The Embark glacier glasses are created for eye protection in alpine environments while backcountry skiing and mountaineering.  Although designed with a traditionally inspired silhouette, each detail is modernized for glacier travel and high elevation summits, where snow blindness can have serious consequences.  Removable ventilated shields add side coverage, and adjustable temple arms let you customize the fit.  A goggle-inspired retainer keeps them securely in place during technical moves on the mountain.
