The all-new G3Z Pro sets the benchmark for guide-caliber wader performance. Built in Bozeman, Montana, with an entirely new GORE-TEX textile featuring the most pinhole puncture-resistant 4-layer wader fabric we’ve ever tested (60% greater than the previous G3), it’s designed for anglers and guides who spend more days on the water than off. The G3Z Pro combines legendary Simms reliability, exceptional durability, and uncompromising waterproof-breathable performance in our most capable G3 ever.
