The tag says 50-54, but it's on the smaller side. I don't think a 54cm head would fit. I think it might fit a head around 51cm, but this isn't certain. The surface is a little fuzzy, but it hasn't been worn for more than one season. The entire hat, including the pom-pom, will be compressed for shipping. Navy knit hat with a pom-pom and earflaps, a warm design. - Color: Navy - Material: Acrylic, Polyester - Design: With pom-pom, with earflaps Thank you for looking.
