Klymit Inertia X Frame Ultralight Sleeping Pad

When I first saw the Klymit pad I thought it was clever, but wouldn’t provide insulation in the open areas. Then I saw how it allowed your sleeping bag to fill the openings and give more efficiency than other pads while being lighter and more compact. Then I felt how comfortable it was to lay on.

At 9.1 ounces the multiple award winning Inertia X Frame is the world's lightest, most compact, and most advanced full-length camping pad available. Designed with body mapping research, it gives you support and comfort in all the key pressure zones, while eliminating unnecessary material to reduce weight and pack size.

Ideal for 3 season use when used by itself, the Inertia X Frame rolls up to the size of a soda can, and takes only a few breaths to inflate. However, it still offers the adjustable comfort through the use of a dry air pump, which allows you to reach higher pressures than ordinary mouth-inflate pads. You can leave the pump home to save weight if you like a softer pad. The cut out regions of the pad not only reduce the pad's bulk and weight, but is the basis for Klymit's patent pending loft pocket technology. Loft pockets allow the insulation on the bottom of sleeping bags to maintain loft and warmth beneath your body, where it would normally be compacted and useless, while promoting breathability. Use it inside or outside of your bag. Built with ripstop 30d top and coated 75d bottom, the Inertia X Frame is also one of the toughest pads on the market with a burst pressure of over 10 psi.

The Inertia X Frame does not currently claim an R value as it leverages the existing insulation inside your sleeping bag with Loft Pockets (increasing warmth by 40%) to keep you warm and comfy to whatever temperature your sleeping bag is rated based on its Clo value. This pad has been tested to some of the most extreme conditions with surprising warmth and comfort.

Takes just 3 or 4 breaths to inflate. Works great as your backpack frame or stiffener. Size: Inflated – 72 inches long, 18 inches wide. 1 ½ inches thick. Pack size: 2” x 6”. Just 9.1 ounces; dry air pump 1.2 oz., stuff sack .25 ounces, and patch kit .4 oz. (all included). Limited lifetime warranty. Color: High visibility chartreuse green/yellow.
