Zac Efron, Darin Olien & Dylan Efron on Down to Earth with Zac Efron (2022)

The Netflix series Down to Earth with Zac Efron once again got Zac Efron out of his shirt. Episode 5 of the second season featured Zac and his friend, wellness expert Darin Olien exploring self-sustaining habitats and businesses innovating ways to reduce waste and limit their carbon footprint in Australia. The guys also took some time to go swimming with dolphins. This led to shirtless screentime for both Zac & Darin. Zac's brother Dylan Efron, who is a producer on the travel series, was shown shirtless briefly as he joined them in the water.
