The higher you climb, the more dangerous ultraviolet rays become, and that applies with or without snow on the ground above the treeline. Built for climbers but ideal for anyone traveling through snow and ice, even in the city streets, these glacier sunglasses not only provide polarized lenses with UV protection but also have removable magnetic perforated side panels to further reduce glare and UV damage from your peripheral vision. The lenses have now also been upgraded to a lighter, more scratch resistance Helio polycarbonate lens for an even more premium experience. The glasses are flexible and lightweight, so you barely notice they're on, while rubber nose pads ensure they won't slip off during your next mountain climb or ski run. Each pair is backed for life by Sunski, even if used at 10,000 feet or just on Park Avenue.
