If ya seem to be right between a L and XL, go larger? I want the cap to fit well, but not exactly sure how to measure. Actually it looks like I'm just at 7-1/2, which is at the lower end of XL, but just bought an irish wool cap that's L, and I like the snug fit. One of my fedoras (the only one labeled for size) is XL and fits great.

An art & a science? It's one thing to go to a store and try hats on. For what I want to get, that just doesn't seem possible!

Any suggestions? Thanks!
