SR OTG SKI MASK + SONAR LENS BLACK - TECH S2-S4

The mask is sold with a ZEISS SONAR replacement lens, patented specifically for skiing, with the particular feature of filtering blue light, thus allowing the eye to identify irregularities in the terrain, which otherwise would not be immediately recognized, and thus to ski in maximum safety. It is a lens that adapts perfectly to all weather conditions with a protection category S2. Tech Lens: New generation lens: the technical characteristics of a lens that is both photochromic and polarized are joined by the silver flash mirroring on an amber base, which increases contrast and gives a more aggressive tone. The category change is from S2 to S4.
