I bought one of these a year ago on a whim and Wow! This hat fit perfect right out of the box, it's a cool hat (meaning a lot of air passes through it). So, it got a little sweaty and I washed it in my dishwasher as I do a lot of my hats that are washable. It came out like the day it came out of the box. I decided to order another (same color, same hat) just to keep in the box, so when my current one finally wears out, I'll have a new one ready to go! I've never done this before. Great hat! Well made!
