From a kitchen table in Liverpool, England, to the dressing rooms of some of the world's biggest sports teams, Castore is one of the fastest growing premium sportswear brands on the planet.

Founded in 2015 by brothers Tom and Phil Beahon, both former professional athletes. Castore was built on grit, obsession and a bit of a chip on the shoulder.

With no fashion experience, no contacts, no outside investment – the brothers remortgaged, their parents' home, lived off just a thousand pounds a month and packed boxes late into the night. Their mission - to build a British challenger to the global sportsweargiants Nike and Adidas - a brand that blends high athletic performance gear with the sophistication of luxury fashion.

Fast forward almost a decade and Castore is rewriting the rules of the industry. They've developed proprietary fabrics, run a fully integrated design to distribution platform, and perhaps most disruptively, ripped up the old team apparel playbook, forging deep digital first partnerships with elite teams in cricket, rugby, football, and Formula One.
