High-energy activity requires keeping hydrated. The Osprey Viper 13 and integrated 3 litre Hydraulics™ reservoir ensures that you can carry all the required gear and liquid to perform your best. The reservoir is accessed via an asymmetric zip for quick and easy refills. The reservoir incorporates a unique hydrostatic plate that maintains an anatomical shape but also keeps water pressure high for a smooth delivery of water. Osprey packs evoke the early pioneering spirit of daily adventure, from the highest mountains to the remotest islands and everywhere in between.
