EDZ layers combine to create a versatile layering system for use over varying temperatures that is not bulky & allows the wearer to choose the best combination for the prevailing conditions. Riding a motorcycle is not much fun if you are not comfortable, if you are too hot or too cold, if you are freezing or your skin is sticking to the linings of your leathers. The EDZ range has been developed specifically for the motorcyclist who may be wearing close fitting outer layers across varying temperatures, conditions and speeds.
