Therm-a-rest Ridgerest shorty
I got my ridgerest shorty just before a 10 day trip to Alaska for winter survival school. I was impressed at how well this pad insulated against the frigid snow. Not only did I use the shorty as a ground pad at night, I also used it as an insulated seat during the day. The foam it is constructed from is extremely comfortable and the ridge/valley design makes it extremely warm. I would recommend it to anyone looking for a reasonably priced 3-season pad, or as part of a multi-pad winter sleep system.
