Osprey know the need for hydration when riding and have equipped the Viper 3 Hydration Pack with an integrated 2.5L Hydraulics™ LT Reservoir, accessed via an assymetric zip for simplistic refilling and 2 chevron baffles to maintain shape, resulting in efficient drinking capability. Osprey have also placed a magnet on the sternum strap and bite valve, securing the hose to the pack when not used and allowing it to be easily accessed when needed.
For long-term comfort, the Viper 3 features a ventilated AirScape™ back panel with BioStretch™ harness evenly distributes airflow throughout the back, especially in warmer conditions whilst offering unrestricted flexibility for movement.
Additional features of the Viper 3 include Osprey's unique LidLock™ technology which creates a secure attachment for helmets, internal compartments to store gear and bike tools and compression straps to push down bulkier loads.
Osprey have finished the Viper 3 with reflective graphics and an LED light attachment, making it safe for you to ride long into the night.
