The Smith Embark ChromaPop Polarized Mirror Cat. 3 (VLT 14%) glacier goggles keep your vision clear in the mountains. They withstand extreme and changing weather conditions, allowing you to focus on skiing or mountaineering without worry. The polarized, contrast- and color-enhancing ChromaPop lenses bring out details like glacier crevasses. The removable, ventilated side shields block peripheral light, while the adjustable temples and Megol nose pads optimize the fit. Additionally, these alpine sunglasses come with a retention strap that keeps them securely in place during fast descents.
