As a modified version of the traditional aviator, Ballmer adds a touch of classic style with an updated metal frame style. A new, slightly curved (6 base) and lightweight frame chassis features adjustable, hypoallergenic nose pads and acetate temple tips, accented by inlayed metal Kaenon logos — subtle details that allow Ballmer to seamlessly fit into the Kaenon lineup. Designed to fit a wide range of face shapes and sizes.
