lightweight air mattress for 2 people. Comfortable, waterproof, and easy to use and transport. It features a double valve for inflation and deflation. Perfect for spending nights outdoors. The FC-11 Diamond is perfect for outdoor adventures or as a replacement for a bulky sleeping pad. It's made of durable, waterproof nylon with a TPU coating. It effectively insulates the body from cold or damp ground. It packs down compactly for easy transport and storage. Diamond-shaped air chambers provide excellent body support. Furthermore, it's more difficult for body-heated air to escape from the spaces between the chambers. This design, along with the 6.5 cm thickness, provides better insulation from cold ground. A double valve is also used. The first layer is used to inflate the mattress. The second layer speeds up the deflation process. The mattress comes with a pump that can also be used as a waterproof bag. Naturehike has been producing high-quality outdoor equipment at affordable prices since 2005.
