The Eberlestock Warhammer J51 Pack is tough and durable for extended use in rough terrain. Manufactured with 1000D CORDURA Nylon, durability will not be of concern. This pack is designed for efficient, lightweight storage of all hunting accessories. Fitted with a lightweight aluminum frame, the pack maintains the strength of a standard steel frame without the weight. Internal and external sections of MOLLE webbing allow for accessories to be attached for superior organization. Two hydration sleeves fit a 2-liter pouch so you will always have plenty of water on hand. The adjustable shooter" harness is thinner and more flexible to allow for a full range of motion while hunting. To easily carry a firearm, the pack is compatible with several weapon scabbards. Heavy-duty compression straps hold everything together to ensure safe carry of your valuable accessories at all times.
