Lighting conditions can change over the course of an extended brick or long-distance race, but the topless Aerospeed with a Reactiv Photochromic lens handles dynamic lighting well. The lens gets darker or lighter, depending on how bright the sun is shining. For those who don’t need the transition, other interchangeable lenses are available for the Aerospeed, including Julbo’s polycarbonate mirror-finish Spectron 3.
