Dark Lens
Perfect all-round lens choice for everyday partly sunny lighting conditions. These lenses significantly reduce light transmission and glare on the eyes, while maintaining natural contrast for clear vision during partly sunny days.

Functions:

• DuoCurve - A combination of spherical and cylindrical lens curve that allows panoramic, distortion-free vision both laterally and vertically.
• Cool Inject Frameless - A cool silicone injection directly onto the lens for an ultra-lightweight frameless construction, allowing greater hydrodynamics and less drag.
• Low profile and larger field of view - The DUOCURVE lens technology together with the compact skirt provides a wider field of view. Compared to VISTA Pro, DEFY Ultra offers a larger field of view in all directions.
• PFT (Precision fit Technology) - Ultra-thin silicone for ultimate fit and comfort
• Quick Fit Buckle 2.0 - Quick and secure adjustment
• Ergonomic nose piece - Reduce drag
