High quality materials, exact fit for the motorcycles it is designed to fit (there are different seats for different models). The seat is anatomically designed for comfort and correct ergonomics. The same seat comes without the conchos and studs, for those desiring a less "western" look. The use of non-leather fabric eliminates or slows the degradation inflicted by weather and exposure to the sun. I've had seats from the OEM to vendors such as Russell, Sargent, Pera, and Corbin, and I prefer Mustang for my Harley.
