The Trekking Ultra Cool Crew from Therm-ic will win you over with their functional and innovative properties. They are ideal for hiking tours on hot days. They have excellent moisture management: the climate channel system removes warm, moist air from the hiking boots to regulate the temperature. Bio-based Pure-IC yarn - made from castor bean seeds and therefore full of performance - ensures that the socks dry quickly and keep you comfortable. The socks have also been given an ecological cooling and anti-odour treatment to prevent odours - so you can wear them for several days without any problems. The heel and toe protection and ergonomic cuff ensure a particularly high level of comfort. If you're looking for the perfect hiking socks for hot days, your search has come to an end with the Trekking Ultra Cool Crew!
