With its vented lens, SIERRA manages vision-robbing condensation, while providing comfort and optical performance at the same time.
- Embedded premium anti-fog layer in the inner lens disperses water molecules across the surface of the lens, restricting moisture build up that can impede your crystal clear view of the terrain ahead
- Creation of a dual-pane thermal barrier between the cold dry outside air and the moisture generated by intense activity prevents distracting condensation from forming
- A high-tech protective armor applied to the outer lens creates a shield to significantly reduce scratching, keeping your lens and outlook as clear as a bluebird sky
- Sport Optical System lets you easily snap in a prescription lens adapter without affecting your wide field of view
- Medium density foam backs up a soft micro-fleece face layer
- Bolle lens block harmful UVA/UVB rays up to 400 nanometers
