This nearly indestructible frame is the only Eye Glass frame in the world that is flexible, yet looks like any fashion acetate style. FlexiTwist is made from an innocative Swiss technology. This memory thermoplastic is the material used in all of our FlexiTwist glasses. FlexiTwists durability is a by-product of its flexibility. A highly flexible frame is less likely to break under stress or impact than a more rigid frame. Its extreme flexibility, durability and light weight make it the perfect material for performance eyewear. Plastic slash acetate and its the only bendy frame in the world available in “Non-Metal” styles.
