Custom Denim Seat Covers are the best value and most durable seat covers available. Some people refer to them as Canvas Seat Covers, some call them Denim. Either way our seat covers are made of first quality heavyweight cotton denim material. Our Denim seat covers are fully covered using the same fabric on the front and on the back of the covers, not like other companies which sell one size fit and stretch material in the back not fabric. All Canvas seat covers are made based on the seat pieces.
