The Giro Synthe is the pinnacle in Giro's helmet design. This modern helmet has impressive cooling performances, minimal weight, a perfect fit, and a sleek aerodynamic efficiency. This helmet makes a big difference during extensive wind tunnel tests. These tests clearly showed the Synthe is as aerodynamic as most time-trial helmets. The best features of this helmet are comfort and ventilation. In the heart of the helmet you will find the Roc Loc Air Fit System.
With this system the helmet is slightly suspended over your head, so as to create an optimal air flow. It is possible to adjust the tension and the front or rear overturning. You no longer have to choose between aerodynamics and ventilation: with the Synthe you have it all!
Feels like a top end product i had an accident in this helmet and it saved me from serious head injury
full price would be expensive

Superb cycling helmet
Looks fantastic, really light weight, very comfortable and my head remained cool even on tough 100 mile route recently.
Mantel company I can’t praise enough. Really easy purchase, informative emails kept me up to date with tracking and a final thank you message for using them. I will definitely use Mantel in the future for further cycling gear and would definitely recommend to others.
Great price from Mantel
Keeps your head nice and cool

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!!
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.
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.
