This sleeping pad has TPU lamination and is tear-resistant, water-resistant, and practical. With a quick valve, you can inflate the pad with just 10-15 breaths, while the deflation only takes a few seconds. The inflated pad features specially engineered cell patterns that contour to the human body and provide comfortable, balanced support for your back. With a built-in pillow, you can have a nice sleep without buying an extra pillow or worrying about the pillow slipping away. Its flexible structure also fits perfectly in a chair or a hammock, under/inside your sleeping bag, so you can pursue a cozy leisure life even outside. Pack the lightweight deflated pad in the storage sack and stuff it in your backpack to set out on a brand-new journey.
