My head is average sized but my hair is thick.  This hat is cute and the fabric seems like it'd be very cool.  But it sits on top of my head, and even with the elastic stretched as much as it can it doesn't come down enough not to pop right back off.  So, I like the hat a lot.  My kids will probably wear it, but it's just too small for me.  I can wear other baseball caps with no problem.
