adidas TERREX, the outdoor focused branch of the sports apparel giant, is partnering up with The Sustainability Workshop (TRW) on a new sustainability-based initiative called “Nothing Left Behind.”

Since 2015, TRW has become a renowned consultant of solutions for different brands thanks to its innovation on sustainability-focused gearwear. With adidas TERREX, the “Nothing Left Behind” initiative focuses on re-engineering worn-out apparel and textiles into upcycled materials for outdoors people by using TRW’s proprietary Renewal System technology.

This partnership was made to highlight adidas’ commitment to extending the life cycle of its products and minimizing waste at the same time.

A range of jackets and pants from this new project were gathered from adidas TERREX athletes as well as employees. The clothes were then repaired and remixed, then returned to the original owners for further testing and evaluation.

While the “Nothing Left Behind” collection is not available to the general public for purchase, outdoor enthusiasts can sign up to enter into an online raffle for a chance to win a signature piece from the custom-made capsule.
