Sortie is a classic aviator sunglass. Its frame is made with extremely light and incredibly strong Titanium, a material widely used in aeronautical applications. Ultra-Light glass lenses and highly adjustable nose pads deliver the performance and comfort pilots demand and anybody else can appreciate. Sortie was designed in partnership with Major Dan Rooney, former F-16 Fighter Pilot and founder of the Folds of Honor Foundation, an organization providing assistance to the families of fallen or disabled US soldiers. For every Sortie sold in the US, Serengeti will make a donation to the Folds of Honor Foundation to help those in need.
