Your Go To Guide To New Era Caps

USA Sports stocks five different types of New Era caps – 9Forty, 9Fifty, 59Fifty, 39Thirty and 9Twenty. This product Guide has been designed to help you understand the differences between each and find the perfect hat for you.


59Fifty caps have a fully structured crown, as well as a flat visor at the front. These caps are fitted to the diameter of your head, and for a perfect fit, it is recommended that you measure your head before choosing a size. We currently stock sizes from 67/8 to 8. We also have a size guide below which further explains sizing:

9Twenty caps are an unstructured, low profile adjustable hat. This hat comes only in one size, “One Size Fits Most”, and can be adjusted with the adjustable strap.


The 9Forty shares the curved visor of the 39THIRTY and the adjustable back of the 9FIFTY. The 9FORTY offers an adjustable strap at the back of the hat with a buckle or a plastic snapback, like the 9Fifty.
