SUPER FIT™ ENGINEERING GOGGLES
Super Fit Engineering is the foundation of our product design process. Every new Giro product is designed with reference to our database of anatomic measurements and rider input. We then test the design repeatedly in the lab and in the hands of riders so we can gather feedback and make refinements to create a final product that fits and performs at the highest level.
INJECTION MOLDED CYLINDRICAL LENS
Injection molding a cylindrical lens helps refine optics and minimize distortion that can occur subtly in thermo formed cylindrical lenses. We offer a full range of performance-engineered lens tints and mirror coatings that help to enhance your vision and every lens is protected by a durable hard coating that resists scratches.
Every Giro goggle lens features our anti-fog coating to keep your vision and riding experience on point.
Vents cut into the lenses above the gasket line allow warm air to escape and keep your goggle from fogging.
Giro offers a full assortment of performence-engineered polycarbonate lenses in a wide range of lens tints to enhance your vision in conditions ranging from blue bird, to full storm. Every lens filters 100% of harmful UV, and features durable coatings that resist fogging and scratches. Select lens tints include flash mirror coatings that tune light transmission for optimal vision.
