This is my third Outdoor Research hat, and I like them all. I have a big head and finding a hat that is rated at XL and really fits well can be difficult. I'd say this hat is 7-5/8" to 7-3/4" give or take, so if you wear a hat in that range, it might fit you.

The hat has a light checkered pattern on it so it is not just boring flat black. It folds up easily and can fit in my pocket when I don't need it. Great to have during wet weather when I don't have a hooded jacket on.
