ATEPA HybridLoft 3 Ultralight Self-Inflating Sleeping Pad | 2 lb Compact Camping Mat with 4-Side Compression, R-Value 2.3, 3-Season Backpacking Pad

Packs Like a Water Bottle. Sleeps Like a Foam Mattress.

Meet the ATEPA HybridLoft 3—the self-inflating sleeping pad that redefines lightweight comfort. Through advanced 4-side compression sponge technology, this high-density foam pad expands to 18× its packed size while weighing just 2 lbs and rolling down to the size of a standard water bottle (12.6" x 5.5"). The result? Traditional foam-pad support with inflatable-level packability—a true breakthrough for ultralight backpackers, fastpackers, and space-conscious campers. The self-inflating design sets up in minutes with the included 2-in-1 pump sack, while the 30D elastic top fabric feels soft against your skin and the 190T TPU bottom resists moisture for seasons of reliable use. At 72" x 21.7" x 1.2", the HybridLoft 3 fits perfectly in narrow tents, bivy sacks, or vehicle sleep setups. Light, compact, and remarkably comfortable.
