Product description
When all you need for a morning on the trails is a few small snacks and plenty of water, shoulder the Osprey Viper 5 Hydration Pack before heading out the door. The two-liter Hydraulics Reservoir  is contoured to match the profile of the AirScape back panel for improved balance and less sloshing while the well-ventilated BioStretch harness ensures you stay comfy after breaking a sweat.

  • AirScape back panel provides cushion and ventilation for trail runs and cross country rides
  • BioStretch ventilated harness features EVA foam padding and spacer mesh for next-to-skin comfort
  • 20mm webbing hip-belt keeps the pack balanced and in place out on the trail
  • Small pack size holds a few snacks or a compressible windbreaker
  • Separate hydration sleeve provides quick access to the reservoir
  • Two-liter Hydraulics Reservoir features a HydroStatic backer plate that maintains a low-and-wide profile, preventing interference with your pack's suspension
  • Reservoir is made from metallocene PE material that is exceptionally strong, taste-free, and BPA- and PVC-free
  • LidLock clip allows you to quickly attach your helmet when not in use
  • Main compartment has pump-specific sleeves
  • Top zippered pocket has a soft embossed fabric for stowing sunglasses and electronics
  • Magnetic sternum buckle pairs with the magnetic bite valve to keep the hose secure while riding
