Giro Helios Spherical Road Helmet - Matt Black Xing - 2022

Giro Helios Spherical Road Helmet - Matt Black Xing - 2022 Slotting in just above the updated Synthe MIPS II, the all-new Giro Helios Spherical Helmet serves as Giros premium adventure helmet. With Giro calling out the Helios primary safety feature in its appellation, its 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. Giro doesnt 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. MIPS Spherical Technology - proprietary MIPS Spherical technology is embedded between the layers of EPS foam instead of against the riders head giving riders the benefits of MIPS without any obstruction to comfort or cooling power Construction: Independent, In-Mold liners with spherical ball-and-socket design.
