Our Snapback hats are true-to-size based on the child's age. What this means is the average sized kid--about 50% on the growth charts--is used as the barometer for head circumference. If you have a child whose age fits evenly between the ranges (4months-12months, 12months-3 years, 3years-6years) or you know is larger than average, it might be best to size up rather than to size down.
Snapback hats are adjustable in the back. The bill and front panels are not.
NOTE: mid-fit and semi-structured hats. (Semi-structured means the front paneling has a half sized piece of visible webbing in it. This webbing will give the base of the front paneling some form.) It will fit slightly more shallow than our standard hat. This hat also has more of a traditional bill shape in all sizes.
