What Our Gearhead® Experts Are Saying: "These are my favorite sunglasses for changing conditions. The Auto Sun lenses adapt so quickly, and the Z-Lite frame is insanely light—I forget I’m wearing them. Great clarity and perfect for all-day use on the move." From mountain peaks to midday trail runs, we need sunglasses that move with us and keep up with every shift in the sky. Enter the Zeal Manitou Sunglasses—ultralight, adaptive, and built for adventure. As the first frame in Zeal’s collection to combine the slim Z-Lite injection frame with Auto Sun photochromic lenses, the Manitou is designed to do it all. Auto Sun lenses darken and lighten automatically with changing light, offering continuous clarity and comfort without swapping shades or lenses. Add in Ellume Polarized tech for enhanced contrast, a plant-based Z-Resin frame, and Proflex grip, and we’re ready for everything from technical ascents to sunny descents—no matter the conditions.
