The Halo sunglasses use Category 3 lenses with 100% UV protection to keep your eyes safe and non-squinty from valley floor to mountain top.
The wrap-around style and arm grips stop the Halo from falling off when you're looking down for foot holds or bouncing along the trail. Plus small vents at the bottom of the frame allow airflow through if you start misting up.
Category 3 lenses block out 80% of visible light, making the Halo suitable sunglasses for all but high altitude and glacier trekking.
