The Thule UpTake 12L Hydration Pack is a hydration pack for mountain biking and hiking. Carry the essentials such as extra layers, a rain shell, bike tools, and snacks, while the included 2.5L HydraPak Reservoir makes hydration easy when you're on the move. The hands-free ReTrakt magnetic hose return system allows for a quick sip, then it falls right back into place so it's out of the way while you're pumping the pedals or hiking along.
