The new collection of sunglasses from Ermenegildo Zegna (zegna.com) includes these rimless aviator ($380, left) and vintage wayfarer ($295, right) models. The aviators fold at the bridge and come with a leather carrying case. The temples are made of lightweight titanium, and the lenses are produced by the 169-year-old German optics company Zeiss. The wayfarer model’s frame is made of acetate and is available in four colors. Both models display the Zegna logo on the temples.
