Almost everyone wears a baseball cap these days – they’re a fashion statement as well as a practical sunshade or a cover for bad hair. However, have you ever worried about what would happen if a strong wind blew that hat off? What the hat tether offers is a solution to that problem. The hat tether was patented in the United States in 1997. It has clips that connect a nylon cord from the back of the hat to your shirt collar. Of course, if you want to use this invention, you can’t care about how silly you’ll look with a cap hanging down your back!
