Perception and performance To be content on the mountain, you have to feel comfortable in all of your gear, see everything around you clearly, and have a great attitude. Good style helps, too. Luckily, the Millie goggle can help. With a premium VIVID Lens with Optics by ZEISS, vision is bolstered to enhance contrast and boost confidence. The Millie goggle also feature Seamless Compatibility (so you know they'll fit perfectly with your Giro helmet), Triple-Layer Face Foam with microfleece for a plushy feel against your face, and anti-fog coating to reduce fogging. This winter opt for the Millie, a goggle you can rely on.
