We have to wear the campaign type covers during the summer. My head is kind of long (front to back) and narrow (side to side), so it doesn't fit too well in the nearly round hole in the hat. I ended up having to get a pretty big size to fit the length. I think I actually need a larger size this year, as I'm finding with the hotter temperatures it get's a bit too tight. I'm trying to find a solution to get the thing to conform to my head shape. It would be one thing if I wore it every day, but I only wear it maybe twice a week on details. Any thoughts?
