The pack uses an internal frame and a weight-bearing waist belt for comfortable load-distribution. A large main compartment, overflow front pocket, two stretch side pockets, and a fleece-lined compartment for your sunglasses or electronics keep you well organized. The pack's compression straps offer incredible stability and its NV back panel makes it comfortable for hours on end. Missing the hydration bladder, but new hose and mouthpiece in tact.
