This Mid calf high 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 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 ChillBlocker Socks.

Advanced Waterproof Protection
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.

Hand-wash and drip-dry for the greatest longevity. Do not twist or wring. Or machine wash on low temperature and tumble-dry on low. When machine drying, reverse socks halfway through.

Medium: Mens 7-9 Womens 8-10
