MTB Helmets

MTB helmets built for demanding trails

Attention trail seekers. Whether you are chasing cross-country speed, tackling technical enduro descents, riding all-mountain terrain or committing fully to downhill lines, Giro designs MTB helmets for riders who thrive on rough and unpredictable trails.

At Giro Sport Design, we create certified MTB helmets engineered specifically for protection, stability and performance. From long climbs to fast and technical descents, our mountain bike helmets are built to keep you protected and confident on every trail.

Giro commitment to mountain bike helmet protection

Mountain biking places unique demands on head protection. Giro MTB helmets are designed with deeper coverage than road helmets, particularly around the back of the head, to enhance protection in the occipital area.

Whether you choose an open-face design for trail riding or a Full Face MTB Helmet for downhill and gravity-focused disciplines, Giro applies the same design principles across the range. In-Mold construction creates a strong bond between the EPS foam liner and the outer shell, helping absorb impact energy while keeping weight low.

Many Giro MTB helmets also feature integrated visors to protect against sun, low-hanging branches and trail debris. Adjustable fit systems and enhanced ventilation ensure a secure, comfortable fit that stays stable even on rough terrain.

MTB helmets for every riding discipline

Giro offers mountain bike helmets designed to match different riding styles, from lightweight trail helmets to full-coverage gravity protection.

For downhill and BMX riders who demand maximum coverage, the Coalition Spherical stands out in the full-face category. Designed for high-speed riding, it delivers exceptional protection while maintaining a lightweight feel. Spherical Technology powered by MIPS helps manage rotational forces during impacts, while efficient ventilation channels keep riders cool during intense sessions.

Trail riders who prefer the freedom of an open-face design will appreciate helmets like the Radix MIPS. Built to balance rugged durability and comfort, it features the Roc Loc 5 MIPS fit system for a secure, adjustable fit and Wind Tunnel ventilation to manage airflow during demanding climbs.

The Fixture MIPS II offers another open-face option, combining classic styling with dependable protection and excellent value. Its updated shape, quick-dry padding and reflective rear details make it suitable for both casual trail rides and more challenging terrain.

For riders seeking added coverage without stepping into a full-face design, the Artex MIPS delivers a refined balance of protection and ventilation. Its slightly deeper profile, removable visor and Roc Loc 5 Air MIPS system provide stability and comfort over long rides.

The Source MIPS rounds out the range with a trail-ready design focused on durability and airflow. Deep coverage, aggressive ventilation and an adjustable moto-style visor make it a reliable choice for riders tackling technical and demanding trails.
