Ultra-light Thermarest pad, I think it's the same one jiott mentioned. For a stove I have had many differnt types. When I was in Okinawa I sold an old Optimus (99?) multi-fuel that fit into a small square aluminum box that doubled as a pan, one of my biggest regrets. Awesome little stove. Have the MSR International and old military multi-fuel stoves but now days the item I carry most everywhere is a Jet-boil, it all stores into the cup and is fairly stable and heats water up FAST!
I recently read reviews on a cot and other items that were super light weight and I knew I wanted one but can't remember where I was reading about them.
