Source’s unique valve is quite different from others on the market. There is a mechanism inside the valve that fully opens once the user bites in the valve. The greater the pressure that is exerted on the reservoir the tighter the valve mechanism closes up, thus preventing leaks. The tube assembly is 40 inches long and comes with a braided cover (just like on a climbing rope), A lapel clip is also standard with each valve/tube assembly. Our Valve/tube assembly will fit on most other hydration systems on the market, allowing one to upgrade their old system with ease.
