I found this cool GoPro hat mount that I had been using. Thanks joeystoll42! But I didn't always like trying to clip or unclip the camera and just found it easier to take off my hat to make adjustments. So I eventually remixed this with just a simple mount half on it and it works great on all the hats I wear.
