When you’re squeezing in a quick ride after work, Osprey’s Viper 3 is the perfect size. The suspension is designed for moving light and fast: A foam framesheet spreads weight across a ventilated mesh backpanel for lightweight comfort. The BioStretch™ shoulder harness provides a contoured fit and the webbing hipbelt is removable to shave ounces. If you end up carrying extra weight, top compression straps lend extra load stability.
Access gear in the main compartment via a zippered front panel. You can slip small items into the harness pocket or stash a layer in the front fabric shove-it pocket for quick access.
Bike-friendly features include a Hydraulics™ LT 2.5 liter reservoir with magnetic bite valve retention, internal bike pump storage loops, and Osprey’s innovative LidLock™ helmet attachment system.
