<p>Slotting in just above the updated Synthe MIPS II, the all-new Giro Helios Spherical Helmet serves as Giro’s premium adventure helmet. With Giro calling out the Helio’s primary safety feature in its appellation, it’s clear that the focus of cycling helmet evolution continues to be rider comfort and protection. For those unfamiliar, spherical technology is a brain-child of Bell + Giro Dome in partnership with MIPS. The unique ball-and-socket design, thankfully, is easy to conceptualize. The Helios Spherical is a Progressive Layering system with an inner and an outer liner that can rotate around each other in an impact. All you have to do to visualize this is make a fist, and then rotate your other hand over the fist. The result is a more comprehensive platform for rider protection.</p>

<p>Giro doesn’t stop there, however, as the Helios Spherical is aimed straight at the adventure cyclist with 15 Wind Tunnel vents and channels that run deeply in the underside of the helmet to keep heads cool during epic, route-free riding.</p>

<p>Whether we're chasing the World Tour or just competing in our local crit series, the Giro Aries Spherical Helmet keeps our dome protected thanks to a new MIPS Spherical design. Built to be lighter and lower profile than the Aether, the Aries delivers best-in-class protection with insane amounts of airflow so that we're not overheating during big climbs and finish line sprints.</p>

<p>Kask turned the dial up with their Protone Icon Helmet. Enhancing upon its base version, the Icon features an even sleeker shape to maximize ventilation and aerodynamics so we may move at greater speeds with greater comfort. And while comfort is of high importance, protection is even more so. We can trust the rotational tests of Kask for that.</p>

<p>The KASK Elemento Helmet keeps us riding in style with no sacrifice in speed, comfort, and protection. The combination of KASK’s Fluid Carbon 12 and Multipod technologies absorb and distribute the forces felt upon impact evenly across the helmet to help keep us safe in the event of a crash, while the Hyvent ventilation system maximizes airflow to keep us cool and comfortable on even the hottest rides.</p>
