In the Fall Winter 2021-2022 collection, Lorpen, the domestic and international outdoor socks brand from the US, has renovated the Polartec T3+ range, designed for extreme cold. In the new model, Lorpen has put Primaloft in the toes into the entire sole and heel, which provides a lot more insulation than the previous version. It also has a trendier design.

One of the highlights in this segment is the Polartec trekking expedition socks that have an anatomical design that’s different for the left and right feet and that has three layers of textiles on the foot made up of two layers of Polartec Power Stretch multi-elastic textile and an insulating layer in between with Primaloft fibre, Lorpen said in a media statement.

The technicity and design of these socks are backed up by the know-how of the brand, which has been based in Etxalar, a small village very close to the Pyrenees, for more than 30 years. Lorpen manufactures all their socks there and then distributes all around the world.

The brand is a pioneer in developing in-house cutting-edge technology for their products, (for example T3 technology which was a turning point in the industry), because it was the first brand to use three different layers of thread in a single sock. That put the brand at the summit of this market niche and they’re currently the undisputed leaders of their segment, according to Lorpen.

They were also pioneers in using flat seems in the toe with their stitch by stitch sewing, which is something only the brand can do at their plant in Etxalar. Specialising in just one product and the passion they make their socks with, where craft and innovation are mixed, means they’re the brand chosen by the most demanding athletes looking for the best performance. That is because Lorpen socks provide transpirability, protection, and maximum compression to guarantee cooler and drier feet than when you wear other socks.
