Great cap, well made, stylish. The one size fits all sizing is not comfortable if your hat size is +23 7/8. It will go on, but too tight to be worn for long.
Though the real test for me is how it does over time (does it hold together well?), my first impression is that it is well made, and well styled. I got this as a gift from my wife - I am wearing it a lot!
It's very nice, comfortable, and warm. I have a larger head, and it fits fine. Very pleased!
