With It's Aerodynamic Shape, Low Weight And Great Ventilation The New Giro Synthe Is Without Doubt One Of The Best Performing Helmet On The Market For 2015.


The new Giro Synthe helmet is the perfect choice for any rider who is looking for a helmet that is suitable for all riding conditions. The helmet offers impressive cooling, minimal weight, supreme weight and aerodynamic efficiency. Giro claim that the Synthe is 16% faster and 2% cooler than their existing lightweight Aeon helmet, and 13% lighter than the Air Attack.

Constructed around a in-mold polycarbonate shell with EPS liner the Synthe features the Roc Loc Air fit system which enhances both comfort and stability while creating new dimensions when it comes to ventilation and cooling. The design of this system is unique and offers micro adjustments allowing you to custom tune tension with just one hand while the helmet suspends slightly above your head which creates an optimized path for air to freely flow over your head. Cooling is further aided by the inclusion of 19 vents with internal channeling which do a great job of providing a constant air flow at all times. Internally the helmet features X-Static padding which contains a fibre made with layers of pure silver that is permanently woven into the fabric. Silver has a natural anti-microbial performance that helps to reduce odor and regulate heat, so your helmet stays fresh and comfortable, naturally.


Small: 51-55cm
