Advanced Protection The Aether Helmet (MIPS) is designed with a host of features to provide you with the ultimate combination of protection, fit and ventilation. First, let's look at protection. The Aether is engineered with a dual-density EPS foam liner that makes it capable of absorbing a wide range of impact energies. Meanwhile, the 6-piece outer is reinforced with a shatter-resistant AURA reinforcing arch giving a boost to structural integrity in the event of an impact. Protection is then bolstered by Giro's proprietary MIPS Spherical technology - this design sees the MIPs technology deployed between the layers of EPS foam rather than immediately next to the head which enables Giro to maintain incredible cooling airflow and comfort. What is MIPS? The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head. Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head. Shop All MIPS Helmets Click Here Cool and Comfortable So that's the protection, now let's look at ventilation and fit. As mentioned, the unique MIPS design has allowed Giro to maintain excellent airflow inside the helmets. This is fully taken advantage of with 11 Wind Tunnel vents over the helmet, all leading to internal channelling that forces air across the scalp. With the extensive venting, you'll enjoy a cool head even in the warmest conditions. The large and airy vents are made possible thanks to the support of the AURA reinforcing arch, maintaining structural integrity while giving scope to increase vent size. Roc-Loc® 5 fit system Now let's turn to the fit and the Roc-Loc® 5 fit system. This is the industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.
Giro Aether Helmet (MIPS)Featuring among the World's most effective protection, the MIPS-assisted Aether Helmet from Giro is a revolution for the road. MIPS works hard to keep your head still in the event of a collision, working alongside a dual-density EPS foam liner that absorbs energy perfectly.On the outside of the helmet, the reinforced, shatter-resistant AURA arch holds the helmet together for full structural integrity in the event of a crash. Meanwhile, extraordinary levels of comfort are provided by a construction focused on breathability, via 11 Wind Tunnel vents that keep you cool, and wicks sweat away from your head quickly. Finally, the CoolFit anti-microbial finish keeps you feeling fresh over longer distances, and eyeglass grippers add a lovely extra layer of practicality, too.Roc-Loc® 5 fit systemHolding it all together, alongside the MIPS system outlined below, is the industry-leading Roc-Loc® 5 fit system. Combining comfort and stability for your head without adding any extra weight to your ride, it keeps close to your skull for unbeatable security, with an easily adjustable fit that can be dialled quickly and easily using only one hand.MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents.

Aerodynamic performance, safety and ventilation do not need to come at the expense of each other. By using our whole-helmet approach to development, we have been able to deliver unparalleled levels of aerodynamic performance, safety and ventilation without compromise in the Ventral MIPS. Taking inspiration from the Venturi effect, the helmet's airflow zones allow the helmet to pass through the air with greater efficiency, making it faster. Residual air traveling around the helmet is managed by the 22° aero trailing edge, the perfect angle for minimizing turbulence, further improving aerodynamic performance. By leading air through rather than around the helmet, its wake is minimized, while its ventilation and cooling properties are enhanced. Other features of our whole-helmet approach include a fully wrapped unibody shell with an EPS liner for the ideal balance between weight and protection. Now including MIPS for enhanced rotational impact protection, the helmet also features a lightweight adjustment system spanning the whole head for a comfortable and secure fit.

For more than thirty years MET has been making helmets for the very best in the sport of cycling. They ve learned, refined, and developed their products, getting faster, lighter and more comfortable with every generation. Enhanced for use in the peloton, the MET Trenta Mips is a performance road helmet engineered to maximise ventilation and save you energy with every pedal stroke.In-mould polycarbonate shell with EPS linerMIPS C2 rotational management system engineered to add protection in case of certain impactsExceptionally comfortable and secure on the head thanks to refined internal shapeMET Safe-T Orbital Fit System360° Head belt, vertical and occipital adjustments leave you with an individual fitAir Lite straps with adjustable divider to maximise aerodynamic and comfort19 Vents, Internal engineered air channelling system to improve ventilation and comfortSunglasses ports to securely dock sunglasses when climbing or restingTube-shaped tail to improve aerodynamicsRear deflector to enable a constant airflow in riding positionLimited head contact surface to maximise the ventilationReflective rear decals to enhance visibility in low-light conditionsS , 52/56cm , 240gM, 56/58cm , 250gL , 58/61cm , 285gFeaturing the MIPS-C2 rotational management system, the MET Trenta Mips is able to slide relative to the head in the case of a crash, redirecting damaging rotationalmotion. MIPS is a brain protection system engineered to add protection to the standard construction of helmets in case of certain impacts. The MIPS Brain ProtectionSystem (BPS) is attached inside the helmet, between the comfort padding and the EPS.Originally developed by NACA, a precursor to NASA, the position of this inlet at the front of the helmet has a cooling effect. Harnessing the power of the Venturi effect, the vent pushes out the warm air within the helmet through specially positioned exhausts. This ensures constant airflow through the helmet, without catching the wind and creating drag, achieving the maximum level of comfort during the longest rides on the road or on your gravel bike.Enhanced for use in the peloton, the MET Trenta s tube-shaped tail and internal air channelling ensure it performs best when riding in a group, offering up to 7% reduction in drag vs a traditional road helmet. It has a lower profile at the rear, which works in synergy with the NACA front vent and the rear deflector to effectively drive airflow.
