Close The Loop T-Shirt
Winner Award Category Outdoor - Baselayer
Mammut aims to reduce the ecological footprint of its outdoor textile production and contribute to making mountain sports more sustainable. Climbing rope production proportionally causes the highest amount of CO2. In 2018, it accounted for almost 14 percent of the CO2 footprint. This sparked the idea for the «Close The Loop» project with the aim of giving a second life to climbing ropes that are no longer in use.
The challenge was to figure out how the nylon from which the ropes are made could be reused again. Climbers in Switzerland were able to donate their discarded ropes at 50 collection points in climbing gyms, Mammut stores and via a free shipping service. «Close The Loop» was well received by the climbing community as the collected ropes serve as raw material for the production of the «Close The Loop» T-shirt.
The result: 1,000 «Close The Loop» T-shirts made of ECONYL® recycled nylon, produced with 67% less CO2 emissions (compared to traditional production with raw materials from oil). Due to the 3D structure the material dries quickly and is extra comfortable on the skin. To reduce unpleasant odors, the T-shirt is treated with HeiQ Pure technology developed in Switzerland. This helps conserve resources since less washing is required.
Through this project, which was implemented together with the climate protection organization Protect our Winters Switzerland (POW), Mammut was able to demonstrate that circular economy concepts can also be implemented within the outdoor industry.
