To briefly introduce ourselves, we are passionate skiers with an extensive background in clothing production, fashion, and entrepreneurship. We started out with one goal: to create premium sustainable clothing at unprecedented value. As it turned out, a lot of people were looking for an outdoor brand that does things a little differently.
Within the first two years our products were delivered to over 60 countries. As a result, our technical clothing has been worn in environments such as the Himalayas and the Rocky Mountains, but also in cities such as New York and Tokyo. Since the creation of Cortazu in 2017, we have quickly grown and are now a humble team of ~10 people headquartered in the bustling central European hub of Amsterdam.
