Are New Era 59FIFTY hats worth it?
The New Era 59FIFTY is the official on-field cap of Major League Baseball and the gold standard of fitted hats. At $40 to $55, you get premium wool/polyester construction, authentic embroidered team logos, and a fit that breaks in perfectly over time.
What is the difference between a fitted hat and a snapback?
A fitted hat (like the New Era 59FIFTY) comes in specific sizes and has no adjustable strap, so it fits snugly to your head measurement. A snapback (like the 9FIFTY) has an adjustable snap closure and is one-size-fits-most. Fitted hats offer a more precise, premium fit.
