Castore has signed a five-year partnership with licensing specialist Apparel brands

The premium sportswear brand said the lifestyle apparel accessories will be developed for men, women and youth, which will be rolled out to key retail partners.

As part of the deal, Apparel Brands will be responsible for developing, manufacturing and distributing the Castore-branded socks and underwear across the UK and Europe.

The retailer said the partnership, which commences in 2026, is a “natural evolution” for the brand as it looks to expand its product offering across high-performance and lifestyle apparel categories.

It said the new accessories will “incorporate Castore’s signature precision and attention to detail, combined with Apparel Brands’ proven retail execution”.

Castore chief commercial officer Danny Downs said: “Our partnership with Apparel Brands is a significant milestone as we continue to evolve our premium apparel offering for customers.

“Socks and underwear are fundamental layers for athletes and everyday consumers alike, and we’re confident that Apparel Brands’ expertise will help us deliver excellence in both innovation and distribution.”

Apparel Brands chief executive Peter Wood said: “Castore represents the very best of British performance innovation, and we are incredibly proud to bring their brand into our portfolio.

“This partnership exemplifies our mission to grow and elevate iconic brands through deep collaboration, category expertise, and global scale. We’re excited to align with Castore’s vision and expand their legacy through world-class socks and underwear collections.”
