Helmets

An updated classic. Already one of our most popular trail helmets of all time, the Montaro MIPS II now benefits from the Roc Loc 5 Air MIPS System. This sleek design integrates 2-way fit and stability adjustment with the MIPS brain protection system for an added measure of protection from rotational forces without excess plastic against your skin. The helmet's compact shape offers deep coverage and an in-mold hardbody shell for enhanced durability without excess weight. In addition to advanced brain protection, the Montaro II is outfitted with IONIC+ padding with permanent antimicrobial performance plus 16 vents with internal channeling to keep you cool and comfortable. We also built in all of the features you need for great fit with goggles, including strap grippers on the back of the helmet and our patented P.O.V. Plus visor that allows you to lift the visor and place your goggles on the front of the helmet when your run is done. A clever breakaway interface for your favorite light or camera is included, too.

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.

The Eclipse Spherical is both the fastest road helmet and the coolest aero road helmet Giro has ever created, bringing our best technologies together in a light, compact form that's ideal for road and gravel racing. The sleek outer shell actively streamlines airflow to reduce drag across multiple wind angles, while 14 Wind Tunnel vents pull air through the helmet to provide incredible cooling power that rivals our most aggressively vented road helmets. Inside, the ball-and-socket design of Spherical Technology is powered by the MIPS brain protection system, which allows the helmet's outer EPS foam liner to rotate around the inner foam liner during a crash to help redirect impact forces away from the brain. Progressive Layering of both the inner and outer liners help to offer more comprehensive protection, too. The patented Roc Loc 5 Air system enhances stability and fit, and plush antimicrobial Ionic+ padding helps absorb sweat and moisture while providing durable antimicrobial performance.

Giro's Helios MIPS helmet represents the cutting edge in high-performance innovation for road cyclists, competitive riders and gravel enthusiasts. The heart of the Helios's extraordinary design and performance is Spherical Technology, which utilizes a ball-and-socket design powered by MIPS. This design is the next technological step in helping to reduce the rotational forces caused by oblique impacts. This same design is used in the construction of elite motorsports helmets. Spherical Technology allows the helmet's outer liner to rotate around the inner liner during a crash, and also allows Progressive Layering of the inner and outer liners to provide more comprehensive protection. In addition to advanced head protection, the Helios's 15 Wind Tunnel vents provide exceptional cooling power that's enhanced by our patented Roc Loc 5 Air fit system and plush, antimicrobial XT2 padding for exceptional sweat absorption. It's the ideal match for your road and gravel adventures.

Among the Manifest's extraordinary features is Spherical Technology, which utilizes a ball-and-socket design powered by MIPS, the market-leading brain protection system that helps to reduce rotational forces. Spherical Technology allows the outer liner to rotate around the inner liner during a crash and also eliminates contact with a hard-plastic slip-plane. In addition to leading head protection, the Manifest offers wide-open airflow thanks to the AURA reinforcing arch, which bolsters structural integrity while allowing air to flow into the massive Wind Tunnel vents. You'll also get a comfortable, secure fit with the easy fit and positioning adjustments built in to the Roc Loc Trail Air fit system and plush, antimicrobial XT2 padding for exceptional sweat absorption. - 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. - Dual-density foam liners designed to address high- and low-speed impacts for more comprehensive energy management. - Structural integrity is bolstered by the shatter-resistant and translucent AURA reinforcing arch that runs throughout the helmet. - Integrated eyewear grippers help secure sunglasses. - 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. - This visor features an adjustment mechanism that lets you move the visor up and down in indexed steps. These steps include three riding positions plus a high position for goggle storage above your brow. The design allows you to easily adjust your visor with one hand while riding. - Pure silver is the secret ingredient that gives XT2 the power to provide natural, permanent anti-odor protection to keep your helmet feeling and smelling fresh. - The integrated rubber goggle gripper on the back of the helmet helps to ensure that goggles stay in place even when you're getting rowdy on the trail. - The Roc Loc Trail Air Fit System offers micro-adjustable fit adjustment, enhanced ventilation, and durable design that resists abrasion, scratches, and UV rays.

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. LIKE NOTHING 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.

Bicycle helmets have been made the same way for over 30 years: Expanded polystyrene (EPS) with a polyester shell bonded onto the outside. New MIPS liners are a great innovation that addresses oblique impacts better, but the bicycle helmet has been largely unchanged.

Until now...

The WaveCel helmet design from Bontrager uses a completely different material called cellular copolymer. When used in conjunction with EPS and a polyester shell, this new material provides a much better management of real-world impacts that might cause a concussion. Even oblique impacts are absorbed much more effectively by the WaveCel honeycomb material by shearing progressively in the event of a hard impact. WaveCel material was developed as a helmet material from the beginning in Portland, Oregon at Legacy Biomechanics Laboatory. Using EPS and a polyester shell for the helmet's exterior allowed the designers at Trek and Bontrager to build the outside of the XXX helmet with familiar materials. Improved airflow ventilation and innovative external styling was always part of the plan when starting with a fresh helmet design.

The Bontrager XXX helmet is a no-compromise aero road helmet with sleek styling and excellent ventilation. The Trek-Segafredo pro cycling team has been putting the new helmet through the wringer of the pro racing season, trusting it to protect them while racing in conditions fair and foul. A Boa closure at the rear of the helmet allows one-hand adjustment while keeping the interior fit system light. The interior also features AgIon padding that eliminates odors naturally. There's even a second interior pad set with a NoSweat silicone channel to help keep sweat out of the rider's eyes. 9 large exterior vents allow smooth airflow when riding in hot and humid conditions.

The WaveCel material does not allow the Bontrager XXX helmet to sustain repeated hard impacts. If your helmet is damaged in a crash, replace it. Bontrager's Crash Replacement Guarantee provides a free helmet replacement if involved in a crash within the first year of ownership
