<human>: Which type of hat should I get for my son?
<bot>: The best type of hat to buy for your son depends on his age, size and activity level. If he is a toddler or young child, you may want to look for a knit cap with an adjustable drawstring that will keep the fit snug and comfortable. For older children who are more active, a baseball cap can provide protection from the sun and help them stay cool in hot weather. A fedora might also be a good option if they like hats with brims.
