Certified B Corp

We exist to drive positive change for our planet. We aim to use our business, community, and creativity to do good. We're proud to say Cortazu is the first Dutch outdoor brand to get B-Corp Certified.

We as a business minimise the impact we have on the planet and reduce our carbon footprint as much as possible.

We focus on technical innovation and recycled components and are highly selective with the partners we work with which allows us to ensure the working conditions of workers are not just fair, but great.

Our Regreening efforts

We're on a mission to re-green 10 Million Square Meters of Land by 2025. So far, we have helped to re-green 7.034.093 m² of land and are on track to reach our goal by 2025 together with our community.

Cortazu doesn't exist just to sell outerwear products. We're here to inspire people to create their own adventures while supporting the world around us.

That's why we partnered up with Justdiggit and started to cool down the planet. If we can warm up the earth, we can also cool it down.

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. Our current range of products are all composed of 52 recycled materials and we are currently working on advancing the technology even further so we can bring the above-mentioned 100% recycled version to the market.

Best of the best!

This is my second purchase of Mountain hard shell. The first one was bought from Kickstarter 3 years ago. I have been using Cortazu set of three (mid layer puffer and fleece) for outdoor activities and city life. Did Kilimanjaro in 2021. Outstanding design and quality. Different from another hi-end gear for skiing and outdoor activities.

Skiën en vrije tijd

1.93 88kg maat L. Onderjas met extra laagjes past er goed onder. Ik heb relatief lange armen, maar past heel goed. Ook niet te kort qua lengte van de jas. Tevreden!
