Main text in the main banner not responsive in phone view

Hi, I am really enjoying this theme. However, it is with the exception of one issue. In the computer and tablet view all is well. However, in the phone view the main text in the main banner on the home page does not appear to be responsive. It is just one word but it is a long one, with 13 letters. Is there a way to get it to fit properly? Thanks in advance!
