Thanks for the information! I really like multi-purpose items, especially while backpacking (like your belt doubling as a tourniquet). For example, I have this chair that I love because it is so versatile! It is a luxury, for sure, but is relatively easy to strap on to your pack. You can use it as a kneeling pad, bed roll, and, or course, a chair. In a pinch, the supports are strong enough that it could be used as a splint. Plus, it is much more comfortable than those foldable "soccer" chairs. Mine is rarely put away with my camping gear, I use it too often!
I have always wondered if those things are worth their weight, I'll have to pick one up! Thanks!
I'll warn you, once you get one, you won't be able to go out without it!
