Stock #: 641Q-

Cosmo™ has everything you need in a versatile pad: a built-in foot pump for fast and easy inflation, 3 to 4 inches of plush, shoulder saving loft, and a raised baffle at the head end to supplement your pillow.


  • HORIZONTAL I-BEAM BAFFLES: The horizontal I-beam baffles in Cosmo™ and Astro™ give you maximum comfort. Horizontal baffles tend to support body contours better than vertical baffles since the sleeping pad resists folding around the body’s longitudinal axis. The I-beam baffles ensure a flatter sleeping pad surface and eliminate any bouncy feel when inflated.
  • 75D POLYESTER LAMINATE FABRIC: High abrasion-resistant polyester laminate fabric is engineered for excellent weld strength for airtight bonds. This fabric is embossed with a subtle NEMO shield pattern to add strength.
  • INTEGRATED FOOT PUMP: Give your lungs a rest with Cosmo’s™ integrated foot pump. Based on the principles of the Nemoid™ foot pump, the integrated foot pump draws in air using dual 1-way valves and rebounds with each stepping action to ensure efficient setup.
  • EASY INFLATE/DEFLATE VALVES: Multiple one-way inflation valves ensure a quick and efficient inflation of Cosmo™ series sleeping pads. The valves help draw in air that is then transferred by the foot pump to fill the sleeping pad baffles. When packing up your Cosmo™, simply close the inflation valves and open the large dump valve on the underside of the pad to expel all of the air.
  • SMALL PACKED SIZE: NEMO sleeping pads use airtight valves that allow you to squeeze out every last drop of air when packing up camp, greatly reducing the pack size. Depending on your pack needs, sleeping pads can be folded at different widths to accommodate available space.
