British sportswear brand Castore has signed a multi-year kit partnership with the Football Association of Ireland (FAI).

The deal makes Castore the official kit supplier and retail partner of the FAI, with the brand to produce match kits for the Republic of Ireland's national teams. It begins on March 20 with the reveal of the new home kit.

The deal also involves Castore investing in the FAI ecommerce platform.

It is Castore's first deal sponsoring a national soccer team, although the brand has a host of deals in place with club sides, variously including Feyenoord, Genoa, Athletic Bilbao, and Aston Villa.

The Castore deal follows the announcement of new crests for both the FAI and its national teams as part of a rebrand.

Jonathan Hill, chief executive of the FAI, said: “This is an exciting time for the Association as we announce a new kit partner, a new shirt, and a new crest for our international teams. Importantly, this is a significant commercial deal for the Association which helps us in our core strategic objective of creating a more stable financial base for the business and for the game as a whole.”

Castore founder Tom Beahon added: "We are extraordinarily proud that Castore will have the honor of producing the iconic Ireland jersey until 2028 and we fully understand the responsibility we have to carry on that tradition and history.

"Along with our financial commitment to the FAI, we will invest significantly into the FAI’s e-commerce infrastructure, providing a best-in-class online shop for Ireland fans home and abroad and will align with the FAI’s strategic ambition to embrace digital technologies to better connect with all fans.”
