Be prepared to steam and reshape it. It will probably fit right out of the box if you have a very round head, but not otherwise. I had to do some serious stretching lengthwise so that it would not pinch my forehead and bulge out on the sides. Once I did that, it fit very well.
It is solid and well made, with nice heavy felt, an attractive ribbon hatband, and a leather inside band. It is a real hat, much better than the costume tophats I used to get from another source. You could probably wear it in the snow and and have it hold up quite well.
