Ah, see this is like one big NASA patch away from the chef's kiss award for retro-futuristic home care. Diving into similar products on Amazon, and the customer review photos, also generated a lot of calories and warmth here as I couldn't contain the laughter in the end. An intrigued type of laughter though for sure. (Not _quite_ as effective for overall body heating as the effect of reading "sesame oil" hair conditioner reviews where people divulge that their grandparents were cooking family meals by stirring meat & veggies around in hair product for about a month before anybody noticed. But close.) I have some mylar emergency blankets in my car which I see are now advertised online as "thermal foil sauna blankets," so some experimentation in the space may be called for. Thanks op!
