Prada Linea Rossa

Prada Linea Rossa is the eyewear-focused line that carries the red stripe, a mark that used to identify Prada Sport. The name nods to Luna Rossa, the yacht that races in the America's Cup, and the look follows from that: high-tech and minimalist, with nothing added for show.

The range centres on technical sunglasses, including wraparound styles. The idea is to balance elegance and engineering, so the frames work as everyday glasses rather than something kept for the sailing season. If you want sunglasses that look sharp and clean but are clearly built with function in mind, this is a good place to start. The red stripe is the quickest way to spot a pair across a room.
