Even if you are roughing it in the outdoors, that doesn't mean you have to rough it at night. The NEMO Roamer Self-Inflating Mattress - XL Wide makes staying comfortable at night easy. Although it comes in a small package, it doesn't lack in thickness. It features the brand's Flow Core system and Laylow zero-profile vales. Combined, it means inflating it in seconds. Deflating it is also just as fast and easy. The top of the mattress is a soft, stretchy fabric that is made with recycled materials.
