Swedish outdoor apparel manufacturers Tierra have been making "clothes for mountains" since 1983. They’ve helped equip the first all-Swedish expedition to Mount Everest and kept Polar explorers, not to mention the Swedish Alpine Mountain Rescue team warm and dry. Now, inspired by the Paris Climate Change Conference and its focus on oil dependency they decided to develop a jacket fully free from fossil based material. The result is Deterra Jacket – the first ever 100% bio-based jacket including materials from castor beans, wool, corn, Tencel, cotton and corozo nuts. The Deterra Jacket has already been honoured with international awards and soon it will be available to customers.
With the Deterra line Tierra wanted to create the most technical jacket possible without using any fossil based material. Erik Isaksson, Head of Product Development at Tierra told us more: “We’re delighted that the jacket attracts such great deal of interest and attention. At Tierra, as individuals we think a lot of how climate-smart we are and can become, and in our job we have the opportunity to create products that help people cut their oil usage.”
The outer fabric is woven of EVO yarn consisting of polyamide made of oil from castor beans. The padding is made of wool from German sheep and the threads of Tencel made from wood pulp cellulose. The buttons are made out of corozo nuts from the tagua palm. The hood is adjusted with a knot instead of a plastic stopper like we’re used to. By reducing the number of different components in the jacket, transportation has also decreased during production.
The Deterra Jacket is a symbol of how technical a garment can be today if it should be fully bio-based. Certainly ighter, more durable, more water resistant and cheaper jackets can be made but then they won’t be 100 % bio-based. The aim for the Swedes is to use the jacket as a platform to talk about new materials and solutions as part of our quest to make technical clothes that are sustainable both for us users and the planet. It’s made a good start, winning the ISPO Award Eco Achievement Apparel 2017/18 and the Sustainable Innovations / Outdoor Industry Award 2017.
