Big Brim / Floppy Hats – Big brim and/or floppy hats are exactly what the name implies. They have become more popular and fashionable recently and are great pool hats for women. These brims can get up to 10 inches but more often are between 4 and 6 inches. They come in a variety of colors and are typically made of paper-braids or tweed material because it is slightly stronger and can support the weight of the brim better. Most always the crown style is the simple unformed rounded shape.
