Heat and comfort all day for any winter activity. Two different designs in a pack of two pairs. The technical composition offers details on the type of thread and material. The legal composition refers to the net amount of each material. Differences between the two compositions may arise in socks made with more than one material.Specifications:- Cushioned: Sole- Season: Winter- Technical composition: 78% Merino Wool, 18% Red-Cycled nylon, 4% Stretch Nylon with Lycra- Legal composition: 78% Wool, 21% Polyamide, 1% ElastaneTechnology: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.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.
