This train engineer hat is for children. The hat is adjustable on the back, like the baseball caps with the little plastic knobs on one band and holes on the other band. Fits most children and even some adults!

Size information: At 1 or 2 holes below the largest adjustment setting (which is probably the largest you would want for the best look), the inside diameter is 8.5 inches. If we measure it like the other hats we sell, measurement around the child's head should be 22 inches or less. You can adjust down from there if needed. Keep in mind that the depth of the hats, as well as the brims, are actually sized for children, but these will also fit most teens and even some adults. They look better and fit better on younger children.

Please note: This listing is for the hat(s) only. Also see our train whistles, train conductor scarves and our 3-piece train engineer sets! We also carry the deluxe quality hats.
