Sub Zero Merino Wool Lightweight Thermal Walking Socks


Sub Zero Merino Wool Lightweight Thermal Walking Socks are made from a blend of premium Spanish merino wool and polyamide, making them ideal as a summer walking sock or as an extra insulating liner sock in the winter.

The 79% merino content gives you all the benefits of natural wool with extra performance provided by the 21% polyamide. Unlike 100% merino wool socks, these socks offer greater moisture management, are more robust, keep their shape after being washed in a machine, and will be much softer.

The low profile elasticated cuff to these bamboo socks ensures they do not ride down your calf when worn on their own or when under a thicker outer sock. The toe seam is closed using a Lin machine to provide a flat seam that will not rub or irritate the toes.

These lightweight bamboo socks are ideal for use under heavier outer mountain socks as a hygiene layer in the winter, or as a travel sock in hotter climates where odour control and wicking is required.
