The brand has become the official kit supplier to the England rugby league team, the governing body and the sport’s match officials for the next four years.
All RFL match officials will sport BLK match day and training apparel, while the RFL’s development and performance staff will also wear specially designed BLK kit.
The new England rugby league jersey will be launched later this year.
Jason Sintome, BLK’s chief marketing officer, says: “As a brand dedicated to assisting athletes and teams to achieve the goals and success they strive and train for, the team at BLK look forward to playing our part and celebrating the achievements as England strive to realise their ambitions.
“With the sport’s new structure ushering in an exciting new era for rugby league in the UK, we are delighted to have the opportunity to play our part in a continued success story.”
