Push your downhill bike to the top of mountains with your helmet, hydration reservoir, pump, and more in Osprey's Viper 13 Hydration Pack. Its included Hydraulics LT 2.5L reservoir gives you much-needed water without stopping the ascent, and the LidLock system secures your helmet so it doesn't tumble down the hill once you reach the top. Osprey made this pack with well-ventilated Airscape and BioStretch mesh, and the back panel has an Atlion foam framesheet to enhance stability without interfering your mobility down the mountain.
