Find your perfect fit in 2 simple steps
Measure the circumference of your head
To determine your Notch stretch-fitted hat size, measure the circumference of your head where the sweatband of your hat will sit; just above your ears and across the front of your forehead approximately 1 inch above your eyebrows.
If you don't have a sewing tape measure, use a piece of string and measure it against a ruler or metal tape measure. Find your measurement on the size chart to determine your hat size.
Please note: If you’re not sure which size to order between two sizes, go with the smaller size. Keep in mind, stretch-fitted hats may vary slightly within the same size category; one S/M may fit slightly differently than another S/M of the same style.

Decide which Notch location you need
We offer our patented notches in two locations; Standard Notch and Terra Notch™ (named after our Co-founder).
WRAP AROUND STYLES
The Standard Notch is designed to work with most wrap-around or sport style sunglasses, shooting glasses, and safety glasses. These styles have a curved appearance, designed to conform to the contour of the head.
AVIATOR, WAYFARER & PRESCRIPTION STYLES
The Terra Notch™ is designed to work with most aviator or fashion style sunglasses as well as prescription eyewear. These styles are more squared off at the corners, causing the frame to sit further away from the face.
