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. 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. 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.
