Please comment before purchasing to check stock. A perfect bucket hat for winter is here! It protects your ears well and is very warm thanks to the brushed lining! It didn't come off at all, even when dolphin diving or getting tumbled by waves! Also recommended for those who don't like head caps! Sizes: S size: Head circumference 52-54cm M size: Head circumference 55-59cm These are approximate measurements. S size is recommended for women!
