One goggle, all day
Freeride days bring changing light: bright ridgelines in the morning, flat light in the trees after lunch. Aspen, Denali, Etna, Eira, Parbat, Everest, Kilimanjaro and Fitzroy come with photochromic options that adjust with it. Arlberg offers smoke or revo gold, blue and red lenses for brighter days.
All share a dual anti-fog lens and a helmet-compatible frame. Most use a spherical lens; Everest, Kilimanjaro and Fitzroy use a cylindrical one, and frameless Fitzroy has the widest view in the range.
