When you're heading out on a long training run or an all-day mountain bike ride, carry your water, snacks and lightweight windbreaker in the Ultimate Direction Wink Hydration pack for women. This low-profile, hydration backpack is specifically designed for women, with a shorter torso length, a narrower neckline, increased padding and ‘S' shaped shoulder straps. It includes a 70 oz hydration bladder with a HyperFlow bite valve to help quench your thirst when you're training on remote mountain trails. Two front multi-use pockets make a great place to stash maps, snacks, a lightweight layer, and your phone or camera.
