Oakley® Kaast arrives as the brand's first dual-lens sunglass enabled by PhysioMorphic™ Geometry, the design methodology first introduced in Oakley™ Kato. This innovation allowed for the creation of a first-of-its-kind lens to lug design aesthetic featured in the style. The O Matter™ frame material is tuned for optimized fit and head retention while a 3-point fit provides all-day comfort. Unobtainium® nosepads are attached to the lens, creating a unique bridge aesthetic with no-slip grip and Prizm™ Lens Technology to enhance color and contrast across a variety of environments and activities.
