Super Seam® Technology replaces standard stitches with a powerful super adhesive, creating stronger seams that greatly reduce the chances of a leak. These stitchless seams are 32% stronger than conventional waders and 49% stronger than a leading competitor's. It helps us build a lighter, more flexible and leakproof wader that you'll find super-comfortable. Vibram Idrogrip outsole provides exceptional grip on wet rocks, slime and moss.
