The Quarter Dome and Sentinel are designed for use on shorter walls or as a sub-bag under the main haul bag. They also double as the toughest crag pack you'll ever own. Made from the same bombproof Durathane™ as our full-size haul bags, these bags are built to take massive abuse. Double layers of Ballistics nylon on top and bottom seal out the weather. For the approach, these bags feature well-padded ergonomically shaped shoulder straps with our custom aluminum buckles, top riser adjustment, and sternum strap, all of which tuck away into a built-in pocket for hauling.
