We updated our BaseCamp™ Therm-a-Rest® mattress with lighter, softer fabrics on the top and bottom to improve its comfort and feel while reducing weight. It’s another enhancement to the straightforward, workhorse design that’s been providing dependable comfort under the stars for over 40 years. Crafted on a foundation of time-tested materials and components, the BaseCamp™ mattress is lightweight, compressible and now softer than ever, making it an even better travel companion. Includes stuff sack.
