Tips:

How do I determine my Hat size?

Measure your head, then use the hat sizing chart below. To measure your head, take a flexible tape measure and wrap it around your head above your ears and eyebrows where your hat would normally sit.

If your head size falls between two sizes, we strongly recommend that you choose the larger of the two sizes.

Window insulation foam works great behind the sweatband to make a large hat fit perfectly.

Head sizes and shapes differ from region to region. The most common male size is 7-⅜ and the average hat size for females is 7-¼.

Please Note:

Size charts are for general reference only. Fit may vary depending on the manufacturer, materials, construction, and hair style.

One-Size-Fits-Most (OSFM) and Adjustable hats typically fit up to XL or 7-⅞, unless otherwise noted.
