The New Era 9TWENTY is a relaxed fit adjustable hat style. This is an unstructured, low profile adjustable hat. This hat comes only in one size, One Size Fits Most, and can have a variety of different closure types (snapback, strapback, velcro back). Sometimes called the dad hat, the styling of the 9TWENTY is a bit of an homage to old baseball cap styles worn in the early and mid 20th century and is often used for throwback designs for a vintage looking style. You can roll this cap up and fit it in your pocket, or easily pack it in a suit case without concern that it will lose its shape. Usually (but not always) this cap is made with a washed cotton. So if you want a worn-in looking cap with a soft, comfortable feel that you can take everywhere, this one is perfect for you.

The 9TWENTY adjustable hat is not the best fit for larger head sizes, as it can look out of proportion and too small on a large head. If you wear a size 7 5/8, you are borderline in having a good fit in the 9TWENTY. If you wear a size 7 3/4 or bigger, the 9TWENTY will look too small on your head.
