Engineered for maximum value, our Heritage Collection is designed with price in mind, so lighter weight components are used. We don’t however lower our standards; all Heritage products are produced to the same ISO policies, and afforded the same care and attention as our heavier duty Classic, Authentic or Vintage Collections.
