Ideal for rides that move between shaded and brighter conditions. Lenses adapt quickly. Lots of my rides are on heavily wooded hills where traditional dark lenses are too dark for the shady sections. Pricey withhigh quality optics.
Bought these for the photochromic lense as 80% of my riding is early(ish) mornings when the shadows along tree lined roads make it difficult to differentiate what's what. They do the job! Surprisingly, really liked the slightly taller profile. Allows for better coverage when in aggressive position without have to crane the neck so much.
