Ray Ban's recently introduced ' Tech' collection is all about making their classic models just that little bit more effective. Ray Ban sunglasses are pretty unrivalled anyway but with the addition of subtle technological advances, unbelievably they've been made even more functional. This classic model is enhanced by the use of Carbon Fibre, a material that makes little difference to the aesthetic but instead dramatically enhances their lightweight properties. This makes them light & portable whilst still retaining a sense of durability. As usual they come packaged in a branded leather case & are finished with the iconic logo to the arm.
