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 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.

Giro pioneered the aerodynamic helmet category with the original Advantage in 1985, and now they are redefining it with the Aerohead Ultimate MIPS—their fastest time trial helmet ever. They leveraged every resource available to create a helmet that tops the podium in speed, weight, style and comfort. The shell is constructed with TeXtreme carbon fiber, an advanced material that is lighter and stronger than other carbon composites. The wrap-around eye shield offers an unblocked field of view with a huge aerodynamic benefit and the shield is made by ZEISS Optics for unrivaled clarity. A magnetic anchor attachment keeps the shield secure, yet easy to remove, and it can be stored in the “flipped up” position. Other stand-out features include a Roc Loc Air fit system and a hydrophilic, anti-microbial brow pad that can absorb up to ten times the amount of sweat as standard urethane padding. Additionally, this helmet is quipped with the MIPS system to redirect impact energy, providing more protection in certain impacts.

The Aether MIPS combines airy, open design with a revolution in rotational energy management to advance head protection for cyclists. Inside the Aether, a dual-density EPS foam liner helps to manage a wide range of impact energies, while also boasting deep internal channeling to provide cooling airflow. Giro's proprietary MIPS Spherical technology is integrated between the layers of EPS foam – instead of against the rider’s head – giving riders the benefits of MIPS without any obstruction to comfort or cooling power. Outside, a sleek 6-piece shell forms a stunning silhouette around the massive vents, which get added structural reinforcement via a shatter-resistant AURA reinforcing arch. The final touch is Giro's Roc Loc 5+ Air fit system, featuring 3-way fit tuning, that allows easy adjustment in seconds for the ultimate in comfort.

When it's time to hit the road, the Agilis MIPS offers a sporty, sleek style with comfortable features you can count on, including 32 wind tunnel vents, Coolfit anti-microbial padding, and integrated MIPS technology. The fit on the Agilis MIPS is comfortable and secure thanks to our adjustable Roc Loc 5.5 MIPS system that combines fit and positioning adjustments while integrating with MIPS technology for an added measure of protection in the event of an angled impact. The outer Hardbody shell extends to the inside of the helmet, and is molded from a tough polycarbonate thats fused permanently to the EPS foam liner using our In-Mold process to enhance durability and ventilation without excess bulk. - 32 Wind tunnel vents with internal channeling - Full-wrap in-mold polycarbonate shell with EPS liner - Coolfit anti-microbial padding - Featherweight webbing with Slimline buckle - Roc Loc 5.5 MIPS fit system

A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology™, our ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore™ brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc® 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style. - AURA II REINFORCING ARCH — The shatter-resistant and translucent Aura II Reinforcing Arch runs throughout the helmet, bolstering structural integrity and allowing massive vents for cooling - VIRGINIA TECH #1 RANKING — Researchers at independent testing facility Virginia Tech gave Aries Spherical their best score event in their rankings of which helmets best reduce the risk of injury. All Giro helmets with Spherical Technology have received their top level of 5 stars. - DRYCORE™ — The DryCore™  sweat management system utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes. - SPHERICAL TECHNOLOGY — Spherical Technology's Ball-and-Socket design, powered by Mips®, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin. - MIPS® BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts. - 21 WIND TUNNEL VENTS — Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust cool, fresh air over and around the rider's head while forcing heat and stale air out. - DEEP INTERNAL CHANNELING — Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power. - PROGRESSIVE LAYERING™ — Giro helmets with Progressive Layering™ use two different density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management. - EYEWEAR DOCKING PORTS — Integrated eyewear docking ports with rubber grippers help to secure sunglasses. HIGHLIGHTS - AURA II reinforcement arch - Ionic+™ anti-microbial padding - DryCore™ sweat management system - Eyewear docking ports Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older

LIGHTER, COOLER, SLEEKER, PLUS ALL THE ADDED PROTECTION OF SPHERICAL TECHNOLOGY POWERED BY MIPS® AND OUR NEW DRYCORE™ SWEAT MANAGEMENT SYSTEM: THE ARIES SPHERICAL IS LIKE NOTHING BEFORE. STRUCTURAL INTEGRITY The proprietary AURA II Reinforcement Arch makes everything possible. These shatter-resistant, translucent twin bridges run throughout the helmet, providing structural integrity without adding unnecessary weight. Aries’ ultra-low weight (~5% lighter than Aether), impressive cooling power and sleek, compact shape would not be possible without AURA II. SPHERICAL TECHNOLOGY This unique ball-and-socket design, powered by Mips®, helps redirect impact forces. Spherical Technology also boasts more comfort, improved airflow, and Progressive Layering (which mates two densities of EPS foam to address a wide range of impact energy). The results are clear: independent authority Virginia Tech has rated Aries #1 in reducing the risk of injury. It’s the best performing helmet they’ve tested so far – even out-performing much bigger, bulkier helmets at reducing risk. COOL COMFORT Deep internal channels connect with Aries’ massive front and rear vents. This system provides a path for cool air to flow over the rider’s scalp and exit the rear, taking excess heat with it. Aries outperforms our previous cooling benchmark, the Aether, with a 2.3% improvement in cooling efficiency. STREAMLINED SPEED When it comes to going fast, smaller truly is better. To craft Aries, we focused on reducing the frontal surface area to eliminate more drag. Add in tiny details like chamfered edges on the AURA II, and meticulously engineered internal channeling that actually speeds up the air as it exits the helmet, and Aries emerges as the climbing helmet that doesn’t sacrifice speed, reducing aerodynamic drag by 4% over Aether Spherical. Aries also debuts our revolutionary DryCore™ sweat management system. A soft, silicone bead is hidden within the plush brow pad that redirects sweat away from the forehead and to the temples, where it can evaporate more easily.
