Can you have your purse/ fanny pack on you? If not, can you have your phone on you while zip lining?

You wouldn't want to have your valuables with you. They will store them for you.

They will store any personal items you don't want to take with you and give them back at the end. Don't take anything you can't afford to lose because if you drop it, it's gone.

You can have your phone or a fanny pack. They're just not responsible for you dropping your personal items.
