The multiple award winning Klymit 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, the Inertia X Frame rolls up to the size of a Coke 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-inflatable pads. Built with ripstop 30d top and coated 75d bottom, the Inertia X Frame is also one of the toughest pads on the market. The cut-out regions of the pad not only reduce the pad's bulk and weight, but are the basis for the patent pending Loft Pocket Technology. Whether you place your pad underneath or inside of your sleeping bag, 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. Loft Pockets also promote breathability. Simply put, you can always sleep in any condition to which the sleeping bag is rated on any of our camping pads with Loft Pocket Technology.
