it's small, light and compact, but doesn't offer much comfort. but that's not the point. if you want comfort when sleeping outdoors then get and inflatable mattress. if you want to stay wammer, then this is good for preventing conduction of your body heat to the ground. a good addition to your outdoor sleep system. it's not so tough and won't last long but it's very cheap and can be used with an existing roll mat or inside a hammock etc.
