Lest we forget about the importance of aerodynamics, Giro provided data that showed the Aether was 2.4% more aerodynamically efficient than the Synthe MIPS. Giro claims the Aether is two-degrees cooler than the Synthe MIPS. The AURA bridge not only prevents large objects from passing through the vents, it also provides additional structural integrity and allows air to flow through. To solve this, Giro created a translucent shatterproof AURA (Aerodynamic Ultimate Reinforcing Arch) designed to shield the vents. The vents ended up being wide enough that large objects were able to pass through during initial testing, which created a safety issue. The Aether’s design focuses on ventilation and thermodynamics - vents run throughout the helmet to keep you cool. Consider them siblings, but with unique personalities.Īether’s tough outer shell is constructed from six different polycarbonate pieces fused together. That may be why at first glance Aether looks a whole lot like the Synthe. That creative process started three years ago, not long after the launch of the Synthe. The complexity of MIPS Spherical forced Giro to get creative while designing Aether’s outer shell. (Bell uses a similar two-piece EPS design on its Zephyr helmet, now known as the Z20.) The nanobead foam gave Giro a bit more room to work with, allowing them to add foam into the nooks and crannies of the helmet, thus adding more protection. Spherical is essentially two helmets rolled into one. Giro used a nanobead version of EPS foam to create the two-part MIPS Spherical interior. Giro explained that designing a ski helmet with the new MIPS Spherical was easier than figuring out a cycling helmet, which has a more limited space capacity, as well as and the need for good ventilation MIPS Spherical first debuted in Giro’s Avance ski helmet, so the technology isn’t brand new, and it is well tested. However, with the addition of MIPS Spherical, the relationship between the Swedish-based company and Giro has evolved. Shapleigh explained that the two companies work together, but MIPS also tries to step back and have little influence in how Giro designs its helmets. Greg Shapleigh worked for Giro for over 25 years before he left to join the MIPS marking and sales team in 2017. Since then, many of Giro’s helmets in its road line come in two options - one with MIPS and one without. Giro first debuted a MIPS equipped helmet in the Fall of 2014.
A MIPS system adds 10-15 millimeters of movement across all three planes (X, Y, Z), so the rider’s head stays stable during oblique impacts while the helmet rotates. As is the case with most MIPS product options, the inner shell technology integrates smoothly into a helmet. MIPS’s inner shell technology reduces rotational forces against the brain and has arguably become the most notable safety advancements in helmets within the last decade. In essence, the MIPS Spherical eliminates the need for the added slip-liner. It is a two-part dual density foam that redirects energy during angled impacts. MIPS Spherical is different in that the technology isn’t an additional element to the helmet it is the helmet. This is MIPS’s entry-level protection system. You’ll probably know MIPS as the yellow plastic slip liner that helps to keep the head still during oblique impacts while the helmet rotates.
Giro’s four-year partnership with MIPS Technologies (Multi-directional Impact Protection System) enters a new phase by integrating MIPS Spherical into the helmet. However, it’s what lies underneath the outer shell that really sets the two apart. And while both helmets look sleek and fast, Aether is 20 grams lighter than Synthe (250g for a medium), and offers heaps of ventilation. The Aether shares the aesthetics of Giro’s Synthe MIPS.
