Ahh, these bring back memories of my dad in the summer when I was a kid. He always wore them and now I know why - they are super convenient. Maybe not the most stylish - maybe not stylish at all but very functional. The real downside is that they are easy to lose. I am embarrassed to say how many I go through in a year. The clip-ons beat the hook on kind without a question. Just don't EVER put them in the flip up position, only our dads could get away with that.
