Don’t be fooled by the simple, bold shape of the RB4215: there’s nothing ordinary about them. They are made of LiteForce state-of-the-art thermoplastic material, used in cutting-edge industries such as aeronautics or medical implants. This gives them unmatched lightness and comfort while being extremely resistant to wear and tear. And if that’s not enough, this model also features rubber temple tips for even more comfort and stability. Next-gen tech has never looked – or felt better.
