Ortlieb Atrack Hydration System

While the system is designed to integrate seamlessly with Ortlieb's Atrack packs, its standard design allows it to function as a standalone reservoir in many other outdoor packs that feature a dedicated hydration sleeve and hose routing port.

The included thermal sleeve is designed to insulate the bladder, keeping your water cool for several hours during active use. While it won't keep ice frozen all day like a vacuum-insulated bottle, it significantly delays warming compared to standard, non-insulated reservoirs.

The bite valve includes a protective cap to maintain hygiene, but it relies on the pressure-sensitive bite mechanism to control flow. It is engineered to be leak-proof during normal use, though we recommend ensuring the tube is routed properly to avoid accidental pressure.

Yes, the system is designed for straightforward maintenance. The tube and bite valve are removable, allowing you to clean the components individually and ensure the reservoir dries completely to prevent mold buildup.

The Atrack Hydration-System weighs 9.9 ounces. It is built for durability, so while it isn't the lightest ultralight option on the market, it offers a robust, leak-proof construction that holds up well to rugged backcountry use.
