[Expansion and thickening] The size of this camping pillow is amazing. The inflatable size is 200cm x 70cm x 6cm, which is 1.2 times the size of a traditional camping pillow. The large mattress is more convenient to use, and the folding size is 13cm x 13cm x 30cm. The most important thing is that the camping pole is thickened, but the weight is only 0.8kg. [Dual valve construction] Easy to inflate and quick to pop down. The first air valve has a built-in foot pressure pump. The pump does not need to be prepared separately. Simply press the pump with your feet to inflate the pad (the pad fills up in about 25 seconds). The second air valve can be deflated in seconds thanks to its large valve. Ergonomic design: Unique groove-integrated cushion design. It is more suitable for the curvature of the human neck and head, providing better support and protection for the neck and head. Allow you to sleep comfortably outdoors. The polygonal design makes the air column fuller, can evenly distribute the pressure of the human body, and is not easy to be affected by uneven ground and heat. [Good durability] The sleeping mat is made of high-quality 40D nylon composite fabric and a TPU coating, which has excellent softness and offers you a comfortable experience. High quality materials are also better waterproof, breathable and wear-resistant, so you don't have to worry about leaks. Easy to clean with a cloth or sponge. Both sides of the sleeping pad are equipped with splice buttons. Two air cushions can be connected to form double air cushions, or multiple sleeping pads can be connected together, which is convenient and interesting. It is very suitable for outdoor activities such as camping, hiking or cycling.
