At just 258 grams the multiple award winning Inertia X Frame is the world's lightest, most compact, & most advanced full length camping pad available. Designed with body mapping research, it gives you support & comfort in all the key pressure zones, while eliminating unnecessary material to reduce weight & pack size. Ideal for 3 season use when used by itself, the Inertia X Frame rolls up to the size of a drinks can, & takes only a few breaths to inflate. However, it still offers the adjustable comfort through the use of a dry air pump, which means that you can reach higher pressures than ordinary mouth-inflate pads. The cut out regions of the pad not only reduce the pad's bulk & 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 & warmth beneath your body, where it would normally be compacted & useless, while promoting breathability. Built with ripstop 30d top & 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.
