Prince Harry went under the radar during his latest outing.

On Dec. 22, Page Six reported that the Duke of Sussex, 41, skipped his princely title while competing in the St. Regis World Snow Polo Championship in Aspen, Colorado, last week.

“Harry was introduced as Harry Wales, with no royal title mentioned ever or anywhere,” a source told Page Six.

“He was there to play polo with his best friend Nacho [Figueras],” they added. “No titles, just fun.”

PEOPLE has contacted a spokesperson for Prince Harry for comment.

King Charles’ younger son made a surprise appearance at the snow polo tournament in Aspen last week. A spokesperson for the Duke of Sussex confirmed to PEOPLE that he was standing in for a friend at the sporting event.

Like his father and brother, Prince William, Prince Harry is an experienced polo player.

Professional polo player Nacho, 48, is a close friend of Harry’s, and the two were spotted skiing together earlier in the day on Dec. 17. The pals didn’t play on the same team, as an Instagram post from Aspen Snow Polo revealed that Prince Harry saddled up for the Aspen Valley team, while Nacho teamed up with his sons, Artemo and Hilario, for the St. Regis squad.

The Duke of Sussex was called “Prince Harry” in Aspen Snow Polo’s Instagram post about the players involved, and it’s a surprise that he was reportedly called Harry Wales.

Wales was the last name that Prince Harry and Prince William used when they were in school and serving in the British Army, with the surname derived from Charles’ former title as the Prince of Wales.

It’s a tradition within the royal family for children to take their parents’ royal titles as the basis for their last names. Today, William’s children are styled as Prince George of Wales, Princess Charlotte of Wales and Prince Louis of Wales, as he now holds the title of the Prince of Wales as heir to the throne.

The late Queen Elizabeth gave Prince Harry and Meghan Markle the royal titles of the Duke and Duchess of Sussex on their 2018 wedding day, and they retained those titles after stepping back from their royal roles in 2020.

Their children’s titles are Prince Archie of Sussex and Princess Lilibet of Sussex, and PEOPLE understands that Harry and Meghan adopted Sussex as Archie and Lilibet’s last name.

Earlier this year, Meghan also explained that her last name is Sussex in an episode of her Netflix series With Love Meghan, when she corrected her friend Mindy Kaling about what to call her.

“It’s so funny, too, that you keep saying Meghan Markle. You know I’m Sussex now,” Meghan said.

Exclusively speaking to PEOPLE in 2025, the Duchess of Sussex, 44, opened up about how much it meant that her family was bonded by their shared last name.

“I love that that is something that Archie, Lili, H and I all have together. It means a lot to me,” she said.

Meghan said the Sussex name “is part of our love story,” and added, “I think as the kids get older, they’re so excited about, ‘Oh my gosh, Mama and Papa, how did you meet?’ I think that will come with time as they get older, but for right now, a huge part of our love story is that we share the name Sussex.”
