Reaches Cat 3 glacier density of 88% (12% VLT) at full darkening. A more aggresive, higher contrast version of the basic McKinley starting at a 40% density in lower light moderate to cool temperatures and transitioning to marginal glacier density in brighter conditions. An excellent rapid sport lens, with some flexibility for other applications. CAUTION! Extreme cold will also activate darkening even in lower light conditions.
