Hats can shrink. Never wash it in tha washer, if ur gonna clean it, do it wit a cloth n soap / cleanin detergent - in COLD water. I didn't pay attention wit a hat n washed it wit pretty hot water (obviously it can cause shrinkage) n it ended up shrinkin. Not shrink majorly, but it's alot tighter than it was before, where was when I was my other hats wit cold water with a wash cloth, they're fine.
Peace!
