This is the type of sock you can throw in the wash along with the rest of your gear. No need to line dry or wash with special detergents. Wet feet can lead to all sorts of not-so-good things outdoors, including numbness, blisters, and frostbite. Our Waterproof Cold Weather Mids will keep you dry and warm in leaky waders, through stream crossings, and in rain, snow, and mud. Designed to Keep You Warm and Dry Our cold weather socks are crafted using a three-layer bonded construction that combines a 100% waterproof hydrophilic membrane with a premium Merino wool interior for warmth and sweat-wicking, and a durable nylon blend exterior with 4-way stretch for great fit and wearability. An Added Layer of Warmth Designed with warmth in mind these socks are constructed with the finest Merino wool and an added a layer of terry-loop stitching. This loop stitching actually traps heat within the air pockets keeping you warmer when you're in the coldest conditions. Ideal for a Wide Range of Activities The perfect mix of waterproofness and breathability, waterproof socks are ideal for keeping your feet dry and warm while cycling, hunting, commuting, working outside, fishing, or hiking. Built for comfort and blister prevention Designed with a seamless construction including hand-linked flat toe seams and the addition of elastic support on the ankle, heel and instep, you won't notice the seams but will definitely notice the extra comfort and fit. Handmade & Hand Tested Exclusively handmade in the UK to our unrelenting standards and attention to detail, every single sock is hand-tested for waterproofness.
