This is a bucket hat for toddlers (^^) It doesn't have a chin strap, but it can be worn quite deeply, so it seemed like it would be okay in a little bit of wind. (Although, it probably depends on the child (^◇^;)) Size: 48 cm Around 6 months to 1 year old? I'm selling it because my child has outgrown it. I don't see any major stains, but it has been stored at home for a long time, so please refrain from purchasing if you are sensitive to such things. I plan to fold it up small (and compress it) for shipping. I will ship it via Yu-Packet Post Mini, so please be aware of that. Tags: Hat Sun protection Cap
