Overview

KOO Spectro Sunglasses are designed for speed-focused riding where coverage and clarity matter most—fast road days, tri/TT sessions, and high-output training. The large single-lens silhouette delivers a wide, unobstructed view, and the frame shape is built to stay steady when you’re in the drops or turning at pace.

Optics & clarity

Spectro uses a ZEISS® polycarbonate shield and is offered with ZEISS® Anti-Reflective Technology to reduce unwanted reflections and improve perceived contrast and definition. The goal is simple: less glare, less eye fatigue, and sharper vision when light is harsh or changing.

Ventilation & fog control

Fogging is handled with integrated lens ventilation. KOO’s product description calls out engineered vents, and replacement-lens spec sheets reference four ventilation ports to help keep air moving across the lens surface during climbs and humid conditions.

Fit & comfort

Spectro is typically listed as a one-size fit with references around 140 mm overall width and 125 mm temple length (some colorways list slightly different widths). The broad shield gives high coverage without a lower frame edge, helping keep your view clear when you’re tucked.

Lens options & serviceability

Spectro supports replacement lenses, including photochromic options in some ranges, so you can tune the setup for your riding conditions or swap a damaged lens without replacing the entire frame.
