I just found this page from gossamer gear. It’s no joke. You can cook your food in your crotch, while you hike! I have done some searches and some people swear by it. For those ultra light folks out there who want to go without a stove this is one option. Not sure how the coffee would taste…
I have not yet tried it, but the concept is good enough. I’m not fond of the notion of a leak however… Let me know if you have ever tried it.
