Hats?
 

Maybe I'm just getting silly here, but I'm curious if hats are OK-

Naturally not something tight that's going to increase the headache, but I wonder... is even the slighest pressure on the head from a hat not advised?

Thanks-

I survive with a hat to block bright lights. I know to not wear a hat that is too tight. My favorite is a Crocodile Dundee type crushable hat.
