This mid-calf waterproof sock is insulated with a liner made of expedition-weight double velour Polartec® Power Stretch fleece. The outside layer is knit of nylon/lycra® spandex offering a durable, flexible, stretch covering. In between the two fabric layers is a waterproof MVT membrane. The combination of these three materials provides a very soft, comfy, warm, stretch-to-fit sock suitable for a whole host of cold, wet, nasty outdoor conditions. SealSkinz® socks have a patented fabric structure of three highly engineered layers including a membrane capable of allowing perspiration to escape while not allowing water to penetrate. Each sock is high-pressure tested to make sure there are no leaks.Exclusive Online Only products are products with a catalog number beginning with the letters MP or EP. Example: MP0021.
