Felted wool is so warm and the earflap hats will also keep your head dry. These hats have a cotton headband lining knit right in. Felting softens the wool and closes the knitted stitches keeping wind and rain out! When the wind is howling or snow blowing, use the ties to snug in warmth. Gentle wash, mild suds, lukewarm water. Lay flat to dry. 21"around. 8" from crown to hem. Ties are 15" long. Browse the full Purple Hummingbird Woolens shop at https://www.etsy.com/shop/HummingbirdWoolens
