1. Measure Your Head

Wrap a soft measuring tape around your head where the hat naturally sits — across the middle of your forehead and around the widest part of the back of your head. Keep the tape snug, but not tight.

2. Adjust the Back Closure

Use the adjustable metal buckle closure to tighten or loosen the hat until it feels secure and comfortable.

Fit tip: This is a relaxed, low-profile dad hat with an adjustable adult fit. It is not a fitted cap and it is not a structured snapback.
