the hat fits our 2 year old son but i will note that the other reviews are correct in that the shade of blue is much lighter than pictured.  as such, it doesn't exactly match the shade of blue of conductor overalls and the light blue color makes it look like a hat that has been well used and loved.

overall, it's okay. the color is not enough of an issue to return but if i wouldn't have bought it had i known what the actual hat looks like.
