☆ I unfolded it indoors once to check if it would inflate, and it has been unused since then. There is some discoloration due to aging, as shown in the photos. The bag has a few scratches. The following is from the product introduction HP: Employing the latest production technology and an improved air pump, inflation is easier and air leakage is reduced. With a multi-layer structure of TPU + 41D nylon and waterproof processing, this camping mat is easy to clean, even when used outdoors; simply wipe away dirt with a wet towel! The ergonomically designed air pillow promotes restful sleep by keeping your neck and cervical spine in a natural shape, allowing you to sleep soundly and lightly, eliminating the need to carry a separate pillow, making it more convenient. This is the perfect camping mat for camping, mountain climbing, and more. With an industry-leading thickness of approximately 14cm, you won't feel the unevenness of the ground, and there's no bottoming out. It also blocks out cold or heat from the ground, ensuring comfortable sleep. Compared to the honeycomb structure of conventional products, the inside of the Sable mat has an elastic hand structure and adopts annular welding technology, providing high elasticity and evenly distributing body pressure, preventing side-to-side rocking and body sinking, and supporting the entire body in a balanced manner. The air mat's storage size is only about 35*15cm, and it weighs about 990g, which is lighter than ordinary air mats. When not in use, it can be folded and stored in the storage bag, making it very convenient to carry. It can be used in conjunction with a sleeping bag and is also recommended as a disaster prevention item in the event of an earthquake or other disaster.
