ST5 Visor Dark Iridium Blue

The ST5 Visor Dark Iridium Blue is a premium helmet shield designed for drivers who demand superior optical clarity and safety under high-intensity lighting conditions. Built as a direct replacement visor for STILO ST5 helmets, this anti-fog shield protects your eyes from glare, UV exposure, and environmental debris while maintaining the visibility critical to competitive driving, road courses, and professional motorsport environments. Whether you're logging track time or navigating variable weather conditions, this dark iridium visor reduces light transmission and minimizes eye strain during extended driving sessions.

The dark iridium blue coating works by reflecting and absorbing excess light across the visible spectrum, making it especially effective in bright daylight and high-contrast environments where conventional clear shields cause glare fatigue. The anti-fog treatment applied to the interior surface prevents condensation buildup, maintaining optical clarity during rapid temperature changes—critical when transitioning from a climate-controlled pit area to open-track conditions. The visor measures 7.5 x 6.4 x 10.05 inches and weighs just 0.36 lbs, engineered for a secure fit on ST5 helmet models while remaining lightweight enough to eliminate neck fatigue during long driving sessions. The polycarbonate construction delivers impact resistance without compromising optical quality.

This visor is essential for serious drivers who own STILO ST5 helmets and regularly encounter bright sunlight, high-speed cornering, or variable track lighting. Professional racers, amateur competitors, and track-day enthusiasts benefit from the reduced glare and consistent visibility that dark iridium optics provide—particularly in morning or late-afternoon sessions when sun angle creates extreme contrast. Installation is straightforward: the visor simply clips into the ST5 helmet's visor mechanism without tools or modification. Keep a clear shield backup visor for overcast or low-light conditions to maximize your optical options across all weather scenarios.
