Re-engineered to be 20% warmer than the previous ProLite 4, the ThermaRest ProLite Plus Sleeping Pad is built specifically for cold-weather adventures, ski touring, backpacking and mountaineering. Featuring a tapered design to reduce bulk and carrying weight and built with a die-cut foam construction to provide thermally efficient performance, the ProLite Plus delivers a great night's sleep.
Excellent
I was just on a canoe trip on the Colorado river and has a opportunity to use my new pad and it worked perfectly. Also the customer service that Altrec had given me was excellent. If you have ever camped on the Colorado River you know their is lots of rocks of varying sizes I couldn't feel any of them.
Great Pad
I recently got this pad and tested it out on my concrete deck. I slept just fine. The 3/4 length is a nice compromise between a true ultralight pad and a full length pad. This pad compresses down extremely small, which is nice. I opted for this instead of the ProLite (not plus) because it added slightly more weight/size for better insulation.
No complaints
Used the pad on Whitney and GC. Temps were pretty warm so I cannot comment on that part of it, but was happy with pads weight and compactness.
