FITTED HATS

Fitted Caps are closed caps with a fixed size. Fitted Caps are classically available from New Era as 59Fifty, which is the official Onfield Cap of the MLB. Also in the NFL Fitted Caps are worn as 39Thirty or 59Fifty on the sideline by players. You can find out your Fitted Cap size by measuring your head circumference and comparing it with the size chart (which can be found with every cap on the site).
