What Our Gearhead(R) Experts Are Saying:"I grab these for high-output days when I want maximum field of view and minimal weight. The rimless design feels barely there, and the ChromaPop lens really sharpens terrain details on the trail or road. I like being able to swap lenses depending on light conditions, and they stay locked in place thanks to the grippy nose and temple pads."We reach for the Defy ChromaPop Sunglasses when speed, clarity, and freedom of movement matter most. Smith designed this rimless shield for everything from fast trail runs to long rides, giving us an unobstructed view that keeps us focused on what's ahead. The lightweight feel disappears on our face, so we stay dialed in whether we're climbing, descending, or cruising. ChromaPop(TM) lenses enhance contrast and natural color, helping terrain features stand out in changing light. The interchangeable lens system lets us adapt to shifting conditions, while the cylindrical shield design offers wide coverage without excess bulk. Megol contact points and adjustable nose pads keep the fit secure, and the flexible TR90 frame with AutoLock hinges makes them easy to handle on the move.
