Your Vuarnet Polarized Glacier XL Sunglasses put up a solid line of defense against harsh mountain sun while you're crossing sparkling glaciers in the alpine. These polarized shades work to reduce the flare from the sun, with removable leather blinders that protect your eyes for long days in the mountains. The leather cord fastening system holds your shades securely in place, but can be removed if you're ready to transition to a more urban lifestyle.
