Cincinnati Reds Reversible Wristband Bracelet. This is a lightweight and durable wristband made from polyester elastic. These will easily stretch an additional 3-4 inches so you can easily get them on and off. The wristbands are available in 1/2 inch and 3/4 inches tall. Reversible - one side is black with red letters and the reverse side is gray with red letters. This goes with any Reds gear! Closed with a black ribbon. Size Guide: Best is to use a flexible measuring tape and measure your wrist. This will allow you to have it made as tight or loose as you prefer to wear it. I know sizing for these can be difficult for gifts but the most common sizes that I sell to women is 6.5 and 7 inches. The most common sizes that I sell to men is 7.5 and 8 inches. Hopefully that helps! These are unisex - made for both men and women. The elastic does contain latex.
