Outdoor UltraCool Linen Crew: The driest, lightest natural trekking sock

Linen, natural fibre                  

This high trekking sock is part of the new outdoor range from Therm-ic. Whether you need warmth, coolness or simply comfort to enjoy a long walk in the wilderness, Outdoor UltraCool Linen socks also provide you with all the qualities of the natural fibre, linen, combined with the innovative structure of the incredibly light and elastic Pure-ic yarn of organic origin. Indeed, linen is an ideal material to wear in warm weather; it is breathable, odourless and durable. Linen is also cool to the touch and becomes softer with each wash.

These highly breathable mixed socks will give you natural comfort and keep your feet dry and cool. Thanks to the Moisture-Vent technology, the texture of the trekking socks contributes to a good and safe ventilation of the foot without altering its natural stride. Your outdoor shoes will breathe freshness! No more bad odours.
