The In and Out is the perfect pack for summit-bagging. Most summit packs are glorified stuff sacks with flimsy shoulder straps. But the In and Out is a fully engineered yet featherweight solution. Designed to stuff into its own front pocket, it packs down to the size of a small water bottle. But it has contoured shoulder straps and a sternum strap, is made from 100D mini-ripstop Cordura for tear resistance and is a legitimate carry solution when space is at a premium. In short, this pack will get you in and out!
