Fit & Comfort
This sunglass offered a comfortable fit for my small- to medium-sized face. It slipped on seamlessly but the frame’s smaller design did create a tiny amount of discomfort, especially on the nose bridge, during longer activities. At the same time, the gripping nosepads and temple ends worked extremely well to hold this sunglass in place, even during highly technical trail riding and running excursions.

Lens Clarity
The Cervin served up excellent optics, courtesy of Bolle’s b-Clear lenses made with the strong, light, and visually crisp Trivex lens material.

According to the company, Trivex outperforms polycarbonate as a lens material in shatter-resistance and clarity. I didn’t test the shatter-resistance of these lenses, but the optical quality of the lenses was noticeable. I did, however, experience a small amount of reflection in the lenses when looking down the trail into the direction of the sun.

The Cervin’s lenses are also treated on both sides with a hydro- and oleophobic (water and oil repellant) coating that repels grime, grease, and water and we found this feature to work quite well. I rarely found myself cleaning these lenses.

Wind Resistance
The Cervin’s full-coverage wrap design kept the sun and wind out and a venting system located near the temple endpieces also helped minimize sweat and lens fogging.
