I bought a small/medium size but it didn't fit my 3.5 year old. Sure he has a big head, but it's a youth size, not a toddler/preschool cap size, so I figured it might fit him. Unlike ordinary baseball caps, it had no stretch or the ability to adjust for fit. He was quite disappointed as he liked the look when I tried it on.
