Any camper will appreciate the value of a good sleeping surface in the outdoors. It can make a big difference between a tedious or an exhilarating experience in the wild. And that's where the Weisshorn Double Self-inflating Mat can help make resting a lot more comfortable for the happy wanderer. As the name says it all, the water-resistant mat self-inflates through built-in valves in just 60 seconds, presenting you with a smooth sleeping surface amidst all types of terrain almost instantly. Made from high-density 2.5cm thick polyurethane foam, the mat has an anti-slip polyester pongee bottom. That way, you lie on a smooth and comfortable surface with a mat that does not slip or move with your every turn while sleeping or shifting around. The mat is suitable for double use. Need more resting surface? Just connect the two mats via the built-in buttons for an enlarged area. In fact, you can extend the mat multiple times through this simple and convenient process. And when all is done, just roll up the deflated mat and pack it away.
