Trekking socks All season trekker perfectly wicks away moisture and is comfortable on the foot. They combine synthetic and natural fibers (51% Coolmax, 29% Nylon, 10% Tencel (Lyocell) and 10% Stretch Nylon with Lycra) and are made with T3 technology, so they are made of three layers of materials for maximum performance. The socks perfectly dampen the tread and have reinforced stressed areas, which prevents unpleasant bruises. They are very durable and suitable for wearing all year round.
