These Sealskinz socks aren't just made, they're engineered. Using Aqua Dynamic Design, they're windproof, waterproof, and utilize StretchDry techology for all-year and all-weather performance.
Two layers of material make this happen. The outer layer of these merino wool socks is made from a blend of 87% nylon and 13% elastene. This means they're durable and lightweight. But the inner layer, with its StretchDry hydrophilic membrane, is where the sock magic happens. Made from a predominantly Merino wool blend, this waterproof membrane blocks water from getting in while still allowing smaller sweat droplets to pass through. This makes these grey socks waterproof, but where it tops most other waterproof membranes is the fact that it's also stretchable.
The StretchDry technology means these waterproof socks will not only keep your feet dry, they'll also be supremely comfortable. In addition, elasticated ankle & insteps offer support and a comfortable fit. Wear them hiking, wear them to your favorite outdoor music festival, wear them anywhere--these are sure to keep your feet happy.
