This item was used daily for going to and from daycare and playing in the snow in Aomori City, where winters are harsh, so its cold-weather protection is excellent! It can be used even at ski resorts in mid-winter. The size is 6-12 months (approx. 70cm). It should still fit, but it's now too small for my child. I've washed it several times (the tag says it's washable), but because it's an outdoor brand, the down quality is good and doesn't flatten, and the fleece material inside remains soft, making it extremely comfortable to wear. There is some wear on the cuffs, so please check the images carefully before purchasing. Thank you very much!
