The Sideline collection features an Oversized Arrowhead Logo in tonal embroidery. New Era® engineered Performance Poly fabric featuring CoolEra™, DryEra™, and ZoneEra™ technology--proactively responding to changes in skin temperatures to keep you cooler when you are hot and warmer when you are cool. The New Era 39Thirty is the classic flex fit hat worn on the sidelines by your favorite Chiefs players. The Kansas City Chiefs Pro Shop is your number one source for official NFL licensed Chiefs gear and apparel.
To figure out your hat size, measure your head with a tape measure about a half-inch above your eyebrows where your hat will rest. If you don't have a tape measure, use a string and measure it against a ruler.
If you are unsure or between sizes, buy the larger size.
