I returned this.  On sizing my head according to an online chart, I am a solid medium. This seems like an extra large that you can cinch up to your size, only I had to cinch it up significantly to have it fit my head.  What happens when the cheap little cincher breaks?  Not to mention that it is simply cheap looking.  The idea of one size fits all in hats is stupid.  I'm not buying a hat on line any more, will look for something that actually fits in a store.
