The innovative NEMO Cosmo Air is a compact and lightweight inflatable sleeping pad. Providing a 3" sleeping base while weighing less than 2 pounds (for the Regular and Large sizes), the Cosmo Air is ready-made for 3-season backpacking. An integrated foot pump makes inflation easy.

The inflatable design of the Cosmo Air provides 3 inches of cushioning for a comfortable night of sleep. Horizontal baffles create a more stable sleeping surface than you'll find sleeping on the vertical baffles of traditional inflatable pads. The Cosmo Air's 75D polyester fabric is lightweight and durable. Dual valves (single valve on the 20 Regular) combine with the integrated foot pump to make inflation and deflation easy and intuitive.

The NEMO Cosmo Air inflatable pad is available in 20 Regular (72" x 20"), 25 Long (76" x 25") and 30 XL (80" x 30") size options. All Cosmo Air pads come with a stuff sack, compression strap and repair patches.

  • Integrated foot pump
  • Lateral I-beam baffles allow for a smooth sleeping surface
  • Includes stuff sack, compression strap and repair patches

Great in certain areas, comfort not so great
Reviewed by Noah K. - January 24, 2016

Likes: Deflates quickly, rolls quickly, packs rather small. I have tried tons of pads. 30 wide is for sure the best as far as width, but no more comfortable than other pads. Dump valve is amazing.

Dislikes: Lack of comfort, heavy, foot pump doesn't exactly air up pad in a few pumps, integrated pillow is just okay. Going back to less expensive, old, yellow foam pad.

Wonderfully comfortable, and wide enough to sleep on your side, bend your legs, etc.
Reviewed by Susan P. - October 3, 2015

Likes: Good support, and high enough to eliminate contact with the ground. I love the width! The built in pump works, and it collapses easily. The fabric surface is not so slick that you constantly slide off. And it's quiet.

Dislikes: The "pillow" is a little bit of a nuisance. Not big enough to really be a pillow, so it sort of shortens the working length of the pad. For me this is not an issue, for a taller person it could be.
