This bucket hat goes on when the sun rises above the horizon and stays on when raindrops start to fall. Its made of a durable 100% 3-ply Supplex nylon with a DWR (durable water repellent) finish and 50+ UPF sun protection. It reverses to either a solid color or a fun print. The generous brim on this baby sun hat shields the head, face and neck, and a tuck-away chin strap with hook-and-loop fastener holds securely without chafing tender jawlines. Buttonholes in hat allow chin straps to thread onto reverse side. Packs small; easy care.
