The Active Zenith sunglasses have a wide rectangular frame with removable side shields that block sun and wind at the edges. A slim, bio-based frame with a Soft Touch finish, a peach-skin texture, keeps these polarized sunglasses light on long hikes. What Our Gearhead® Experts Are Saying:“Polarized lenses cut the glare off lake surfaces and wet granite, so I can read the footing on the trail without squinting. My eyes still feel fresh by late afternoon after a long day outside.”
