The innovative 553 ZERONOISE is equipped with patented temples specially designed to facilitate the combined use with hearing protection devices: the shorter terminals and the reduced sections cancel the interference with cushions avoiding the ear muff to lose part of its attenuation capacity. The flexible and shaped temples give the operator comfort and allow to wear the glasses without having to remove the ear muffs.
Available in clear and G15 - a solar lens designed with combination of green and gray that is very relaxing and has perfect colour recognition.
