Giro Air Attack Road Helmet With Shield

Giro Air Attack Road Helmet With Shield 2014

Until now, you couldn't really have all three of these attributes in a single design. Aerodynamic efficiency was compromised by ventilation. Weight was compromised by cooling or the added weight of longer, aerodynamic designs.

The Air Attack ends the compromise.

The Air Attack™ is a whole new form of helmet, combining a compact aerodynamically-optimized design with a revolutionary ventilation system that matches the cooling power of strategically-placed vents and internal channels with enhanced airflow via the Roc Loc® Air system. The combination of light weight and aerodynamically-efficient design plus highly-effective cooling means that a rider's body not only encounters less drag, but also has more energy available for generating power, enhancing the rider's overall efficiency.

For road racing, criteriums and long solo efforts, the Air Attack™ slices through the wind with 97% of the cooling efficiency you get with Giros ultra-light, ultra-cool Aeon™ helmet, and 11% less wind averaged aerodynamic drag.

For triathlon and long-distance time trials, the Air Attack™ Shield offers 28% more cooling power with only a 11% increase in the wind averaged drag compared to our Selector™ helmet, which has the lowest drag of any production aero helmet with an optical shield we've tested (in fact, less drag than a bare headform).

The result? A helmet you can use for more types of riding, and that allows your body moves through the air with less resistance, and a more efficient engine, giving you a boost of free speed.

It's a revolution in helmet design and performance, from the leader in helmets, Giro®.

X-Static Anti-Microbial Fabric - X-Static fibers are made with layers of pure silver that are woven into the fabric. Silver offers 100% natural anti-microbial performance that helps to reduce odor and regulate heat, so your feet stay fresh and comfortable, naturally. In addition to being plush and comfortable, our X-Static pads provide anti-microbial properties to help keep your helmet fresher, longer. The pads are also machine-washable.

Roc Loc Air Fit System - The revolutionary Roc Loc® Air system enhances comfort and stability while adding a new dimension to ventilation and cooling. With a unique design that suspends the helmet slightly above the head, it creates an optimized path for air to flow through the helmet with a Venturi effect that increases efficiency of the vents and internal ventilation channels. Like the acclaimed Roc Loc®5, it also offers micro-adjustable tensioning and vertical positioning adjustments, so you can fine-tune the fit and tilt on the fly with one hand. It's a new level of skull-hugging luxury and cool that only Giro can provide!

Wind Tunnel Ventilation - Giro helmets are developed utilizing our proprietary Wind Tunnel™ ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the rider's head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.

In-Mold Construction - Giros In-Mold construction process fuses the helmet's outer shell with its impact-absorbing EPS liner during the molding process, making the liner literally a part of the helmet. This fusion process reinforces areas around vents and ribs, creating a one-piece 'exoskeleton' that allows the helmet to be lighter, more durable, and better ventilated than traditional designs.

Super Fit Construction - A great helmet is so comfortable that once it's on, it virtually disappears. Giros proprietary three-size Super Fit system is based on “human scale factors” data and over 20 years of crafting helmets for the best bike riders in the world. The result is pure Skull Hugging Luxury™, a helmet that fits 98% of the world's population, yet looks (and fits) like it was custom made just for you.
