Who says camping has to be uncomfortable? It isn't when you have the Therm-a-Rest Mondo King 3D Sleeping Pad. With 4.25 inches of quality thermal foam, this pad offers excellent support and all-night comfort, plus a 7.0 R-value to help you stay warm and cozy. It features a self-inflating pad with a TwinLock valve that fills and removes air from the pad much faster than the standard valve. The pad's construction makes it easy to compress for storage in the accompanying sack, which also features a built-in pump.
