At the heart of the Helios' exceptional design and performance is Spherical technology, which uses the unique ball-joint design of MIPS, the market leader in head and brain protection. Spherical technology allows the outer helmet inner shell to rotate around the inner shell in the event of a fall. At the same time, the progressive layer system of the two shells provides comprehensive protection and performance. In addition to improved head protection, the Helios' 15 vents provide optimal ventilation, which is further enhanced by our patented Roc Loc 5 Air Fit system. The antimicrobial Ionic+ pads not only have the highest antimicrobial sweat-absorption properties, but also ensure the highest level of comfort. The Helios is perfect for all road and gravel adventures.
