For: Freebirds™*

A dual-layered spherical lens developed together with industry-leaders ZEISS and fitted with an inner anti-fog lens from Mazzucchelli. 

ZEISS Silver (15% VLT)

An optimal lens for sunny and variable conditions. The anti-reflective mirror coating reduces eyestrain while the brown tint is contrast-enhancing and also puts you in a nice frame of mind for a day on the mountain. 

*The lens does not fit with Freebirds™ 20/21.
