Shop Giro Helmets

Born on the road, Giro defines premium head protection for riders big and small. Engineered with cutting-edge impact protection, Giro helmets bring pro-level safety for weekend warriors and peace-of-mind for families letting littlies roam.

From lightweight road styles to rugged Mountain Bike coverage and colourful kid-friendly builds Giro scales its tech so every rider gets a helmet they trust, not just admire.

The Giro Story

Founded in 1985 by Jim Gentes, Giro started with a keen eye for design and filling gaps nobody knew existed—footwear lasts that felt right, helmets that balanced protection and comfort. It has grown into a brand celebrated for innovation, rigorous testing and a passion for riders of all kinds.

Giro uses those same roots—originality and precision—to make helmets that protect on every ride today. You benefit when every vent, fit system and shell material is born out of decades of design practice and scientific safety standards.

Why Ride Giro?

Rotational impact protection built in. Giro integrates the Multi-Directional Impact Protection System to reduce brain-damaging torque during angled crashes so you ride safer on road, gravel or trail.
Fit systems designed for every head. From Roc Loc Sport to Roc Loc Junior, Giro offers easy one-hand adjustments, secure dials and scaled sizes so you get a stable, comfortable fit whether you're 5 or 50.
Strong shells without unnecessary bulk. In-Mold and Hardbody constructions use polycarbonate fused to foam to protect without heaviness or awkward shapes.
Ventilation and sweat control matter. Wind Tunnel vents, internal channels, quick-dry and anti-microbial padding help you stay cool and clean when the temperature or the ride heat up.
