The Cosmo is one of our most versatile and durable sleeping pads, offering 3.5 inches of plush, shoulder-saving loft and a stable, comfortable sleeping surface. NEMOs popular integrated foot pump allows you to inflate your pad in less than a minute using only your foot. This inflation is vastly superior to other methods, including batteries, pump bags, or using your lungs to inflate your pad, especially after a day on the trail. The Cosmos lateral baffles are less noticeable than vertical baffles, and prevent the sides of the pad from curling and tacoing around your body. The large Pillow Baffle at the head end of the pad ensures that your pillow doesnt slide off in the middle of the night, and gives a couple extra inches of height for supreme sleeping comfort. Cosmo is constructed with durable 75-denier polyester fabric laminated with an airtight polymer film, and subtly embossed to enhance tear strength.
