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 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.
One of the great benefits of owning an Osprey product is their All Mighty Guarantee, which offers to repair any damaged or defected goods for any reason free of charge no matter when it was purchased so you can go on your adventures worry-free.

I really like the details of Osprey pack designs. The magnetic bite valve clip is brilliant. The bladder on this pack is in it's own compartment with an excellent house route zippered into the harness very slick. The bladder uses a fold and clip design so it is easy to fill versus a screw cap or even worse a recessed screw cap! I have not had a single problem with leaking or filling the bladder. I didn't want too big of a pack but needed some room to carry all my daily mountain ride essentials and have a little extra room if I needed a jacket or had to carry an extra tube or just a longer ride and more food. This pack fits the bill. I love the dedicated phone pocket up top (nobody likes a scratched iPhone screen) All in all a great pack I can easily recommend.
