A lightweight, classic mountaineering glass at a great price. The Julbo Sherpa Sunglasses offers full bright light protection, reducing visible light by 88% with Julbo's Spectron X3 lens. Moldable temples, removable side shields, and polycarbonate lens all come included. Huge value at under fifty bucks! (Good lookin' shades, too.) Excellent choice for skiers, snowboarders and mountaineers alike.
