The Extreme Primaloft® / Merino wool sock is the ultimate expedition sock for trekkers & mountaineers who take their kit selection seriously.
Primaloft’s performance fabrics & yarns are primarily designed for next-to-skin comfort to suit a range of activities and combat the harshest conditions. These Extreme socks are made using a Primaloft® Silver Merino Wool blend which offers an antibacterial finish, enhanced warmth, superior comfort and unrivalled performance. If that wasn't enough, we have added polypropylene in the sole to wick away moisture keeping the feet dry and hard wearing Cordura in the vulnerable heel and toe areas. The result is the very best sock that money can buy.
