Lorpen operates in an industry with a spectacular appetite for performance improvement, and it's not reasonable to think that the same yarn with the same old construction is perfect for every temperature or activity (there are some merino sheep out there that would like you to believe this). Their research and development department along with our filed testers all over the world are continually evaluating a wide assortment of socks made from natural, synthetic and blended yarns in a wide range of terrain and environments... and the number of new yarns available to them has never been greater. The groundswell of world wide concern for the environment is changing Lorpen as a company, challenging them to evaluate everything about how they conduct their business, from the yarns they use to the packaging and catalogues they produce - using resources more efficiently, looking for natural sustainable alternatives when they can find them... even evaluating thier yarn suppliers to ensure they too are working towards being more ecologically sensitive is important to Lorpen as a company.
