Ermenegildo Zegna’s longtime ambassador, Eli Manning, drew a well-heeled group of fans to the Italian luxury brand’s flagship on Fifth Avenue for a fund-raiser earlier this week.

Manning, the New York Giants quarterback, was the marquee host at a fundraiser for the Robin Hood Foundation, an organization he has long supported.

Manning, who looked lean and in peak condition in a midnight blue two-button made-to-measure notch-lapel Zegna suit, said he’s begun working out with the team already to get ready for next season, concentrating mainly on flexibility and strength training.

Manning was also wearing a blue limited-edition Robin Hood tie that Zegna created especially for the evening. It was available in two colors — light and navy blue — and included the Robin Hood Foundation logo. Fifteen percent of the sales from the tie were donated to the charity.

He said he first became familiar with the charity around seven years ago when he attended a breakfast event and heard stories from some of the people Robin Hood had helped.

“It was very emotional for me and it made me jump on board to see if there was a way to help out the many organizations that Robin Hood works with,” he said.

Manning has been a member of the foundation’s Leadership Council for the past couple of years.

“It’s a great charity and they’re doing a lot of work to fight poverty in New York, which is a major problem,” he said.
