Yeah, you could hit the gym, stop shotgunning bear claws, or even leave the six pack out of your backpack to save weight, but where's the fun in that' If you really want to shave some serious pack weight, get the Klymit Inertia X Frame sleeping pad. Weighing well under a pound, the Inertia X won't weigh you down, and it packs down to about the same size of a 12oz can, so you'd might as well throw an actual can in your pack, just for the sake of symmetry.The unique design of the Inertia X Frame eliminates needless areas through a body map design that maintains comfort, while making it the lightest full length mat on the market. The gaps in the mat not only save weight, but also act as loft pockets, enabling your sleeping pad to loft more efficiently, resulting in increased warmth. The pad can be inflated with 3 5 quick breaths, or firmed up a bit with the included Dry Air pump, which weighs just about two ounces. The Inertia X Frame also comes with a stuff sack and patch kit for when you need to make repairs in the field.
