My son plays a video game with Russian spy or characters. It's became very inquisitive about Russia and asked for this hat for his birthday. He wears it EVERYWHERE, every day and has gotten quite a few compliments. It must be durable because he hasn't destroyed it yet (been a month). The medium fits an 11 yr old fine. I'm pretty sure the NSA will be stopping by our home home to investigate reports that we have a very short spy living amongst us...but at least he loved his birthday gift.
