Great for saving space on my motorcycle.


  • Rolled up size


  • Valve very hard to open

I ride and camp from a motorcycle and bought this to replace my rather large 30" wide Thermarest. It's less than half the size rolled up but even more comfortable.

The built-in pump is nice although the valves can be very difficult to open when new. I made a cover for it and zip my sleeping bag to it, copied Big Agnes's idea.

Manufacturer's Description

The Cosmo series of pads take inflatable comfort to another level. Cosmo Air is a lightweight sleeping pad with a built-in foot pump. This pad has a generous 3” thickness, but weighs less than 2 lbs, making it ideal for backpacking. Horizontal I-beam baffles create a flatter sleeping pad surface and eliminate any bouncy feel when inflated. Horizontal baffles also tend to support body contours better than vertical baffles since the sleeping pad resists radially folding around the body’s longitudinal axis.

Cosmo Insulated uses a thin layer of polyurethane foam welded to the inner surface of the pad to stop convective currents and create a very consistent and even insulation.

The NEMO Cosmo Insulated Sleeping Pad might be a tad heavier than some ultralight options, but the extra ounces are worth double the comfort and ease. Like other non-self inflating pads, the Cosmo Insulated Sleeping Pad offers an astounding 3-inch platform while packing down to the size of a water bottle. The Cosmo breaks away from the pack by offering a raised pillow supplement, a built in foot pump for easy inflation and PrimaLoft(R) insulation to protect you from the chilly ground. Plush 3 inch (7.6 cm) thickness Built in foot pump for quick and easy inflation Raised portion at the head end to supplement your pillow PrimaLoft(R) insulation keeps you warm even when ground temperatures dip below freezing Horizontal baffles run perpendicular to your arms and legs, making their contours barely noticeable Durable 75D PU Polyester fabrics are supple, quiet and easy to deflate Includes stuff sack, compression strap, and repair patches

Whoever thought backpacking in winter was a good idea must have had the Nemo Equipment Inc. Cosmo Insulated Sleep Pad to keep them nice and comfortable while they slept. Nemo added a layer of PrimaLoft insulation in the durable yet plush polyester shell in order to keep you warmer and cozier than conventional sleeping pads. Even though it stuffs down to about the size of a Jetboil stove, this pad's lateral I-beam baffles raise up to about 3 inches in order to keep you off the bumpy ground throughout the night. These baffles also offer more support and stability than most conventional sleeping pads, and the pad provides a pillow baffle for extra support at your head that doesn't add any weight whatsoever. An integrated foot pump lets your leg do all the work involved with inflating instead of your lungs. When you're breaking down camp for a long hike, stuff this pad in its included stuff sack so you can minimize the amount of space it takes up in your pack.
