Yannick Agnel’s sponsorship deal with the swim brand will extend past the 2016 Olympics in Rio.
Known as ‘Squale’ (shark) in his home country of France, Agnel is the current Olympic and world 200m freestyle champion.
“Yannick embodies the values we hold dear at Arena,” Nicolas Préault, general manager of Arena France, says.
“We share his pleasure in performing in the water, his quest for excellence and the ultimate performance, his competitive spirit and determination to win.
“Like the other members of the Arena Elite Team, Yannick will be integral to the research and communication related to the technological products designed for swimming.”
