This hat keeps bitter wind from dashing away with baby's heat. It has a skin-pampering interior of polyester high-pile double-faced fleece, and a weather-resistant shell made of all-recycled polyester ripstop with a Deluge® DWR (durable water repellent) finish. Long earflaps provide storm coverage; they fold up and snap out of the way when the sun starts shining. The paneled construction creates a sure fit.
