Horizon Performance Extreme Sock

£30.00 RRP £35.00

Extreme temperatures require extreme socks. The Horizon Performance Extreme Sock is an over-calf length Primaloft® / Merino wool sock ideal for freezing conditions whether on expeditions or mountaineering. Primaloft's performance fabrics and yarns are primarily designed for next-to-skin comfort to suit a range of activities and combat the harshest conditions. The Primaloft® Silver Merino Wool blend offers an antibacterial finish, enhanced warmth, superior comfort and unrivalled performance. To ensure this sock is as good as it can be, we've added Isolfil polypropylene to wick away moisture keeping the feet dry and hard wearing Cordura in the vulnerable heel and toe areas. With elastic grip sections and Lycra the sock retains its shape even after drip drying. The result is the very best sub zero expedition and mountaineering sock that money can buy.

  • Great service and would recommend

  • Simple and quick process in placing my order followed by a very prompt despatch, though Royal Mail did let the side down somewhat because when using the tracking facility I discovered that my order was just sitting at the local delivery office for an entire day before actually delivering it. (and the excuse given on the Royal Mail website for not delivering the package as scheduled was due to my address being inaccessible, which was a total fabrication!!!)
