Headwear 100% Polyester Although it says "for baby," this was given to me at a strider race, so I think it will fit 2 and 3 year olds. Detailed sizes are in the photos. It says 45/51 (cm) (^^) Please check the images for various ways to wear it. It also seems like it could be used as a scarf. The pattern is a cat and fish bones, which is very cute! My son didn't want to wear it, so it has been stored at home without being worn (^^) Brand new, unused. #Strider #Skateboard
