The Julbo Micropore Alti Arc X8 Sunglasses offer some of the best visible light reduction found in any pair of glacier glasses. For over 130 years, Julbo has outfitted mountaineers with the best glasses in the world.

Alti-Arc X8 bi-grandient lenses are made from hardened mineral glass that offer superior optical clarity and scratch resistance. When you are moving fast and pumping out a lot of perspiration the Air Flow system works like no other. Air Flow nose bridge draws in cold dry air through perforations in the nose bridge and pushes out warm moist air through the side shields. This reduces lens fogging.

Ideal for mountaineering and other high altitude snow sports.  Vented leather side shields block light above and below the eyes, as well as to the sides, for optimum coverage; can be removed as needed.  

Non-slip temples can be molded for a snug, comfortable fit. Includes a protective hard case and retainer strap for securing glasses around your neck.
