Andrew G.wrote a review of Therm-a-Rest ProLite 4 Sleeping Pad on September 16, 2008
I love it. I have two and they are both very quality built. They DON'T self inflate unless you have quite a bit of time to let them lay out after you unroll them. I tend to set up camp late and want them inflated fast so I have to blow into them. Very light and comfortable. I used the first one for a couple years and then bought my girlfiend one just like mine because I knew it was a good sleep pad. It's also very warm in cool weather. On 45-55 degree nights, the ground temp is unnoticable. I haven't had it in any colder weather than that yet. It does take a little effort to get it rolled up small again but that's part of it. Hope this helps. Happy camping!
