Product Highlights

Compact and lightweight, the Osprey Viper 5 hydration pack is ideal for trail running, mountain biking and fast-and-light day hiking. The Viper 5 has the carrying comfort and hydration capacity (2-Liter) needed for technical performance.

Unlike traditional hydration bladders, the Viper 5's 2-Liter Hydraulics reservoir has its own direct-welded "backpanel" that minimizes "barreling" by maintaining a more anatomical shape. Nestled within its own dedicated, externally-accessed compartment, the reservoir is locked securely in place, reducing the sloshing effect that many hydration pack users have come to accept as a necessary evil. An anti-microbial treatment prevents mold and bacteria from building up inside the reservoir.

A spacer mesh backpanel offers lightweight, ventilated support. The padded BioStretch harness and webbing hipbelt offer a secure fit that mirrors your movements during aerobic activities. An adjustable and elastic sternum strap further ensures a stable fit and its magnetic hose attachment strategically secures the hydration system's bite valve.

The Viper 5 has a streamlined storage capacity of 305 cubic inches. A front zippered pocket serves as an additional storage option and a stuff-it pocket on the front of the pack keeps extra layers close at hand. An integrated LidLock clip securely stows a helmet without reducing the Viper 5's storage capacity. A safety light attachment point and reflective graphics provide a measure of safety.

The Osprey Viper 5 hydration pack is available in your choice of color options.
