The Simms Tributary Wader - Men's is a wader for fly fishing. The rivers are teeming and it's time for you to step into the water and cast a line. The waterproof polyester fabric features a 3-layer fabric at the upper and a 4-layer fabric at the lower, providing durability and protection. The shoulder straps are adjustable for dialing in the fit, and the included 38mm wading belt is non-stretch. The stockingfoot style allows for a better fit inside your wading boots and increases comfort on the hike to the river.
