We renovate 15X quality and above. You will need to take the hat to our nearest dealer and have them call us for a renovate number. We need the information from the tag inside your hat that tells us the name of the hat, quality, and color. The retailer will need to give you the cost of the renovation. The renovation includes cleaning, blocking, and replacing the sweatband and the liner. There are some stains we cannot remove and we cannot patch holes. If your hat is less than 15X quality you will need to contact an individual renovator.
