Highlights Biogrilamid frame Complete UV protection Clarity lens technology Trailing edge on lens Adjustable temples Description The result of CFD (computational fluid dynamics) testing, the Propel sunglasses introduce the concept of aerodynamic gains to eyewear. Shaped to sit close to the face and to help push air away from the ears, the new sunglasses use a trailing edge on each Details A wide lens gives an exceptional field of view with no obstruction from the frame.

Easily swap lens to a different tint to always have the best vision in different light conditions. Lenses with Clarity technology for sharper vision are available. A distinct trailing edge at each end of the lens directs air away from the ears and over the shoulders for improved aerodynamics. Both the length and the grip of the temples are easy to change for a personalised fit. Ri-Pel™ protects from dirt, water, sweat, salt, oil and dust, and makes the lenses easier to keep clean.
