Another new material is EcoTherm, a fiber from Unifi® that is made with 50% Sorbtek® polyester and 50% Repreve® polyester, which is 100% recycled from plastic bottles. Furthermore, other threads that have been replaced are the standard nylon, which is used to reinforce certain areas, and nylon blended with Lycra, which improves fit, that have been replaced with recycled nylon from fishing nets. Those threads have been used in the T3 Light Hiker, T3 Light Hiker Shorty, T2 Light Hiker, T2 Hiking, T3 Trail Running, T3 Trail Running Padded, T3 Running Precision Fit and T3 Running Padded models that have the word “Eco” added to their names to identify them. They all have the “Ecoengineered” seal that Lorpen has created for the models with recycled thread. The seal is printed on the packaging, which has also been updated to include information in a more visual way that is more understandable and lets the different product lines be classified by color.

This process of innovation is a response to the sustainable production business model followed by the brands that make up the Ternua Group. Lorpen has been moving in that direction for years. Their factory has ISO 14001 environmental certification, the electricity they use comes from renewable sources (solar panels), they don't use chemicals in final products or excess water in their production processes and, because of their location in Etxalar, 95% of the employees can come to work on foot or by bicycle.
