Most listings specify 100% cotton—often cotton twill or a knit construction—and several also note a 100% cotton lining.
Most use an adjustable back closure—commonly a tuck-and-slide mechanism or a traditional adjustable strap—so the caps fit a range of adult head sizes.
Listings primarily use “One Size Fits Most” or “Adult General Sizing.” One listing also displays a kids sizing label, so sizing is generally presented as one-size or general adult sizing.
Listed brim lengths range from 2.5 to 2.75 inches, and crown heights range from about 4 to 4.25 inches.
Care instructions vary by listing: several recommend hand wash and line or lay-flat drying; one specifies machine wash and tumble dry; another advises hand wash in cold water and lay flat to dry (avoid machine drying).
Most of the hats highlight embroidered designs or embroidered artwork on the front as the primary decorative detail.
Listings describe an unstructured, low-profile construction with breathable fabric and ventilated eyelets, plus a soft inner sweatband lining for added comfort.
