Hotly anticipated, the Giro Synthe Helmet 2017 features 19 vents and internal ventilation channels, an ingenious Roc Air fit system, X-Static® padding and a Wind Tunnel-Aided design. All this makes it one of the fastest, best-ventilated helmets on the market.

Giro Synthe Helmet 2017

Ridden to Grand Tour stage victories, used by some of the fastest riders in the world, the Giro Synthe Helmet 2017 is lightweight, aerodynamic and well ventilated. Offering more ventilation than Giro's Air Attack helmet, the Synthe is still a fast helmet against the clock, with its Wind Tunnel-Aided design.

Fitting impeccably, the Roc Loc Air fit system provides micro adjustment, allowing you to adjust fore-aft tilt with one hand on the move. This pioneering fit system suspends the helmet over the head, thus improving airflow. Further adding to this helmet's excellent ventilation credentials are the carefully placed internal channels and large vents. This makes the Synthe the perfect choice for when the temperature rises in sportives and races.

Ridden by the likes of super climber Joaquim Rodríguez, the Synthe is a climber's delight. Weighing a mere 240 grams in its medium size, there is no excuse for being dropped on a climb wearing this.

Sunglasses on or off, the Eye Wear Docking Ports provide a secure area to store your glasses when you are not wearing them.

A helmet for long rides, the X-Static® padding is discrete, washable and breathable. The lightweight webbing is non obtrusive, with a Slimline™ buckle providing a secure closure. This is easy to use with one hand and makes adjusting the strap length a simple task.

With 19 vents, in a range of stunning colours, all with subtle graphics, the Giro Synthe is one of the most exciting helmets on the market.

Please note: Helmets that are sold on are certified with a European CE EN1078 standard. Specific countries may have their own certification, which is legally required. Please check your specific country requirements and check with the manufacturer to see if the helmet has received any additional certification.
