The Inertia XL is the lightest, most compact oversized pad available. Packed with comfort features – a built in pillow, a wider sleeping platform, customizable pressure and support – it still weighs in at only 14.1 ounces and packs down to soda can size. Deep welds up the thermal efficiency, and patent-pending Loft Pocket Technology positions the chambers to maximize your sleeping bag’s performance while minimizing pad weight.
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.
Empty spaces between the chambers serve as expansion zones that allow your sleeping bag to fully loft beneath you, maximizing its thermal performance.
