Product InformationThe Propel glasses, introducing the concept of aerodynamic gains in sunglasses, are the result of CFD testing and modeling, providing enhanced efficiency in the air. - Propel sunglasses, developed through CFD (computational fluid dynamics) testing, introduce the concept of aerodynamic advantages for eyewear. These new sunglasses are shaped to fit closely to the face and help direct airflow away from the ears, supporting efficient air management over the shoulders and enhancing the rider's aerodynamic profile. The sunglasses are equipped with Clarity lenses for always-sharp vision and are made from a biogrilamid frame. The package includes three sizes of nose bridge, ensuring every user finds a comfortable and secure fit. The temples are fully adjustable in both length and grip for absolute comfort.
