Distinctively modern. Technologically advanced. Sure they look great, but Bolle Silium Safety glasses are all business. Pure, natural curves make the one-piece metal frame sleek, attractive, and remarkably strong. It offers advantages over plastic frames: more durability, an ideal weight, plus adjustable soft PVC nosepieces and flex temples with Bolle’s TipGrip system for a better fit and maximum comfort. The polycarbonate anti-scratch, anti-fog, one-piece lens features integrated side projections for full protection and panoramic vision. Whether you choose clear or grey, eye protection never looked so good…from either side of the lens.
