Built for cold, high-altitude pursuits.
Outer – Extra-durable nylon exterior, with 4-way stretch for an optimal fit.
Mid-Section – Aquasealz™ waterproof membrane releases moisture vapour from inside the sock.
Interior – Premium merino wool, with terry-loop knitting for extra comfort and sweat-wicking. Natural antimicrobial properties, stopping growth of odour-causing bacteria.
A seamless construction, with elastic support on the ankle, providing a close fit.
