At a scant 10.5 ounces, the Inertia X Wave hits the sweet spot where ultralight meets super comfortable. The 3/4 – length sheds weight for adults who travel light and fast, and is great size for kids. The built-in pillow, integrated side rails, customizable pressure and supportive design elevate comfort, the carefully thought out wave sections cushion side sleepers’ knees, and the tapered lower edge allows legs to lie neutrally. 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.
