In camping, a ground pad, sleeping pad, sleeping mat or roll mat is a simple device often used in conjunction with a sleeping bag. Its purpose is to provide padding and thermal insulation. All types currently available use air as their primary form of insulation. Here at Outdoor Shopping we offer the best ultralight, foam, folding, and roll up mats just to name a few. Ultra light mats are great for backpacking and traveling cross country. Closed cell foam is used to produce mats that can be used without requiring any inflation. Closed cell foam pads are lighter and more durable than their air-filled counterparts, as they are constructed of fewer materials. Many may also be trimmed to size should the user choose to do so.
