Last month, Dylan told Bro Bible he had planned a trip Down Under to help produce the second season of Zac’s Netflix series.

‘I’m going to be in Australia for the next couple of months. As soon as I get back, I’m ready to start doing Flow State season two,’ he said, as he referred to his YouTube show.’

Last season, Zac and Darin visited Iceland, France and Costa Rica – but this series will be undoubtedly different due to COVID-19 restrictions.
