Offering a seamless fit with your Marker helmet, the Polarized Projecter Goggles provide the same level of safety you've come to expect from Marker bindings, but for your eyes. The frameless design allows you to switch between the polarized lens and the included extra clarity mirror lens quickly and easily on the chairlift or while you're waiting in the lift line. The full spherical lens matches the curvature of your eyes, providing an un distorted field of vision. Each lens features an NMT coating, which is designed to keep the lens clear from moisture, dust, grease, and scratches. The MarkAir system is designed to keep the lenses ventilated to avoid fogging, while the Superfit frame features an Elastogram plastic that shapes to the curvature of the wearer's face for comfortable fit.
