Ortlieb Atrack Hydratation System

If you’re on the move in the great outdoors, you’ll need to drink more to keep yourself properly hydrated. The easiest way to do this is with a hydration system. You can supplement your Atrack backpack, for instance, with a professional hydration system consisting of a specially designed, 2-liter hydration bladder, a removable tube, a bite valve with protective cap and a thermal sleeve that keeps your water cool for hours.
The drinking tube is inserted through the perfectly watertight sealing ring on your backpack.
