Our Regreening efforts

Ethical Manufacturing

The manufacturing process of our products has been carefully curated with a focus on a transparent, people-first approach. By concentrating our efforts on fair working conditions and long, meaningful relationships with our suppliers, we ensure that our manufacturing is as ethical as possible.

Our products are manufactured by Toray in Vietnam, which is a producer for many prominent outdoor brands. The long term relationships we have built with both our suppliers and manufacturers gives us unrivaled control of every step in the supply chain and lets us be highly selective on the partners we work with. Importantly, this allows us to ensure our products are produced in a sustainable manner and the working conditions of workers at every step of the supply chain are not just fair, but great.

Technical Innovation

One way we minimise our impact is through technical innovation. Upon realising the negative impact that nylon has on the environment, combined with the sheer prevalence of nylon usage in the outdoor fashion industry, we set about to innovate something that had never been done before. To create the world’s first 3-layer outdoor jacket made of 100% recycled nylon. Thanks to this innovative creation, Cortazu was selected by a jury panel of 43 judges and received an ISPO Gold Award in 2019.

Recycled components: Another important step in minimizing our impact is the choice of components. The fabric used for the mid-layer is an 100% Recycled Polyester from Toray which is water-resistant and includes a Durable Water Repellent treatment (DWR). The fabric denier is 20D and 100% of the fabric fibers in this product are recycled.
