Polyester yarn developed by Primaloft® (world number one in artificial thermal insulation in technical garments). It is a soft, thermally insulating, hydrophobic fibre that expels and does not absorb moisture, with 70% of the content now made from recycled resources such as plastic bottles.

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.

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.
