ZPSwrote a review of Therm-a-Rest ProLite 4 Sleeping Pad on December 3, 2008
One of my favorite pieces of gear. I have owned this pad for over 3 years and it still works like the day I bought it: fantastically! It is comfy, warm, easy to pack, light, and small. Unless you prefer a folding pad for packing reasons, I would not recommend any other pad.
