Giro Bike Helmets: protection and performance for every ride

Road cyclists chasing speed, mountain bikers tackling rugged trails and parents choosing a first bike helmet for their child all know that the right helmet makes the difference between a good ride and a great one. At Giro Sport Design, safety, design and technology come together in every bike helmet to deliver advanced protection, comfort and confidence, no matter where or how you ride.

Choose the right helmet for your riding style

Different rides call for different levels of coverage, ventilation and features. Giro designs bike helmets to match specific terrains and riding priorities, helping every rider find the right balance of protection and comfort. Once you've matched a helmet to how you ride, fit comes next, followed by technology such as MIPS® or Spherical Technology™ for added rotational impact protection.

• Road Bike Helmets – Built to balance ventilation and efficiency for long rides, fast efforts and everyday training on paved roads.
• Gravel Bike Helmets – Versatile protection for mixed-terrain riding, combining airflow and coverage for changing conditions.
• MTB Helmets – Designed for off-road control and confidence on technical trails, with options for increased coverage and impact management. For more demanding riding, explore Full Face MTB Helmets for maximum protection.
• Kids Bike Helmets – Secure and comfortable helmets created specifically for young riders, with easy adjustment and all-day comfort.
• Urban Bike Helmets – Commuter-focused designs that prioritise visibility and comfort for city traffic, low light and frequent stops.
• Scooter Helmets – Everyday protection for short-distance trips and urban mobility.

For additional coverage from sun, rain or trail debris, you can also explore Bike Helmets with Visor, a practical option for everyday riding and changing light conditions.

Still weighing up fit, technology or budget as well as discipline? Our guide on how to choose your Giro cycling helmet walks through all of it in one place.

Cutting-edge cycling helmet technologies for safety and comfort

Giro bike helmets are developed using advanced technologies that enhance protection, improve fit and increase comfort across a wide range of riding styles.

• MIPS® (Multi-directional Impact Protection System) – A slip-plane system designed to help reduce rotational forces during angled impacts.
• Spherical Technology™ – A dual-layer ball-and-socket design powered by MIPS® that allows the outer shell to rotate independently of the inner shell, helping redirect impact forces while maintaining ventilation and comfort.
• DryCore™ Sweat Management System – A lightweight brow pad with an integrated silicone bead that helps redirect sweat away from the eyes.
• Halo System Chinbar – A chinbar system that combines Pebax® and elastomeric bushings integrated into the EPS to help absorb and dissipate kinetic forces in full-face designs.
• IONIC+™ Padding – Padding that uses pure silver for natural and long-lasting odour protection.
• ROC LOC® Air Fit System – A fit system that helps the helmet sit securely while allowing airflow over the scalp for improved cooling.
• Super Fit Engineering – Giro's sizing approach developed to deliver a secure and comfortable fit across multiple sizes.

Frequently asked questions

Do you have to wear a helmet on a bike?

Helmet laws vary depending on where you ride, so it's worth checking your local regulations. Even where it isn't a legal requirement, wearing a properly fitted bike helmet every time you ride is strongly recommended, since it's your primary protection against head injury in a fall or collision.

How should a bike helmet fit?

A bike helmet should sit level on your head, about one to two finger-widths above your eyebrows, and feel snug without pressure points. The side straps should form a V just under each ear, and the chin strap should allow only one or two fingers between it and your chin once fastened. To measure, wrap a tape measure around your head just above the ears and eyebrows, and match that measurement to the manufacturer's size chart.

What is the difference between road and mountain bike helmets?

Road helmets are lighter and more compact, built for maximum ventilation and aerodynamics on paved surfaces. Mountain bike helmets offer more rear-head and side coverage, often with a visor, to protect against low branches, trail debris and the higher-impact conditions of off-road riding.

What does MIPS mean and do you need it?

MIPS® is a slip-plane layer built into the helmet's protection system, learn more here. It's not a legal requirement, but it's a meaningful upgrade for riders who want an added layer of protection against the rotational forces common in real-world falls, over and above standard certification.

What is a helmet visor for?

A visor shields your eyes from sun, rain and low branches or trail debris, which is why it's standard on most MTB helmets and optional on road and urban designs. It can usually be removed on models where a cleaner, more aerodynamic profile is preferred.

How long do bike helmets last?

A bike helmet should be replaced immediately after any crash or significant impact, even if there's no visible damage, since the foam liner can be compromised internally. Without an impact, most manufacturers recommend replacing a helmet every three to five years, as UV exposure, sweat and general wear gradually degrade the foam and straps.

How do you clean a bike helmet?

Wipe the shell and padding with a damp cloth and mild soap, then let it air dry away from direct heat or sunlight. Avoid machine washing, submerging the helmet or using solvents and harsh detergents, which can damage the foam liner and its protective properties.
