Foam. 10″ wide. Mex Blanket upholstery over vinyl. This traditional blanket originated from horseback, to custom cars & motorcycles. A true rough looking classic. Otherwise the seat is identical to the regular lean & mean Bare Bones solo seats. Note: The Mex Blanket is an actual blanket, in varying colors(!), over vinyl. Designed to give Street Credit, and lots of it! However, they’re not made for longevity since they may unravel, snag or fall apart. No warranty on Mex Blankets. Note: 00-17 Softail seats come in three versions. 00-07 with tires up to 150mm, with frame mounted (FrameM) seats. The 08-17 models, with tires up to 150mm and 06-17 200mm Wide Tire models with fender mounted (FenderM) seats. These are not interchangeable. Note: A matching passenger seat is not available.
