User Review: Therm-a-Rest Men's ProLite 4
Price Paid: around $100 I think
I have both the ProLite 4 long (for winter use) and the ProLite 3 shorter version for summer/all around. Obviously I like the pads enough to have bought two of them, and providing I can get enough air into it for firmness (the 3 has an annoying valve issue that prevents me from puffing it up more than half-firm), they are quite comfortable.
However, my biggest gripe with Thermarest, and it has been for years, is the ridiculously slippery fabric they consistently put on many of their pads. When I saw the ad for the ProLite, featuring 'textured dots on the bottom' I was excited...thinking they would be like sticky dots of some sort. They're not. Combined with the always slippery nylon surface of a tent floor, I find myself drifting/slipping throughout the night on anything but the flattest surface.
Before anyone comments that I need to select better tent sites, keep in mind that this isn't always possible. Many campgrounds have inadequate tenting sites (such as a dedicated tent platform) and on snow/glaciers when I've been on expeditions, it's simply impossible to level it completely.
I really, really wish Thermarest and Cascade Designs would somehow make the surface slightly sticky. Until they do, their mats (regardless of thickness, lightweight design features, etc.) will never go above 3 stars for me.
