Figueras began playing polo at the age of 9. He turned pro at 17, playing at various locations in Europe before arriving in Bridgehampton, New York in 1999. There, he joined White Birch, a team shared at the time by Peter Brant and Neil Hirsch. He currently plays for and is captain of BlackWatch, a team he co-owns with Hirsch.
When he was approached by the photographer Bruce Weber 12 years ago, at a dinner party held by Kelly Klein, ex-wife of Calvin, in The Hamptons, he hoped modelling might help him buy more squirrelly mounts. "Then I realised that I could make extra money, and raise awareness of the sport." Nacho started modelling for Ralph Lauren in 2000, eventually become the face of Ralph Lauren Black Label in 2005, and has been under contract since. In May 2009, he was made the face of the World of Polo fragrances, including Polo Black, Polo Blue and Polo Modern Reserve. Black Watch is also a label under the Ralph Lauren umbrella, offering tight polo shirts emblazoned with Nacho's number 2, an idea of Figueras' to make it a billion-dollar brand.
In June 2009, he was voted the second most handsome man in the world by the readers of Vanity Fair with 15% of the vote, far behind Robert Pattinson, who drew 51%, and ahead of Brad Pitt, who drew 12%.
Despite his success in the modeling arena, polo continues to be his passion. He says his mission in life "is to bring polo to the world a little more," doing his best to raise the profile to the sport of polo however he can. To that end, he has helped organize matches such as the Veuve Clicquot Manhattan Polo Classic exhibition in Governor's Island, New York; the most recent edition on June 27, 2010 also featured England's Prince Harry.
In October 2010, Nacho Figueras co-hosted the Veuve Clicquot Polo Classic with Cameron Silver in Los Angeles at Will Rogers state park attracting celebrities and socialites like Minnie Driver, Mischa Barton, Donovan Leitch and Rachel Zoe.
He appeared as himself in the 44th episode of the CW television series, Gossip Girl , third season premiere "Reversals of fortune", aired in 2009.
On September 28, 2009, Figueras was a guest on The Oprah Winfrey Show in Chicago. The show was titled "Meet the Most Famous People in the World", and also featured the "Oprah of China" Chen Luyu, and Aishwarya Rai and Abhishek Bachchan. In one of the segments on the show, Nacho gave Oprah's reporter Ali Wentworth a private polo lesson.
Nacho was born in 25 de Mayo, Buenos Aires Province. He has been married to Delfina Blaquier, a photographer and former model, since 2004. The couple currently have 4 children, Hilario (Laio), Aurora, Artemio and baby Alba born January 19, 2013.
