Zac’s little brother Dylan was born on Feb. 6, 1992, and the two have been inseparable since. The brothers both frequently post about hanging out with each other on social media, includinggoing boating and playing golf together.

In a 2021 interview withBroBible, Dylan said that he and Zac “were always fighting with each other” when they were kids, and he described them as “so different.”

“[T]hen once I graduated college, Zac really took me under his wing and let me live with him when I got my first job in Los Angeles,” Dylan said. “He really became that older brother, and that’s when I would say we grew closer than ever. Our relationship was something that developed more as we both became adults and stopped fighting so much.”

Now, Dylan is aYouTuberand social media influencer focusing on travel and outdoor adventures. On Instagram, he has over 850,000 followers.

“From a young age, my passions have always been fitness and being outside,” Dylan told BroBible. “Not necessarily working out, but just exhausting yourself in whatever it is. That’s what we did for fun growing up. We didn’t have Six Flags or any big concerts to go to in my hometown, it was all about using what was available to us, which was the ocean or the mountains.”

Before making a career of being in front of the camera himself, Dylan worked as a producer, including on Zac’s docuseriesDown to Earth with Zac Efron, which ran for two seasons beginning in 2020. He also popped up on a few episodes ofDown to Earthalongside his older brother, and was an associate producer for the 2020 documentaryBy Hand.

That wasn’t the only time Zac and Dylan filmed a project together. In 2019, they posted aYouTube video seriescalled “Off the Grid” that showed them skiing and spending time in the desert, among other adventures.

Now, Dylan is continuing his career in front of the camera as he was announced as part ofThe Traitorsseason 3 cast. Ahead of the season’s release, which is now streaming on Peacock, Zac had “a good feeling” that Dylan would come out on top.

“He isjust the best at games,” Zac toldEntertainment Tonightin June 2024. “Growing up, he was a first roll [at Yahtzee] kind of dude. If I was him, I would move to Vegas and just play games. He’s that good, so I got high hopes for him.”

Though he may have a burgeoning career of his own, Dylan still prioritizes family — and has been open about how his big brother has inspired him.

“I know exactly the type of big brother I want to be for Olivia and Henry because you were that brother to me,” he wrote in a sweetInstagramtribute for Zac’s birthday in October 2023.
