Proven and reliable protection in any weather

Ready to help you take on the coldest and wettest weather, the Waterproof Extreme Cold Weather Mid Length Socks are designed to keep you comfortable and on the move in the most extreme conditions. Waterproof, breathable, and warm, they're an ideal choice when you're at risk of getting wet in snow, ice, mud or rain.

Cold and wet feet can lead to all sorts of not-so-good things outdoors, including numbness, blisters, frostbite, and worse. Our Waterproof Extreme Cold Weather Mids will keep you dry and warm during frigid stream crossings, on blustery cold and rainy days, through icy terrain and deep snow, and even standing in cold leaky waders. With this kind of warm and waterproof protection, you’ll wish you had them sooner -- trust us.

  • Anti-Blister - Prevents friction and rubbing which eliminates blistering

    • Outer: OUTER: 90% Nylon, 10% Elastane

    • Finer than traditional wool with tiny overlapping scales that case each fibre, these scales are hydrophobic (water repellent). Inside it's a different story, the fibre core is hydrophilic (highly absorbant). Merino is therefore a wicking fibre and can absorb and release 10 times more moisture than synthetics. Each fibre can absorb up to one third of its own weight in moisture without feeling clammy or wet to the touch. In our socks and gloves, the moisture is then wicked through the membrane to keep you feeling warm and dry



  • The perfect barrier between you and the most challenging wet weather. Our products are developed in such a way as to give 100% waterproof protection whilst being incredibly breathable and dexterous. Add in varying layers of insulation means we can offer waterproof products for all climates.
