- OPTIMUM CLEAR LENS: 80% Visual Light Transmission (VLT) and designed with complete protection from harmful UV rays, Everclear Anti-Fog, Permashield Hardcoat, and optimal color filtration for enhanced clarity, color, and definition. Provides the highest level of light transmission in our goggle line, allowing for safe skiing, snowboarding or snowmobiling in the worst visibility, or at night.
- RAIL LOCK SYSTEM (RLs): Changing goggle lenses has never been easier with a rimless frame design for unsurpassed peripheral vision and a dual sliding rail system that guides, slides, and locks your lens in place anywhere on the mountain.
- SPHERICAL POLYCARBONATE LENS: Spherical shaped lens that curves both vertically and horizontally to enhance peripheral vison; increased volume creates less distortion and helps reduce glare and fogging.
- ANTI-FOG TECHNOLOGY: Zeal's Everclear Anti-Fog molecules are permanently infused into the lens material and can't be wiped off so goggles last longer against the elements and your vision is never compromised. Advanced venting design allows increased airflow and dual-lens provide temperature barriers between the inner and outer lens to prevent condensation.
