The New Era 9THIRTY cap features 21-wale corduroy fabric, known for its soft, smooth texture and fine ridges. It features an original logo design with an outdoor motif. "21-wale" refers to the presence of 21 ridges within a 1-inch width. The top button has been changed from the conventional metal type to plastic to prevent lightning strikes. MICROERA, which has antibacterial effects, is used for the sweatband. The silhouette is the 9THIRTY, characterized by its soft fit. The rear easy-snap (size adjustment strap) allows for size adjustment from approximately 56.8cm to 60.6cm. Please understand that this is a used item before purchasing. Thank you.
