  • Osprey Viper 13

    For sustained, high-energy activity, you need to stay hydrated. That's why Osprey's Viper 13 backpack comes equipped with an integrated 2.5L Hydraulics™ LT Reservoir, so you can push yourself to the limit. The reservoir is accessed via an asymmetric zip for quick and easy refills and incorporates 2 chevron welded baffles to help it maintain its shape when full and limit water sloshing.

    User Friendly and Comfortable

    The common issue of a 'wandering hose' has been solved by placing a magnet in the pack sternum strap and bite valve. This holds everything neatly in place when not needed, yet ensures quick and easy access when it is. The ventilated AirScape™ back panel and BioStretch™ harness keep you cool in hot conditions whilst still offering flexibility for movement without restriction.

    Highly Practical

    Osprey's unique LidLock™ attachment provides a quick and secure attachment point for your helmet without taking up space inside your pack. Gear and bike tools are easily organised and carried within the quick access internal compartments. A removable webbing hipbelt allows you to shed extra weight if you're really counting the grams. There's even reflective graphics and LED light attachment help to keep you visible for when the weather turns or night falls.
