Performance beyond expectation

Castore has been created to bring a new level of performance to men’s sportswear. We are the world’s first premium sportswear brand specifically for men, targeting only the most discerning athletes who value the attention to detail and precision performance features that underpin all garments. The Castore brand DNA lies in an unrelenting focus on technical innovation to create the most advanced products for those individuals who simply cannot settle for second best.


Our mission is to build the lightest, most durable, highest performing sportswear in the market and to achieve this we test products the hard way. All garments have been tested on elite athletes to ensure they excel at the highest level, worn for 100 consecutive days before being approved for full production. We leave no stone unturned in our search for performance enhancement and work only with the very best partners to push the boundaries of sportswear innovation and give our athletes an edge.


Castore was founded by brothers Tom and Phil Beahon at the ages of 26 and 23 respectively. Both come from professional sporting backgrounds and these experiences have given them a deep appreciation of what serious athletes want from their sportswear which has been key when developing the performance enhancing features prevalent in all Castore garments. Their passion for performance enhancement underpins everything that the Castore brand represents.

For a long time, both as athletes and as sportswear customers, the brothers have been frustrated at the
 lack of high quality sportswear available to men, where the market remains dominated by a small number of global mass-market brands. We are passionate about creating the highest performing technical sportswear available anywhere in the world and redefining the market for the most serious athletes.

The founding vision of Castore is based on a single objective – to build a proudly British sportswear brand that competes on the world stage with the mass-market focussed global brands.

British brands lead the world in so many different areas, whether in fashion, technology, or sport itself and our goal is for Castore to contribute to this rich heritage by becoming the number one premium sportswear brand for men.

Our DNA is British, our ambition is global
