then all this is taco wrapped with. Tyveck that I camo painted with left over paints. The good thing is that it lofts when unrolled by letting some air come into it. I then put 4 grommets, two on each end, so that I can secure it to where it doesn't move around in my hammock.
It is useful for ground camping too because it is wide and waterproof so I don't need an additional groundsheet.
I think I may have gotten the idea from you. Thanks Dave. Maybe one day I will finish the video. Meanwhile I have two others that I hope to upload tonight. Thanks again for your videos.
Sounds like a very cool project. I can't wait to see the video
Thank you for the idea my brother!!!
Great-simple project!
Stay safe and keep having fun!
Thanks Brother, I'm glad you liked it! Enjoy the project!
David, I'm pretty new to your channel. I've only started using youtube the last couple of years more regularly for entertainment and education. The world doesn't want to hear a mans problems so I'll spare you mine and just say that your work has enriched my life more than I care to explain, or anyone would care to hear. I just might have to learn how to sew so i can make me one of these darn things. Thanks for all you do, God bless you and your boy Nick.
I love hearing comments like this. I hate hearing what you're going through but it's good my videos add to your life. There's too much negativity in the world. I try my best to influence fun and positivity. Take care and thanks for watching
@@Reallybigmonkey1 Subscriber for life my friend.
Love it you get happy over your diy project just like me 😂 it was fun to watch You make this it got me exited just because of your happiness haha brilliant. Maybe i will make one and try it out next time im out camping in the snow 🫡
Oh it always makes me happy for some homemade to turn out good! Thanks for the comments and thanks for watching Andy
It's always nice to wake up w/toasty buns on a cold day.
Thanks for the tip,
Chris from Missouri
LOL, yes it is Chris! I'm glad you liked it. Thanks for watching
Excellent sleeping pad, keep up the good work, thanks for sharing.
Thanks Michael, I'm glad you liked it.
**tented fingers like Mr. Burns** Excellent :)
You could also make sitting pads with the same design :) The only potential problems, or design improvement, that I can see is that the layers might shift after many rolls and unrolls. Perhaps gorilla taping the sides or ends before inserting into the camo sleeve might prevent that, then again it might make it worse. Great video as always Dave :) I think I'm gonna make sitting pads for my winter day camps :)
LOL, I love Mr Burns. Yep, this would make a great sitting pad. With the mylar in a bag shape Im hoping it wont shift much. Tape will cure that if that happens. I'm glad you liked it. Thanks for watching
Love your videos Dave. There's a product out there called Reflectix. It's used for insulating floors, cielings and hvac. It has mylar on two sides with like bubble wrap in between.It's a game changer. I think it's maybe 1/4 inch thick but it sells in thicker widths. You can get it any where from 3ft thick up to 60 inches. The price isn't bad either. It says it reflects 97% heat. Sold at Hardware stores. You wrap it around a cup or thermos and will keep hot stuff hot forever!
Thanks! I'm glad you l like the videos. I've seen that bubble version of Reflectix but haven't used it much. They make a super thick flat version of Reflectix that I used on my Dakota pit shelter years ago
Good idea that Dave, looking forward to the first field test you do with it, all the best to you.
Thanks, I'm glad you liked it. Thanks for watching Tom
Outstanding. Only mod I would do due to my old bones would be, I'd place that one inch foam pad inside the Mylar for padding then do the rest like you did. Since it's a camping pad and not a shtf pad I wouldn't care to much about the weight.
Thanks, I'm glad you liked it Greg. The more padding the better!
YAY! Another good idea brought to fruition by a motivated southern gentleman! Good Job! You never know if that dog is gonna hunt until you test 'em :)
Thanks Don, I'm glad you liked it. Yep, gotta test everything! Thanks for watching
Such a simple idea anyone can do. Excellent video. Think I'm going to be making this one soon.
Oh yes, simple and cheap! I'm glad you liked it. Thanks for watching
G’day Dave, long time viewer here, here is an idea..I made covers for our sleep pads, they are like long pillow covers, meaning no zipper at end just sew in an extra flap like the fold in a pillow case. I love DIY stuff as well. Hooroo from Mozz in Oz
Good idea! I may just make the second one that way! Thanks for watching Mozz
I would leave one end open to a foldable flap as to remove the insides to be able to wash the cover. Just a suggestion but you are far superior than me at being creative. Your videos are getting my mind to start functioning on creativity 🤣
This was just an experiment to see if it would work. It worked so now I need to refine it with your idea!
You have some out of the box ideas, and they are pretty cool
Out of the box is the way to go! Thanks for watching Christine
That is so awesome. Such a great project. I know of a furniture place close to home to get the foam. I already have a collection of the emergency blankets, and I have a place close for material. But I don't have a sewing machine. And that is a lot to sew by hand. Lol
Thanks, I'm glad you liked it Tressa! Ah ya gotta get into sewing! It can save you a fortune and its fun! Thanks for watching
Very nice Dave! Another great idea! Thanks!
Thanks Carl, I'm glad you liked it brother
Great idea. Can’t wait to try this for myself. Thanks for all the videos.
Fantastic to hear that and I'm glad you like the videos!
Good vid Dave..I bought a cheap foam exercise mat for my bug out pick up truck and topper, 72 X 27 inches, 3/4 inch thick. I think will do the same job. It won't be layered but with mylar and covered with cloth it should achieve the same results. Good one bud.
Thanks, I'm glad you liked it. Yep, it may just work. Be sure to cover it with cloth and never let mylar touch your back. Thanks for watching
