High performance sunglasses for high altitude trekking and mountain use. Reactive lenses rapidly adjust to match light conditions, from overcast flat light (category 2) to the highest level of protection for exceptionally bright sun+snow conditions (category 4), meaning just one pair of glasses can provide a full spectrum of protection in the mountains. Polarisation gives additional protection from glare for even more eye comfort.
