Size Guide - Nike Hats and Caps
HOW TO MEASURE
Measure the circumference of your head using a measuring tape. Wrap it around your head at the point where the hat will sit (about an inch above your eyebrows).
FIND YOUR SIZE
Use the chart below to determine your size. If you're on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.
