If you are camping near water, why dont you have this yet?
This item is the only thing in my UL setup I am not willing to ditch in the pursuit of having a pack so light it would make a school kid jealous. This thing is sweet. Ive never tried to sun warm it, I always add some hot water from the stove.(filled it with clear creek water and warmed it in scummy hot springs a couple times also) The thing that makes this so sweet is it has so many functions: shower, faucet for washing hands/dishes away from the water, camp water storage, dry bag, pillow.Mine has proven fairly durable so far. Only one complaint, just about everytime I get ready to use this in cold weather, it gets windy as hell and I freeze. I emailed Sea to Summit about this but they never got back to me.
