Perfect for your next trek to keep neatly organized and ready for action. Two-zone pocket system separates your items from a bladder sized to hold 20 oz. of liquid. Includes an easy-open back panel so it is a breeze to change or clean the bladder and hose. Aero-inspired molded EVA hump works as a third pocket for quick access items. Breathable air-mesh back panel and carbon-fiber looking accents with tone-on-tone Yamaha logo finish off this functional design.
