Through this strategic partnership, product ranges will be created for men, women, and youth, and will be rolled out through key retail partners. Design and collaboration between Castore and Apparel Brands is already underway, ensuring the first collections reflect Castore’s engineering ethos and Apparel Brands’ category expertise from day one.
