The NEMO Cosmo 3D sleeping pad uses body-mapping technology, lateral baffles, and super-tough fabrics to give you a strong, comfortable pad. Promising campers restful sleep, the pad's stable geometry means it’s less prone to move out of position at night. The 3.5-inch pad uses 3D body-mapped baffles to provide a cradle-like cross-sectional shape. This reduces the risk of you rolling off of the pad or the pad slipping out from under you. The horizontal baffles are also more comfortable than vertical baffles and prevent the sides of the pad from curling around your body. An elevated head region provides increased comfort. The mattress's durable 75 denier fabric is laminated to increase tear resistance. A zero-profile, multi-functional, micro-adjustable valve that allows fast deflation. Also included is an integrated foot pump. This makes setting up easy and prevents your warm, humid breath from entering the bag where it will cool and condense later. The pad is rated for use in temperatures of 25 to 35 degrees. The NEMO Cosmo 3D sleeping pad is available in Regular (72” x 20”), Large (76” x 25”), and XLarge (80” x 30’) size options.
