The lightest, most compact, most advanced full-length sleeping pad ever developed, the award-winning Inertia X Frame packs to the size of soda can and weighs a mere 9.1 ounces. The body-mapped design provides comfort and support at key pressure points while eliminating unnecessary material that can add weight and bulk. It inflates quickly with just a few breaths or with an optional pump that maximizes air pressure. Built for fast and light three-season backcountry use, the Inertia X has a light, tough 30d ripstop top paired with hardwearing 75d bottom that makes it one of the toughest pads around.
Body Mapping Advanced patterning places chambers only where padding is needed and eliminates them where they are not, allowing us to shed significant weight without sacrificing comfort.
Loft Pockets Empty spaces between the chambers serve as expansion zones that allow your sleeping bag to fully loft beneath you, maximizing its thermal performance.
