Busted seams retire more waders than anything else. The 2S Wader limits that possibility by only having two seams, a body-length seam down the side and another that runs from below the zipper and up your back. We furthered that "less is more" approach by removing excess fabric that's prone to catching on the edges of boats and pit blinds. The 4-layer laminate blocks out all forms of moisture, but lets water vapor escape so things don't get swampy when temperature or output increases. The boot construction and face fabric are more than tough enough for run-ins with sunken trees and busting sheets of ice. Years of testing were aimed at delivering the one thing we all want, waders that last -- the 2S Wader.
