Learning from the limitations of other hydration systems, Osprey have created the Hydraulics, a reservoir which has a lightweight handle to make filling and inserting easier and welded chevron baffles that provide stability and shape, combatting back panel bulges often encountered with flexible reservoirs. The bite valve has a simple turn on/off action and a strong magnetic system which keeps the hose and bite valve in place when not in use but offers hydration you when you need it.Innovative and practical 1.5 Litre Reservoir from OspreyLightweight handle - makes packing the reservoir into your hydration-compatible bag easier, combatting the problems found with more malleable full reservoirs.Welded chevron baffles - stability and shape is provided, stopping back panel bulges and sloshing.180 degree on/off bite valveBPA-FreeQuickConnect included - allows for easy disconnection of the hose when cleaning or replacing.Removable and replaceable hose and bite valveMagnetic lockable bit valve - helps to prevent leakage.Made from an anti-microbial MPE film - this taste-free material can withstand either freezing or boiling water.Litre markings printed on reservoir bodyCapacity: 1.5 litresWeight: 0.16KgRecommended activity - hiking / hill walking / running
