From singletrack to downhill, the Dakine Apex 26L Hydration Pack is the ultimate mountain biking companion. It comes with a three liter Shape Loc hydration reservoir to keep you going all day, with a shoulder strap port and a Plug N Play disconnect system for easy removal and filling. Riding can be a sweaty business, but the Air Channel back panel ventilation keeps cool air moving, and the removable waist belt keeps your gear from bouncing around and throwing off your balance. Dakine hooked the Apex up with a helmet carrying system that can hold full face or trail helmets with equal ease, and itincluded a fleece lined sunglasses and goggle pocket to keep your lenses from getting scratched when you're not wearing them. Internal organization pockets keep your spare tubes, pump, trail maps, and more in order so you don't have to tear apart your whole pack to find what you need.
