Pros & Cons

  • The MIPS system reduces the shock of a crash substantially, increasing head safety.
  • Aerodynamic yet well ventilated due to the 16 vents.
  • The helmet is raised fractionally above your head due to the Roc Loc 5 adjustment system, creating even more ventilation.
  • The X-static Padding has antibacterial properties, making the helmet stay fresh longer.
  • Despite the helmet’s good protective qualities the finish could have been better.
  • The Roc Loc 5 adjustment system feels a bit fragile for a bicycle helmet of this grade.

All specifications


The Giro Synthe Mips is the pinnacle of Giro's helmet design. This modern helmet offers impressive cooling performance, minimal weight, a perfect fit, and sleek aerodynamic efficiency. The difference really showed during Giro's extensive wind tunnel testing. In fact, the Giro Synthe proved to be as aerodynamic as numerous time trial-specific helmets! The best properties of the Synthe: comfort and cooling. At the heart of the helmet is the RocLoc Air Firt system. This system raises the helmet fractionally above your head, creating enough space for air to flow through. This system also allows you to adjust the tension on the head band as well as the forward/aft tilt. No longer be faced with a choice between aerodynamics and cooling: the Giro Synthe can do both!

Everything you need in one helmet

Best helmet I’ve ever owned. Lightweight, greatest of quality build, beautiful to look at and already in love with it. Everything you need in a helmet, good aero features but also great for climbing or casual riding. It’s so comfy you don’t even notice you’re wearing a helmet.

Detailed product description

Roc Loc Air Fit system:
The Giro Roc Loc Air system is specially developed for the Giro Airo helmets. This new system ensures the helmet floats a little bit above your head. As a result there is a good airflow over the top of your head what ensures a good ventilation. Just like the Roc Loc®5 system the helmet can be easily fine-tuned. The tension around the head and the vertical position can be adjusted with one hand. With this Giro sets the new standards for ventilation and comfort.

MIPS System:
The MIPS System exists out of a low friction interlayer between the EPS lining and padding with an elastic fixation. This allows the helmet to move (slide or rotate) during a crash. It will move around your head to catch the side and rotational forces that could occur during a crash. This in contrast to a helmet without MIPS, whereby the impact is only collected by compressing the EPS lining.

Wind Tunnel Ventilation:
Giro helmets are developed using its Giro Wind Tunnel ventilation system. This system combines the active vents with the internal ventilation outlets. This combination ensures a cool, fresh air flow over and around the riders head, while forcing the heat and stale out. The renewing of these ''air channels'' turns out to be a huge success. The riders were real enthusiastic, they noticed the new ''air flow'' around their head, resulting in a better cooling!!

In-Mold Construction:
The In-Mold Construction combines a strong polycarbonate outer shell with
shock absorbing helmet padding. Thanks to its fusion process it is possible to sculpt a better ventilation system, so the In-Mold helmets are lighter and cooler than most traditional helmets.

X-static Padding:
Besides the fact they are comfortable The X-static pads ensure anti-microbial properties to keep your helmet longer clean . The pads are machine washable.
