①. This camping mat has an inflatable size of 193cm x 60cm x 6cm, which is 1.2 times larger than a normal camping mat. The large size makes it more convenient to use, and when folded, it measures 20*10cm. It is thick, yet weighs only 68.0 kg and deflates quickly. The first valve is equipped with a foot pump, so there is no need for a separate pump; you can easily press the pump with your foot to inflate the camping mat (it will be full in about 25 seconds). The second air valve allows for inflation in a few seconds due to its large size. ②. Ergonomic design: The unique integrated support and head section are more suitable for the human body structure, protecting the neck and head and allowing for comfortable outdoor sleep. The polygonal design makes the air columns fuller, which can evenly distribute body pressure and is less affected by uneven floors and heat. ③. The sleeping pad is made of 40D composite nylon with a TPU coating, offering softness, water resistance, air permeability, and wear resistance, so you don't have to worry about leakage. It is easy to clean with a cloth or sponge. ④. There are zippers on both sides of the sleeping mat, allowing multiple mattresses to be connected. The portable folding camping mattress is suitable for outdoor sleeping bags, hammocks, travel, tents, cars, beaches, backpacks, etc.
