Chris F.wrote a review of Outdoor Research Ghost Rain Hat - Men's on April 27, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
I often spend time hiking, or just being outdoors, in the summer sun. I've had a nice wide brim hat for that. However, when the summer sun is followed by that summer thunderstorm, my rain suit didn't keep my head dry, unless I tried to wear the hood and the wide brim hat together. Not a good look. I am hoping that this hat will do both jobs. It fits well, and it looks good. Storing the rain cover is easy. The descriptions don't say that there is a velcro adjustable headband. I measure exactly halfway between M and L. I ordered a Large and it fits well, snug even with the cover stowed. I'd say this runs small, and with the sizing adjustment, you should probably order a size up, maybe.
