Camelbak Women's Annadel 50 oz:
The low-profile design and women's-specific fit of the CamelBak Women's Annadel Trailrunning Pack work well for trail runs and bike rides. This pack carries 1.5-liters of water in an insulated reservoir pocket and holds your keys, small sunscreen tubes, and lip balm in a front zippered pocket. The short torso length and curved, soft shoulder straps sit comfortably as you dash down the trail. Since you don't want water leaking out the tube, CamelBak gave this pack an ergonomic HydroLock valve.
