Fishing needs a pair of sunglasses that, on sunny days, protect from annoying glares effects caused by sun rays. Bertoni's fishing polarized lenses eliminate the reflections of the water without attenuating the brightness. Most part of our frames are made in anticrash PC or TR90. TR90 Grilamid® is a special nylon studied for frames used in sport activities. It offers extreme strength although it is light and flexible adapting itself perfectly to the face. It has a "memory" which keeps its shape and elasticity even in extreme temperatures.
