Thermarest Basecamp AF Self-Inflating Sleeping Mat

Providing lofty luxury without the weight, the BaseCamp™ AF uses advanced AirFrame™ Construction, alternating foam and air channels to drastically reduce weight while amplifying loft with minimal bulk for bump-swallowing comfort. This self-inflating mattress packs small and comes with a new and improved stuff sack with easy-carry handle.

Air Frame Construction is really quite simple. It uses alternating channels of foam and air to create a skeleton of foam within an air mattress. The resulting hybrid of technologies offers the best of both - the high-loft comfort and compressibility of an air mattress, and the convenience, added stability and support of a self-inflating mattress.

Packs Small: Air Frame construction minimizes bulk for easy packing.
Stable Comfort: Exceptional thickness with stabilizing foam support.
Durable: Proven materials and craftsmanship offer exceptional reliability.
Self-Inflating: Compressible foam core expands to inflate; add just a few breaths for your desired firmness.
