User Review: Therm-a-Rest Men's ProLite 4
This pad is great. I don't do any winter camping, but Alberta/BC nights can get chilly in the mountains, and I sleep cold, so I went with the 4 over the 3. I figure the extra r-value and thickness seem worth the small extra weight. I usually put 2 breaths into it for a full inflation. I am 6'1" and have the Regular length, it is perfect. I cannot believe how much more comfortable and warm it is compared to those old blue foams I had slept on. Highly recommend!
