There currently isn't any sizing information for this product.
PRO: They have a wire over the nose for less fogging. They are roomy, cover a lot of the face, and balloon out with pleats, so they are not tight to the face. The outside is made from the standard polyester fabric used in competition swim suits, which is a familiar feeling for swimmers. They are inexpensive, running $25 for a pack of five and $100 for a pack of 25, in the most common colors for competition swim suits. They come with your choice of ear loops or ties. CON: They are made from swimsuit fabric, so you have to line dry them. This is a warm day, and I am finding that the good fit around the face makes them warm to wear.
