Polarized sunglasses Gamakatsu Racer g-glass Racer gray / Red mirror

6-layer lenses
G-glasses are made of 6 layers:

• 2 hydrophobic layers (1 and 6) intended to evacuate water and snow from the surface of the lens
• 2 layers (2 and 4) with anti-scratch coating
• 1 high quality polarizing layer (3)
• 1 multilayer with anti-reflective coating (5) that absorbs light and prevents it from bouncing the back of the lens into your eye, eliminating bouncing and distracting reflections
