By combining their popular Stone Duffel 42 with the haul bag-inspired Creek Packs, Black Diamond has created the Crag 40—a climbing pack that's a one-and-done purchase for sport climbers, boulderers and trad climbers who are looking for the ultimate daily driver. With its top-loader design, the Crag 40 provides 40 liters of gear storage, while a full-length side zipper provides easy access. A zippered front flap is perfect for stashing guidebooks, while an internal pocket keeps your keys, wallet and other essentials organized. The Crag 40's top flap acts as a rope strap, so you can conveniently strap your cord to the top.
