MSR IN LINE SHUT OFF VALVE

You never want to lose water on the road or during an expedition, which is why it helps to have the MSR In-Line Shut-Off Valve. With a low-profile design and tough HDPE material, this valve is easy to use and extremely convenient from long treks in the backcountry to cycling races in town. It fits most hydration systems and packs thanks to its in-line style, and it has a sleek and lightweight construction, so it resists snagging and dripping.
