Built to keep us warm and dry on the water, Simms' Freestone Z Stockingfoot adds a waterproof center zipper to these popular waders. The 4-layer Toray fabric is rugged to handle overgrown river trails and deliver durable waterproofing for multiple seasons of wading. When nature calls, the convenient TIZIP zipper lets us take a whiz without removing our waders and upper layers, so we don't waste precious fishing time dressing and undressing. In the Simms Stockingfoot series, we don't need to worry about getting wet. All we need to do is slide our wading boots on-and slip the built-in gravel guards over them-and hit the water with our favorite dries or nymphs.
