ORTLIEB Atrack Hydration System 2 Litre

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.
