Outdoor UltraCool Linen Ankle: The most refreshing natural Outdoor sock.

Who hasn't dreamed of the perfect hiking sock that protects your feet from the heat, especially when you're out for the whole day with your family enjoying the hot summer weather? Summer is fun when it is combined with a refreshing environment. That's why Therm-ic wants to be your outdoor partner with summer hiking socks that keep your feet cool.

Linen, natural fibre             

Outdoor UltraCool Linen socks combine high-tech linen and absorbent yarns with an innovative structure to provide perfect moisture management, softness and comfort. Thanks to its smooth surface, linen is breathable, tear-proof, antistatic and odourless. An ideal material to wear in warm weather. These summer socks also feature the incredibly light, elastic and quick-drying Pure-IC organic yarn. They are innovative because of their lightness and quick drying properties.

Highly breathable, these two-colour mixed socks (grey/navy blue), up to ankle height, will also keep your feet dry and protect them from bad odours. Thanks to the Moisture-Vent technology, the fabric has numerous small point pads and a moisture-repellent climate channel system. This ensures that moisture is effectively guided away from the shoe.

Pure-Ic - Biobased High Tech yarn  

Available in different sizes: 35/38 - 39/41 - 42/44 - 45/47
