The Evolution Zip Wader is comprised of a four-layer cloth that is both waterproof and breathable. The seams have been placed outside of the friction zones. YKK zips are used on the two front pockets. These Hydrox Evolution Zip waders are flexible and comfy, with bi-density neoprene liners, a wading belt, and adjustable elastic suspenders. The Zip versions have a T-Zip closing from Germany, which ensures quality and durability.
