England Rugby is set to embrace a new era with Castore as their kit provider this summer, prematurely ending the agreement with Umbro. The new kits, which won't be unveiled until May after the crucial Six Nations match against France, have sparked initial interest with different neck designs for the men's and women's shirts. The long-term deal is believed to be highly lucrative, valued at over £5m per season. Despite Castore's past mishaps with other teams, the Rugby Football Union is optimistic about the partnership. The 2025 Women's Rugby World Cup will serve as a significant platform for this new collaboration.
