Forget collecting a slew of different lenses when you're rocking the photochromatic adaptability of the Revo Moog Goggle. A one goggle solution to skiing through widely variable alpine conditions, the Moog Google features Revo's Polarized Photochromatic Serilium Lens that rapidly adapts to changing conditions in as little as 40 seconds. Saving your eyes from harmful solar radiation, this lens also blocks incoming UV and High Energy Visible light when you're skiing or riding at high altitudes. The polarized photochromatic lens adjusts from 32% to 12% visible light transmission VLT when storm clouds depart and leave blinding sunshine to contend with. The lens tint also changes in the opposite direction, lessening its tint to accommodate quick moving fronts and socked in storms. Additionally, the goggle's 50% polarization cuts distracting glare without sacrificing your ability to read nuances in terrain and view smartphone screens. Designed with a dual lens construction and Air Vent technology, the Moog keeps fogging and built up condensation at bay when you're ripping high speed laps on warm spring days and battling soaking wet storms. The adjustable strap features anti slip silicone beads that ensure a secure fit from first chair until last. Moreover, Revo provides triple layer face foam for an ultra soft feel without irritation.
