I bought a pair 10 years ago when the lenses were grey (my preference, but no longer available). I've worn them climbing Mt. Kilimanjaro, hiking the W in Patagonia, crossing the Salkantay Pass in Peru, snowshoeing in Antarctica and last year in Svalbard, near the north pole. They have been incredible! They give clear vision in all kinds of conditions in snow, clouds and bright sun. I cracked a lens last year in a zodiac doing a landing on a beach in Svalbard, and for that reason only, I am buying a new pair.
I absolutely love them and won't hike without them.
