Overview

KOO Spectro Sunglasses are engineered for speed-focused cyclists who demand coverage and clarity during fast road rides, triathlon time trials, and high-intensity training. The large single-lens design offers an expansive, unobstructed field of view, while the frame shape ensures a stable fit even when riding aggressively in the drops.

Optics & Clarity

The sunglasses utilize a ZEISS® polycarbonate shield enhanced with ZEISS® Anti-Reflective Technology to minimize reflections and improve contrast and definition. This reduces glare and eye fatigue, providing sharper vision in bright or variable lighting conditions.

Ventilation & Fog Control

Integrated ventilation ports—four in total—help maintain airflow across the lens surface to reduce fogging during climbs and humid conditions, ensuring clear vision throughout your ride.

Fit & Comfort

Designed as a one-size-fits-most, the Spectro offers approximately 140 mm width and 125 mm temple length (varying slightly by colorway). The broad shield lens provides high coverage without a lower frame edge, keeping your view clear when tucked in an aerodynamic position.

Lens Options & Serviceability

Spectro supports replacement lenses, including photochromic options, allowing riders to adapt to changing light conditions or replace damaged lenses without buying a new frame.
