The Metolius Quarter Dome is designed for use on shorter walls or as a sub-bag under the main haul bag. They also double as the toughest crag pack youll ever own. Made from the same bombproof Durathane as our full-size haul bags, this bag is 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.
