Binky Bro ‘Bonzai’ Wool Blend SnapBack Cap The Bonzai youth snapback hat is grey herringbone, with a triangle leather binky bro patch, with a SnapBack. 45% Wool, 42% Polyester, 10% Viscose, 3% Nylon Used, good condition Size: Youth (3years-6years) Bundle for a discount 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.
