The Brim Sun Protection Hat provides all-day sun protection for baby's head, neck and eyes. The wicking liner is breathable for comfort, and the UPF 50+ material dries quickly if it gets wet to support baby's active play. The tie strap keeps it in place, and the adjustable toggle creates a custom-fit as baby grows! Parents love how easy it is to pack for on-the-go activities and the wide variety of classic colors.
