Sizing is a problem.  Large fits good in one style, but not another, X-large is too big in one, good in another.  Makes ya crazy.  About all you can do is best guess and hope the size is right, or order a large and an x-large and return the one that doesn't fit...

I like dorfman's hats, and have a half dozen of them.  The quality is excellent and the variety of styles and colors is great.  The only thing I don't like is the fight of finding the right size.  The price paid for not being able to fit them in person.
