This is a kid's knit hat I bought last year. I used it for one season. It was very useful because it kept my ears warm (*^^*) The size is 52-54 cm. Because it's knit, there is some wear and tear like pilling, but I think it can still be used. How about it for after swimming, theme parks, or outings this winter (*^^*)? I plan to ship it via Yu-Packet Post, so please note that the pom-pom will be flattened for packaging. Knit hat For kids Earflap knit hat Navy
