Just purchased the Thermarest Prolite camp chair sleeve from REI. It weighs in at about 10 oz in addition to the weight of my thermarest prolite 3, but will easily be worth it in my mind. Here is a picture.



It is definitely more comfortable than sitting on the ground, a log or a rock. It also looks to be fairly durable and should protect the thermarest pad from punctures. I'm looking forward to bringing it on my next trip and keeping my butt off the cold and wet ground. The last thing I want to do after a long day of hiking is stand.

I'll take my "luxury" item over a slightly lower pack weight anyday!!
