Manufacturer Castore

J. Carter Sporting Club Limited (trading as Castore) is a British sportswear and sportswear manufacturer, headquartered in Manchester, England. The Company's products are sold in over 50 countries around the world and have sponsorship agreements with association football teams, cricket teams, rugby union teams, Formula 1 teams and players of tennis.

The company was founded in 2015 by brothers Thomas (born September 1989) and Philip Beahon (born November 1992) when they were 25 and 22 years old, respectively. Tom had been a professional youth football player for Tranmere Rovers between the ages of 17 and 21 before spending time at Jerez Industrial in Spain and attending the Glenn Hoddle Academy. Phil played semi-professional cricket for Cheshire and Lancashire Cricket Clubs.

The couple left their playing careers in 2013 and moved to London to work in finance with the aim of raising money for their sportswear business; Tom worked at Lloyds Bank and Phil for Deloitte. While in London, they began their market research by interviewing customers of high-end gyms and recruiting a number of prolific investors from the fashion and sports industries. Castore launched online in 2016. In 2019, Forbes listed the pair on its "30 Under 30" list.
