Inspired by Formula 1 and downhill ski racing helmets, the Giro Aether MIPS boasts an entirely new level of helmet technology.

Up until now, bicycle helmets have been largely similar in their construction: Plastic outer layer, EPS/styrofoam liner and soft padding. With a few improvements in how many vents it had, and how much force it could absorb while strapped to a mannequin, little had changed since the late 80's. Giro decided to take the recent concept of a Multidirectional Impact Protection System -or MIPS- liner and redesign the helmet from the ground up. Three years in the making, the result is the Aether with MIPS Spherical.

MIPS Spherical replaces the thin plastic MIPS layer with a second layer of lower-density EPS styrofoam. This allows the helmet to absorb an impact more progressively while retaining the ability to absorb oblique impacts better. Attaching the two layers of EPS are the same elastomers found in a regular MIPS helmet. Because the two EPS layers are fitted in a hemispherical ball-and-socket design, the Aether MIPS will absorb a given impact's energy in a wider range of angles. Hence the name: MIPS Spherical.

The EPS styrofoam found in the Aether MIPS is now a different "recipe" called nanobead EPS. Much more complex shapes could be molded with nanobead EPS, allowing Giro's design team to create a sleeker, more aero helmet while retaining all the safety that MIPS Spherical provides. Giro also built a thin shatter-resistant reinforcing arch into the helmet's outer EPS shell called AURA. The AURA arch allowed the Aether MIPS to be built with 11 very wide Wind Tunnel vents, improving ventilation on hot days. The exterior shell of the Aether MIPS is built from 6 laser-cut pieces of polycarbonate that make the helmet more resistant to major impacts and daily dings. Even the Giro logo is raised polycarbonate instead of a sticker. There are textured eyewear docking ports in the forward vents of the Aether MIPS, offering a good place to stow your shades on hot climbs. All this technology should make the Aether MIPS a heavy piece of equipment on the rider's head. In fact, the Aether MIPS is actually 20 grams lighter than the previous Synthe MIPS flagship helmet in the same size.

The interior fit of the Aether MIPS can be adjusted with Giro's familar Roc Loc 5+ Air fit system. With the proven design of the Roc Loc Air fit system, ponytails are no problem with the Aether MIPS. One-hand adjustment makes on-the-fly fit tweaks simple, and the ultralight webbing and slimline buckle does the best job of all: Helping you forget you're wearing a helmet.

Giro's Aerohead MIPS takes the same wind-cheating silhouette as the leading-edge Aerohead Ultimate, but adds increased ventilation to keep triathletes and time trialists cool when the competition is hot. By rethinking the wearer's head position into the middle of the helmet, the angle of the helmet is less disruptive of airflow. No need to hold an aggressive position for a full-length IronMan to achieve low drag numbers! By using a polycarbonate shell, Wind Tunnel ventilation, and internal channeling, this helmet is proven to boost cooling power while remaining aerodynamic. Additionally, Aerohead MIPS features a wrap-around eye shield that offers an impressive field of view with the convenience of a magnetic anchor attachment to allow easy storage of the lens in the "flipped up" position—perfect for fast swim-to-bike transitions. A Roc Loc 5 Air retention system brings an excellent fit to the Aerohead MIPS, with one-handed adjustability.

The Giro Vanquish is much more than a variation on the original Air Attack Shield. The Vanquish is an entirely new design, using -among other things- a clever stepped outer shell profile that Giro calls "TransformAir". This shape convinces the air that the helmet is much longer than it actually is, producing impressively low aerodynamic drag similar to a long-tail TT helmet. The interior of the Vanquish still features deep, uninterrupted Wind Tunnel channels that keep the wearer cool, while a MIPS (Multidirectional Impact Protection System) liner allows the helmet to better absorb the energy of an oblique impact. The MIPS liner is integrated into the RocLoc Air fit system, reducing weight and bulk while preventing overheating. The 4-piece HardBody exterior shell and dual-density Progressive Layering construction keeps the crashworthiness of the Vanquish up to standards without adding extra weight. Over 50 different test fixtures at Giro allow the engineers to refine the design and ensure each and every Vanquish MIPS helmet will perform to their very high expectations. They even use an on-site wind tunnel to ensure excellent cooling performance.

The Vanquish also features a magnetic Vivid Shield visor produced by Zeiss Optics for excellent optical clarity and eye protection. This shield can be removed on the fly and reattached inverted with magnets when not needed. Cool, huh? If the wearer prefers regular sunglasses, there are eyeglass grippers in the front vents for storage. The interior padding boasts an antimicrobial treatment that keeps the Vanquish fresher for longer. 3 sizes will fit a wide range of riders looking for an aero advantage, or just a quieter helmet on windy days.

The Synthe is the pinnacle of road helmet design, combining the performance gains of aero efficiency and light weight with great cooling power to enhance rider comfort and efficiency. The compact form slips through the air with ease across multiple yaw and head angles, and offers greater cooling power than the Aeon. Key features include the Roc Loc Air fit system with 2-way fit tuning and Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride. Synthe MIPS models are equipped with the Multi-Directional Impact Protection System. MIPS can provide more protection in certain impacts, and this added “under the hood” technology does not compromise fit, ventilation or style.

The Seyen MIPS combines a touch of European flair with slightly deeper coverage and high-performance features—all tucked into a very slim design. The outer shell is molded from a tough polycarbonate that's fused permanently to the EPS foam liner using our In-Mold construction process to enhance durability and ventilation without excess bulk. The fit is luxurious and secure, thanks to our highly adjustable Roc Loc 5 Air MIPS system that allows you to customize fit/feel for great stability and long-range comfort. Another benefit is integrated MIPS which can provide an added measure of protection from rotational forces in the event of an angled impact.

When you're through wearing a commuter helmet on your sleek and speedy road bike -but don't want to break the bank- the Giro Syntax MIPS will be you best choice. A lightweight and well-ventilated road helmet will do wonders for you over every mile. The Syntax MIPS offers 25 Wind Tunnel vents that channel air over your head and out the back for excellent comfort on hot days. The helmet's polycarbonate shell enhances the crashworthiness overall, requiring less overall material for a closer, more aerodynamic profile. The shell even wraps around the bottom edge of the Syntax MIPS in Giro's interlocking Hardbody architecture. A RocLoc 5 Air internal fit system is integrated into the Multidirectional Impact Protection System (or MIPS) liner, making the overall fit and comfort of the Syntax MIPS better than ever. Coolfit antimicrobial padding and a slimline chinstrap and retention buckle help you forget you're wearing a helmet in the first place! A MIPS-equipped helmet does not improve the helmet's ability to continue to function safely after a hard impact. If your helmet has been involved in an accident, and you're not sure if it has been damaged, be safe and replace it.
