A technology that allows us to combine different numbers of layers in different areas of the same sock, as required by the activity.


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


Merino Wool

Due to the long length and short diameter of the fiber, Merino sheep's wool creates a softer yarn with a finer loop that is softer to the touch than wool from other species of sheep. The fiber's core is hydrophilic (water retaining) and breathable. Since it retains heat even when damp, it is the fiber used in the middle layer of our T3 socks and the main fiber in our T2 socks for use in colder temperatures.

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 Cycled 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.

Stretch Nylon with Lycra

Lycra is a synthetic elastane fiber that can stretch up to six times its length and go back to its original state again and again. Its strategic placement in the outer layer of Lorpen socks guarantees a long life for our socks. Along with Nylon, Lycra is characterized by its strength and cushioning capacity.
