The Julbo Alti Arc 4 mineral glass is a category 4 lens providing unequalled optical quality and excellent protection from high UV conditions with a visible light transmission rate of 7%. While the Alti Arc is highly scratch resistant it is more fragile to high impact collisions than Julbo Reactiv lenses.
With this re-release, Julbo offers much more than a pair of sunglasses: pure emotion, and the alchemy of shiny metal, soft leather and rivets, backed up by high-performance mirror lenses. Comfort and vision in the mountains, with equally good credentials for town or your travels.
