Zac Efron & Darin Olien on Down to Earth with Zac Efron (2020)

The final episode of the Netflix series Down to Earth with Zac Efron got Zac out of his shirt once again. He was clad in swimming trunks again for Episode 8, as Zac visited Peru with Darin Olien. They explored the benefits of plant-based Ayahuasca treatments. This required Zac to strip out of his clothes and get wet in preparation for the experience. Darin appeared shirtless briefly during the sequence as well.
