Echoing the PivLock? Ruckus, we built the PivLock? Reverb with unisex fit and size. With re-engineered PivLock? interchangeable lens technology, this medium coverage shield comes in at 27 grams and is the lightest-weight shield in our Velocity sunglass collection. The PivLock? Reverb comes with 2 interchangeable ChromaPop? lenses, two-position megol nose pads and thin megol temples for helmet compatibility and no-slip comfort for all day performance out on the bike.
