High-tech waterproof, windproof and breathable accessories that really do work, and do so equally well sailing in the Solent, or on rainy days on the High Street! Close-fitting and waterproof all the way up, the tops of our DexShell mid-calf waterproof socks also incorporate DexShell's patented in-cuff seal system which significantly reduces the ability of splashed water to seep into the top. The fabric has been designed to stretch both lengthways as well as widthways for a supremely comfortable fit. The inner layer is 40% Merino wool for warmth.
