Equip your Osprey Hydraulics Reservoir (sold separately) for extreme temperatures with the Insulated Delivery System. The system consistes of an insulated drinking tube and bite valve. A heat reflective closed-cell foam sleeve helps to shield your hydration hose from both heat and cold. A zippered foam pad encloses the bite valve to further ensure that you're able to get to water even when the mercury dips below freezing. An integrated elastic clip keeps the system securely in place while in use.
Note: The Insulated Delivery System is custom designed to retrofit any Osprey Hydraulics Reservoir.
