The Black Diamond Beta Light 45 offers the ultimate blend of durability, lightweight construction, and excellent carrying comfort. Black Diamond has partnered with Challenge Sailcloth to use their Ultra 200 material, which is highly durable and lightweight. This tough fabric, combined with taped seams and a roll-top closure, makes the backpack waterproof and sturdy. A simple Power Mesh stretch pocket and two side pockets provide plenty of external storage options, while the backpack's trail running-inspired shoulder straps offer support and comfort with additional snack pockets and a water bottle storage option. A removable hip belt and a lightweight aluminum frame keep the weight of the backpack down. \n\nChallenge Sailcloth Ultra 200 material is lightweight, tear-resistant, and extremely durable\nTrail running-inspired shoulder straps with extra storage pockets\nRoll-top closure, taped seams, and waterproof fabric\nExternal Power Mesh stretch front pocket and two oversized ripstop side pockets\nRemovable hip belt system\nCompression straps\nInternal sleeve is compatible with hydration systems\nCompatible with Beta Light Satellite 4L Bag for additional storage\nVolume: 45l\nWeight: 890g\n Black Diamond Unisex Beta Light 45 Backpack Storm Gray | Buy Black Diamond Unisex Beta Light 45 Backpack Storm Gray here | Outnorth
