Best cover available!!! Very comfortable!
Super light weight, and fitting perfectly to my Therm-a-rest NeoAir, I leave the cover on even when I pack it away. It still fits in the stuff sack that the mattress came with without any issues at all. As far as comfort goes, I've tried several other covers before dropping a few bills to get this one. This is by far the absolute best; it has the feel of my sheets at home (vs. the sticky feel of the mattress by itself or other cheaper covers available). I love it!
