The Arnette Dropout is awesome! Not only does the Dropout 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 Dropout unaffected because grilamid allows the frame to maintain its shape. Harsh conditions do not bother the Dropout. The Dropout 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?
