These baby hats are about as comfortable and cozy as you can get. Inspired by the full head coverage and chin strap of vintage aviator style hats, these infant hats are fully lined with super soft fleece to keep your baby's head warm. The outside is our brilliant, multi-colored and multi-patterned knitted cotton, just like our socks. Proudly crafted with care and made in the U.S.A. with recycled cotton yarn.
