The Giro Synthe Mips is the pinnacle of road bike helmet designs. This helmet combines the performance advantage of aerodynamics and light weight with excellent cooling. Increasing comfort and aerodynamics.

The compact shape and Aero Mesh panels increase aerodynamics.
The compact form enhances air flow around the Giro Synthe MIPS while the Aero Mesh panels on the side of the road bike helmet give an extra boost to its already excellent aerodynamics. Another cool feature are the special slots so you can easily and securely place your cycling glasses on the helmet.

26 air vents and Roc Loc Air Fit System for optimal ventilation
The 26 air vents incorporated in the Synthe give it a superb ventilation system. Additionally, the Aero Mesh panels have small holes in them to further improve ventilation. 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.

The MIPS technology reduces the risks of a concussion.
The Synthe MIPS consists of an In-mold polycarbonate outer shell with EPS liner. In order to guarantee optimal fall protection, the MIPS technology has been added to this bicycle helmet. The MIPS system consists of a low friction interlayer between the EPS liner and the padding, which is provided with elastic fasteners. This allows the helmet to move slightly in relation to the head in the event of a fall. This ensures that lateral and rotational forces are better absorbed. The positive result of this is a considerably lower risk of concussion.

The lightweight straps with Slimline Buckle and the antibacterial X-static Padding, complete this cycling helmet. You no longer have to choose between aerodynamics, cooling and safety. With the GIro Synthe MIPS you have all these qualities in one helmet! No longer be faced with a choice between aerodynamics, cooling or safety: the Giro Synthe has it all!

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

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.

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.

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.
