This Gamer scrub hat is made with quality cotton fabric, is one size & has fabric ties in the back. Approximate measurements: 22.5" in circumference, 7" crown, & sides are 4" in height. I use a zigzag stitch on the inside seams to prevent fraying. A stock photo is used, so pattern placement can vary with each hat. I recommend hand or delicate wash in cold & line dry.
