Roger Federer has switched apparel sponsors, unveiling a new partnership with Uniqlo at Wimbledon.

Federer wore a white outfit as he walked out on Centre Court on Monday to begin his title defense, the Swiss star's first official appearance for a new brand since his contract with Nike recently ended.

The company issued a statement minutes later saying Federer would be a global brand ambassador for the firm and would wear its outfits at all tournaments this year.

According to reports the deal is worth US$300 million (NZ$447m) over 10 years, despite the fact the 36-year-old is nearing the end of his career.


The 20-time Grand Slam winner had been one of Nike's most high-profile ambassadors.

Federer beat Dusan Lajovic of Serbia 6-1, 6-3, 6-4 as he began his quest for a ninth Wimbledon title.
