The Arnette Witch Doctor is awesome! Not only does the Witch Doctor come in lots of colors but has lots of features too! The frame is made of a flexible grilamid which makes it extremely lightweight and durable. Natural temperature changes leaves the Witch Doctor unaffected because grilamid allows the frame to maintain it's shape. Harsh conditions do not bother the Witch Doctor. The Witch Doctor is part of the Arnette Creative Exchange System (A.C.E.S.) which means your temples are interchangeable. An extra set of temples are included with every A.C.E.S. frame. Sweet, right?
