World's First Bio-Based Jacket: Deterra®

We decided to develop a fossil-free technical jacket


We decided to develop a jacket fully free from fossil based materials. The result is Deterra® Jacket – the first ever 100 % bio-based jacket including materials from castor beans, wool, corn, TENCEL™ Lyocell, cotton and corozo nuts. The Deterra® Jacket has been honoured with international awards, been part of exhibitions, attracted great media attention and is now available to buy at Globetrotter and Naturkompaniet.

"At Tierra, as individuals we think a lot of how climate-smart we are and can become"

With the Deterra® line we wanted to create the most technical jacket possible without using any fossil based material.

– 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, says Erik Blomberg, Head of Product Development at Tierra.

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™ Lyocell 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.

Deterra® Jacket is a symbol of how technical a garment can be today if it should be fully bio-based. We can of course make lighter, more durable, more water resistant and cheaper jackets, but then they won’t be 100 % bio-based.

We will use this 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.
