Replacement valve with leak-proof control for Big Zip EVO

　　The Platypus Big Zip EVO Shutoff Valve is a leak-proof valve made specifically for the Big Zip EVO Reservoir. The improved design offers a wider angle for faster water flow, an embossed water droplet icon to indicate when water flow is engaged, and a larger on/off lever for ease of use (even with gloves on). The result is a valve that offers faster water flow and a more intuitive on/off lever. Compatible with the HyFLO Bite Valve (sold separately).
