Piper glasses are made from cellulose acetate, a noble material derived from the special processing of plant fibers, to which plasticizing materials are added to provide flexibility and toughness. The result is a lightweight yet extremely durable pair of glasses characterized by a brilliant and deep color rendering; moreover, thanks to the flex temples equipped with a spring mechanism, they are comfortable and lightweight, adapting perfectly to any type of face. The polycarbonate lenses guarantee 100% UV protection and maximum impact resistance. ---- Model: Smooder Piper Gender: Unisex Frame: Cellulose acetate Lenses: Polycarbonate Type: UV400 Protection Smooder Packaging
