Giro Synthe MIPS Road Helmet 2019
The Giro Synthe MIPS road helmet is the pinnacle of design, combining the performance gains of aero efficiency and lightweight with great cooling power to enhance your comfort and efficiency.
The compact form slips through the air with ease across multiple yaw and head angles and offers greater cooling power than the Aeon.
Key features include the Roc Loc Air fit system with 2-way fit tuning and Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride. Synthe MIPS models are available with the Multi-Directional Impact Protection System. We believe MIPS can redirect energy and provide more protection in certain impacts.

MIPS
All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards.
The goal of Giro’s MIPS-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider’s brain in certain impacts. Learn more about MIPS in the video above.
ROC LOC AIR FIT SYSTEM
This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet.
Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
Occasionally, without notice, manufacturers change product design and/or specifications.
Giro Helmet Size Guide
How to measure your head size
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.
Giro cycling helmets are adjustable so will fit a range of head sizes. Once you know the circumference of your head, select an appropriate helmet size. For example, if your measurement is 57cm then a size M (55-59cm) or a One Size (54-61cm) will fit you.
