About Giro Synthe MIPS Road Helmet - Highlighter Yellow

Comfort, aerodynamics and ventilation are perfectly synchronized in the Giro Synthe Road Helmet.

The Giro Synthe... is now available with Multi-DIrectional Impact Protection System (MIPS)!

MIPS allows for the Synthe to absorb shock much more effectively than traditional helmet designs due to the sliding webbing layer within the outer polycarbonate shell, which moves in the case of impact. This allows the helmet to absorb a greater amount of shock from the impact because not only does the outer shell take the blow, it does this without transferring it to the head of the user.

The Synthe is the pinnacle of road helmet design. It offers impressive cooling power, minimal weight, supreme fit and streamlined aerodynamic efficiency. It is a true synthesis of all features a modern rider wants in a high performance road racing helmet. 

The difference is clear in the wind tunnel—our extensive testing reveals that the Synthe is nearly as efficient as the fastest time trial helmets. But the Synthe’s greatest attributes are comfort and ventilation. At it’s heart you’ll find our Roc Loc Air fit system. Micro adjustments allow you to custom tune tension and fore-aft tilt with one hand and a patented design suspends the helmet over the top of the skull, allowing airflow to pass freely over your head. Cooling power is further boosted by elaborate internal channeling and a series of massive vents; the Synthe sets a new bar for ventilation. 

You no longer need to choose between aerodynamics and cooling power—with Synthe you get everything, all wrapped up in a compact and sleek silhouette.


The Roc Loc Air system enhances comfort and stability while adding a new dimension to ventilation and cooling. With a unique design that suspends the helmet slightly above the head, it creates an optimized path for air to flow through the helmet with a Venturi effect that increases efficiency of the vents and internal ventilation channels. Like the acclaimed Roc Loc 5, it also offers micro-adjustable tensioning and vertical positioning adjustments, so you can fine-tune the fit and tilt on the fly with one hand. It’s a new level of skull-hugging luxury and cool that only Giro can provide!
