The Simms Men's G3Z Pro Stockingfoot Waders give serious anglers and guides durable, breathable protection for demanding days chasing trout, steelhead, salmon, and other cold-water species. A TIZIP center-front zipper adds convenient access, while the GORE-TEX fabric package combines waterproof, breathable 3-layer Performance fabric through the upper with rugged 4-layer GORE-TEX PRO across the lower legs and seat for added puncture and abrasion resistance. Two stretch YKK zippered pockets keep fly boxes close at hand, and micro-fleece-lined handwarmer pockets provide warmth and dry faster after wet releases or repeated fly changes. The self-gathering back yoke increases mobility and leaves room for cold-weather layers, while upgraded suspenders improve airflow and comfort and feature opposing buckles for waist-high conversion. Integrated Gravel Guards, front and back leg seams, a low-profile rear belt loop, included neoprene wading belt, and premium compression-resistant neoprene stockingfeet with antimicrobial treatment round out a hardworking setup.
