Winter warmth begins with socks on the feet and a hat on the head, for that's where you'll lose heat fast if either are bare. Teach your youngin' this early on with the Kids' SmartWool Merino 250 Reversible Pattern Cuffed Beanie and you'll be setting them on a path to success. The midweight strength wool will make for whine-free mornings even on the colder days, and the low-profile seams mean this hat can be comfortably worn under their helmet.
