Thermarest's most technical pillow functions as a compression sack for your mattress and has a built-in Stuff-it pillow for comfort on trail.

Stuff clothes or other soft items under the pillow panel for cushioning without adding extra gear to your pack.  When you're packing up, roll the mattress with the warp-it pillow attached and secure it with the sewn-on compression straps.  Your sleeping pad remains protected inside, eliminating the need for a stuff sack.

Functions as an integral part of your mattress an attaches easily to your backpack.  Machine washable.
