This Wildfish Chest Wader is built from a tough Nylon/PVC construction. Taped and heat-treated seams ensure a smooth and 100% waterproof finish. Adjustable, quick release clips allow you to tailor the fit of the waders while still ensuring enough space for additional clothing and unrestricted movement. It also has a handy chest pocket. The integrated boot design with cleated sole provides additional grip against slippery surfaces making the waders ideal for all surfaces. Wildfish Waders come in 7 sizes which are measured by boot size, for example a size 10 Wader refers to size 10 shoe size.
