Ray-Ban Tech RB8301 sunglasses are all about innovation and use of new materials. This Ray-Ban Tech segment highlights the use of carbon fiber. Carbon fiber and a resin composite create a lightweight, strong, flexible, and resilient material. The Ray-Ban monel Aviator inspired sunglasses have a smaller rounded eye shape and is paired with slim elongated carbon fiber temples. The Ray-Ban temples feature the metal Ray-Ban signature logo and rubber temple tips for added comfort and non-slip grip on these sunglasses. The RB8301 sunglasses come with polarized lens and an extra set of crystal lenses are included.
