This excellent technique is being referred to as the Palmer Furnace. It is said that the inexpensive SOL Survival Poncho is a really good choice in place of the large garbage bag, and that the Poncho doesn't tear like Mylar does. A SOL (Survive Outdoors Longer) 1/2 Persons size Heat Sheets Reflective Blanket is also worth considering. They also make bivvy bags from the same material.
Adding this to my pack for my trip to Roppel in a few weeks. Thank you for this video! It could very well save a life.
