Under Armour has replaced Adidas as the sponsor of Premier League club Southampton FC in a bid to bolster its presence in football.
The Baltimore-based brand will design the Saints home and away kits from next season and will supply the club's youth academy with over 5,000 pairs of football boots.
Through the new seven-year deal Under Armour said it will provide the first team with "revolutionary" products and will also work with the Saints Foundation to kit out more than 5,000 children in the local community.
The sportswear manufacturer has also pledged to develop women's and girls' football as well as support healthy living initiatives through technology and activations.
Peter Murray, vice president of global sports marketing at Under Armour, said: "Southampton FC, like Under Armour, is Humble and Hungry. They are an institution with strong core values based on a pioneering attitude.
"The club's commitment to developing and improving players at every level continues to set a benchmark in the sport. We look forward to providing game-changing technologies and product innovations to further support the club's on pitch performance."
