Carbon Blend for Lightweight and StrengthThe Legere Square Sunglasses are a rimless 2-base shield design for an ultralight and comfortable fit. They are made from 100% proprietary blend of carbon and TR90 which offers the strength and lightweight features of carbon combined with the comfort and durability of TR90. The Legere contains B2 spherical shield lenses cut and etched to create the look of 2 separate lenses. These Ultra HD lenses are manufactured in France from shatter proof and impact resistant polycarbonate, and the Hydrophobic and Oleophobic lens treatment repels water, dirt and oil.Weightless-LimitlessDeveloping UltraCarbon technology for the Hypercraft model led to expanding the benefits of its strength and weight savings into 100%'s Active Performance range with two new Legere models. Utilizing the same UltraCarbon technologies and process, the Legere is designed to be the new everyday favourite sunglasses for active and style conscience athletes. The unisex silhouette of the single shield lens is enhanced by the detailed etching around the perimeter, giving it a unique look while being so lightweight it feels as if you’re wearing nothing at all. Feel Nothing. See Everything.
