The Inertia X Frame mat is the lightest and most compact full length sleeping pad available in the world. It incorporates body mapping research to provide comfort and support in the key pressure areas to provide a great sleeping base, but excess material has been removed to ensure it remains as compact and lightweight as possible.
The Inertia X-Frame rolls up to the size of a small can of soft drink, and takes only a few breaths to inflate, but conveniently comes with a small hand pump to allow you to inflate it to higher PSi levels for better support.
The cut-out regions of the pad are for more than just reducing bulk and weight, they are part of Klymit's patent pending Loft Pocket Technology. These cut-out regions allow your down sleeping bag to maintain loft and therefore warmth beneath your body, where normal sleeping pads would normally mean it was compacted underneath you and therefore relatively useless in terms of providing warmth.
