The Julbo Sherpa is the choice of budget minded explorers who know you needn't break the bank to find an awesome pair of glacier glasses. Let's face it, expedition costs are not cheap. Add multiple air fares on top of mountains of expensive gear and food and there's not much left over for incidentals. The Sherpa 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.
