While I realize these are more appropriate for fall and winter, I just saw a new video that featured someone wearing one, so I had to know more . . .and then share it with you!
I found several sites with information and pictures. If you like the look of them, you can beat the Christmas Rush and order or start creating one now. The links are below the video.
Below is the short video clip showing someone wearing one. Enjoy!
