Hi TJ, Thank you ;-). Now back to reviews again. The research for those How To videos is so time consuming and difficult that I need a break now. Although... I am waiting on some shoes for the waterproof and breathable shoe video.... Yes, Still small but growing. Cheers, Gijs
Excellent. I have been looking for ways to approximate my clothing performance at home without having to send it to a lab. I don't need exact numbers; just ballpark. No need to compare my results with other sources. Inverted cup looks like an easy way to measure MVTR, as least for fabrics that are water resistant. I see that you have done a similar vid for measuring water resistance. 1) Is there a way to modify the inverted cup test for fabrics that are not water resistant? You mentioned a variation including a PTFE membrane: Would that do the job? How does that variation work? 2) Have you done anything similar for air permeability? That would complete the picture.
Hi Bill, Thank you for kind words. Your questions. I hope you understand that I am not sharing everything I do. Next to my UA-cam channel I do give lectures and workshops (or is that the same?) about these topics and even there I don't tell everything. It's got to do with how I do make some money. Don't hesitate to send me an email with your details and I'll see what I am willing to share. Enjoy the Outdoors and Stay Safe! Cheers, Gijs
@@OutdoorguruGearReviews USA. Retired engineer, lifelong backpacker. Love my OR Ferrosi soft shell. Looking for a windshirt with similar breathability, but not sure that such a thing exists. Curious about air permeability and MVTR of my Columbia Silver Ridge Light PFG shirt. It's a sun shirt, but I find that it does break the wind slightly when worn over a light base layer. It isn't a windshirt, although I do use it as one (in mild weather). I've recently been introduced to fabric tech by some excellent articles at BackpackingLight, and have been fascinated by the science. It was great to find another person who knows a lot about the fabric tech (you). No professional affiliations. Just incurably curious.
Can only be the Inverted Cup since it is rated at 26000 g/m²/24h. But.... I tried to find it on the FR website and I could not find how they test it. FR is not open on everything.
@@OutdoorguruGearReviews Ya, I know the specs, but can't find an official methodology from Fj. The Keb Eco-Shell has been amazing regardless. :) One of the best shells I've ever owned.. :)
Yes I have but there are already so much outdoor brands out there that In don't think I stand a chance in teh competition. But... maybe do't agree....? Enjoy the Outdoors and Stay Safe! Cheers, Gijs

@@OutdoorguruGearReviews Fair enough, but you did tell us to ask you anything. :)
And I am happy you did! Where are you from?

Thanks Mehmet!
Where you at bud?
Sorry Matt but I don't understand the question 🙃. Do you mean where I live? Enjoy the Outdoors and Stay Safe! Cheers, Gijs
Do you know what would help the breathability of any fabric is small air mattress fan to suck the moisture out of the body🤔😁
Which rain jacket do you recommand for cycling?
Hi PonderDuke, What kind of cycling? Enjoy the Outdoors and Stay Safe! Cheers, Gijs
@@OutdoorguruGearReviews Day tours, or vacation trips but also just the daily commute to work. Keep up the good work! Thanks for your content.
Hi G, Great job again!
Question: do you know which method Fjällräven uses for their eco-shell? Thanks! :)

I know TTD, I'll give my contact a mail about this.
Hi the problem I have with the majority of these tests does not resemble body temperature and fabric reaction. 🙄
Hi Al, Yup, true. In a lab they have about 24 variables..... in the outdoors...🙏 Enjoy the Outdoors and Stay Safe! Cheers, Gijs
You ever thought about making outdoor gear?
