Protecting yourself in the sun is very important, not only when you are working in the garden. This lightweight cotton hat has a sun protection factor of 50+. Once you wear it, you'll start taking it everywhere you go. One size with adjustable inner drawstring. 3" brim. This hat is machine washable, but we recommend that you do not put it in the dryer. In order to retain its shape, take a mixing bowl that's about the same size as the brim of your hat. Turn the bowl upside down and fit the hat over the bowl. Let air dry. By doing this, once dry, your hat will still look its best.
