Giro

Frequently Asked Questions

• What helmet technologies does Giro use to reduce rotational and linear impacts?

  Giro combines multi-directional impact protection with energy-absorbing EPS liners and MIPS systems—including Spherical MIPS variants on many snow helmets—to manage rotational forces, while in-mold polycarbonate shells and EPS handle linear impacts. These layered systems work together to reduce brain strain from oblique impacts and improve overall crash performance.
• How does Giro’s Roc Loc fit system work and which helmets use it?

  The Roc Loc system is a dial-adjustable cradle that tightens the fit around the head for secure retention and micro-adjustability; variants include Roc Loc Air and Roc Loc 5 for lighter, ventilated setups. Roc Loc systems appear across Giro’s road and mountain lines, including popular models like the Synthe (road) and Talon (MTB).
• What distinguishes Giro’s road helmets from their mountain-bike and snow helmets?

  Road helmets such as the Synthe prioritize aerodynamic shaping and long-channel ventilation for high-speed comfort, while mountain helmets like the Talon emphasize greater coverage, visor integration, and trail-oriented ventilation. Snow helmets typically add Spherical MIPS options, enhanced goggle compatibility, and thicker liners for cold-weather protection.
• How does Giro design ventilation and comfort into its helmets?

  Ventilation relies on purpose-built internal channels within in-mold polycarbonate shells and strategically placed vents that move air over the EPS liner to cool the head, with some models tuned for aero vs. maximum airflow. Comfort is enhanced with removable, antimicrobial, sweat-wicking liners and padding that are replaceable on many Giro helmets.
• What materials and build choices does Giro use to improve durability and lifespan?

  Giro uses in-mold polycarbonate shells bonded to EPS liners for a lightweight but durable shell-to-liner bond, plus robust retention systems like Roc Loc and replaceable interior pads to extend usable life. The brand continually refines materials and manufacturing to reduce weight and improve impact performance while maintaining serviceability.
