The T3 Heavy Trekker is a reinforced sock throughout with a full cushion and Primaloft ECO for maximum protection on outings at low temperatures. Ideal for Autumn-Winter hiking and mountaineering.

T3 Technology: Exclusive technology with three differentiated layers of yarn, allowing for peak performance from each type of yarn and providing maximum benefits for athletes.

Primaloft ECO: Polyester yarn developed by PrimaLoft® (number 1 in the world in artificial thermal insulation for technical garments). It is a soft, thermally insulating, hydrophobic fiber that wicks away and does not absorb moisture. It is currently made with 70% of its contents coming from recycled resources like plastic bottles.

Red-Cylced Nylon: Red-Cycled Nylon yarn is 100% made with fish nets whose useful life in the fishing industry has come to an end. Instead of becoming a hazard at the bottom of the ocean or garbage elsewhere, they are recycled into a new nylon yarn. This continuous fiber yarn is characterized by its strength and cushioning capacity. This is the fiber that is most resistant to wear and tear.
