An extra-wide, 3"-thick self-inflating sleeping pad that keeps you off the cold, uneven ground, with egg-shaped air cells and a built-in pillow for back and neck support. The built-in pump inflates it in 30–60 seconds and deflates in one, and it packs down to the size of a water bottle. Side buttons let you connect two pads into a double bed — great for hiking, camping, and backpacking.
