Optimal fit and comfort in a super light mid-size trail pack
Osprey's Viper 13 Hydration Pack gives you ample storage space without being bulky or awkward. This pack boasts 13 liters of storage room, perfect for a whole day on the trail. Surprisingly light, and well organized, this pack has become an essential for many riders. Slippage and shaking are reduced thanks to their innovative BioStretch harness and hipbelt, while comfort is never sacrificed. The hydration bladder features specially designed baffles to reduce liquid movement and maintain stability at high speed. Convenience comes in the form of a zippered hydration sleeve, allowing fast and efficient refills. A magnetic disc on the sternum strap secures the hose in an easily accessible location.
Compression straps on the side of the pack help to stabilize the load, keeping the pack compact. You can access the main compartment via the front zipper panel. Other pockets include a padded sunglass compartment, dual side mesh pockets, and a stretch mesh harness pocket that can be easily used to stash layers. No matter what you carry, your load is spread evenly across a ventilated mesh back panel, giving you comfort all day without sweat building up. The exterior of the pack also includes a LidLock helmet clamp, and a blinker light attachment. On the inside, you'll find well organized compartments, and bike pump specific storage loops. A 2.5 liter bladder is included, and the pack's total volume is 9 liters. At a total weight of 1.28 lbs, the Viper 13 is exceedingly light for its size.
