I wear m-frames. Blue sweep in summer, persimmon in autumn, and clear in winter.
Had a variety of crystal frames, and they tend to fracture in the cold. Solid colours are more durable, but still fragile, as the hinges are so small. Just moved to a "modern" M-frame with a beefie hinge, but the lens isn't held so tight and the arms are longer and catch up in your helmet.
