This Mid-calf-high waterproof sock is insulated with a liner made of expedition-weight double velour Polartec(R) Power Stretch(TM) fleece (7.3 oz. per square yard). The outside layer is knit of nylon/lycra(R) spandex offering a durable, flexible, stretch covering. In between the two fabric layers is our waterproof MVT membrane. These three layers are securely bonded together throughout. This combination of materials provides a very soft, comfy, warm, stretch-to-fit sock suitable for a whole host of cold, wet, nasty outdoor conditions. If you are outside in cold weather doing such activities as hunting, ice fishing, skiing, boating, and military service - you will be pleased with our New SealSkinz(R) ChillBlocker(TM) items.
