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.

We're on a mission to regreen 100 Million Square Meters of Land. So far, we have helped to re-green 10,368,829 m² of land as of 2025 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.

We believe great products start with strong values. That’s why our manufacturing emphasizes transparency, long-term partnerships, and a people-first approach. We prioritize fair working conditions and sustainable practices, backed by our B-Corp certification.

We choose manufacturing partners based on verified social audits, assessing fair wages, safe conditions, reasonable hours, and workers’ rights. This ensures our products meet high ethical standards.

By building lasting relationships with trusted suppliers, we maintain control over our supply chain and work only with those who share our values—delivering outdoor-ready products with minimal environmental impact.

One way we minimize our environmental impact is through technical innovation. When we recognized the harmful effects of polyester on the environment, alongside its widespread use in the outdoor fashion industry, we set out to achieve something unprecedented: the creation of the world’s first 3-layer outdoor jacket made entirely from 100% recycled polyester.

Thanks to this groundbreaking innovation, Cortazu was selected by a panel of 43 judges and awarded the ISPO Gold Award in 2019.

Recycled Components: Another key step in reducing our impact lies in the careful selection of materials. Our current product range incorporates recycled components, and we are actively working to advance our technology even further, aiming to bring a fully 100% recycled version of our products to market.
