Sun on your face, wind in your hair, and the thirst-quenching Viper on your back.

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.
