The son of everyone’s favorite Crocodile Hunter is all grown up.

Robert Irwin, the son of late Steve Irwin left little to the imagination in a new ad campaign for Bonds, an Australian underwear brand breaking into the United States market with a friendly face. Bonds teased the release in the U.S., but hasn’t released photos of the conversationist just yet.

“You guessed it! BONDS IS LAUNCHING IN THE USA! Stick around for a BIG ANNOUNCEMENT tomorrow. Make sure to turn on your post notifications.8AM AEDT | 5PM EDT | PDT 2PM,” the company announced in a post on social media.

The 21-year-old admitted it didn’t take much convincing to make him the face of the new campaign in the States.

“It was a pretty immediate yes,” he told People. “I wish I could say I was very suave and cool about the whole thing, but I was like, ‘Yes! Let’s do it!’ Because Bonds in Australia is an absolute icon.

“Also, I’m at this point in my life where I’m trying to do as many different and random exciting things, and if it’s something that makes me a little bit nervous, that I’ve never done before and it’s a bit of an adrenaline rush? That’s what I want to be doing.”

Irwin revealed how he stays so fit – and why he opted for a little extra training before the shoot.

“I’ve got to stay pretty fit with all the crazy stuff I’m doing,” he said. ‘I’m saving crocodiles, I’m in and out of the Aussie bush every day and it’s hard work, so you’ve got to keep pretty good upper body strength, good stamina.”

“I’m representing Australia!” he added. “So I wanted to look my best and to feel my best and just feel really confident. And so I’ve done more sit-ups and had less carbs than I ever have in my life, but it’s been fun.”

Photos of Irwin’s campaign can be found on People until their release on Bonds’ social media platforms.
