Fox's Oasis Hydration Pack is great for after-work singletrack sessions and long weekend rides. Its large-mouth 100-ounce reservoir keeps you hydrated and is easy to clean, while the pack's large cargo capacity lets you bring your riding essentials on all your excursions. Load-stabilizing compression straps keep the pack from jostling on your back on rugged, technical terrain. Plus, you've got cinch straps that can handle full face helmets and shock cords on the bottom to strap your armor down for the long climb up. There's also a sunglasses/MP3 player pocket with internal wire routing.
