The Deuter Futura 22 is a comfortable 22-liter, unisex daypack renowned for its Deuter Aircomfort mesh back system for maximum breathability, an advanced suspension system, plus plenty of pockets and attachment straps. It weighs about 2 lbs 12 oz. Features include: - Ventilated Aircomfort system so air can flow between the pack and your back - Anatomically shaped, soft padded waist belt and padded hip fins - Ergonomic AirMesh shoulder straps to keep you cool and reduce sweat under your straps - Length-adjustable shoulder straps - Zipped access at the top of the pack to the main compartment - Zipped front pocket - Internal "valuables" pockets - 2 exterior side stretch mesh bottle pockets - Stowaway rain cover - Hydration bladder compatible, so you can pack in fluids without lugging around water bottles - 22 liter capacity Made of Super-Polytex and nylon ripstop.
