it's a tossup between my pressure cooker and my spacebag. I use my spacebag for EVERYTHING from pillow, waterbottle, shower, seat, hooch maker, flotation device and lover... well maybe not lover. but it's small as shit, and the most multiuse thing I've ever had in a piece of garbage. The pressure cooker... well... I cook good shit (beans and goat) fast.. and when I'm living in the woods it makes the world go round.
