I don't understand where these jokers get ideas. The use of leather is a by product of the meat industry and is quite green, otherwise we would just be dumping this leather in landfill. At Aero Leathers we use front quarter horse hide, these horses all die from natural causes so it is a very green product, the jackets are designed to last at least your lifetime and hopefully longer, they can be repaired at the factory and horse hide is waterproof. Compare this to the man made fibers that they wear these are all a by product of the oil industry which is by far one of the most unenvirormental industries in the world, where is the argument now.
