Klymit and granite gear shows us that tough packs dont have to be heavy themselves. Granite Gear's Vapor Current Crown 60 pack uses Klymit's Airbeam Technology, which is an inflatable frame that provides support for the sub 2-pound pack to carry up to 45 pounds of load comfortably. It also features ventilation channels molded into the cushy back pad to keep you cool; built in stretch mesh pocket at the shoulder strap; a lot of padding on the belt and shoulder straps; and more. This pack is said to have helped hiker Shawn Foray to beat the previous Colorado trail record by an impressive 3 days.
