The Half Dome is an incredibly tough haul bag. It is made of Durathane, which is 10 times more abrasion-resistant than the vinyl-coated nylon used in most other haul bags! The main seam is RF welded, creating a leak-proof seal that is stronger than the fabric itself. In addition, all the structural stitching is covered with 3" webbing and then re-stitched for maximum durability. This bag is well-padded, with an ergonomically-cut suspension system that tucks away in seconds for hauling. It features a river-bag-tyle closure and custom aluminum closure buckles that are virtually indestructible. The Half Dome has dual top-compression straps, offset haul points and a drain hole. It has three internal gear loops and a zippered internal pocket in the lid for easy access for small items. Half Dome volume is 7600 cubic inches, or 125 liters.
