Like the hat solid materials. Issue with one size fits all doesn't fit big heads like mine. Being used to that I knew it was a risk and just decided to finally invest in a hat stretcher, $16 off amazon. That worked great and now it fits fine. But beware if you have a slightly big head and don't like a tight fit be prepared to stretch it.

Hat was well made and large enough for a size 9-1/2 (which I was worried about). Shipping was quick as well.
