Review on High-Flow Helix Valve Kit with Soft Bite for Full Flow - Easy QMT Quick Connect Mechanism - Dirt Shield for Dust and Pollution Protection by Richard Edwar

I've been using the first generation of this product for years and I swear I use the original zip bags, I just like them more than the camel bags because they're so much easier to clean. The bite valves are great too and now have a built in flow stop feature and come with a dirt cap if that's something you like. Also very easy to install.
