With a cushy 2.5-inch thickness and soft-touch stretch fabric upper surface, the REI Camp Bed 2.5 provides plush comfort for base camping. Horizontally cored foam is engineered to be lighter weight and more compressible without compromising warmth. Quick-closing, high-volume-airflow valve allows the pad to inflate and deflate quickly. Durable 150-denier polyester bottom surface resists wear. R-Value equals 4.5. Stuff sack included protects pad during transport and ensures a neat parcel every time.
