At the heart of the Helios' exceptional design and performance is Spherical technology, which uses the unique ball-and-socket design from MIPS, the leader in head and brain protection. Spherical technology allows the outer helmet liner to rotate around the inner liner in the event of a fall. At the same time, the progressive layering system of the two shells provides full-coverage protection and performance. In addition to enhanced 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+ padding not only has the highest antimicrobial sweat-absorbing properties, but also ensures maximum comfort. The Helios is perfect for all road and gravel adventures. - Intended use: road bike / cyclocross - Test mark: EN 1078 - Weight: 270 g - Visor / peak: without - Details: - Weight specification size M - Pads: anti-bacterial pads - Material: In-Mold polycarbonate shell with progressive Nanobead EPS inner shell, fully covered Hardbody EPS shells - Adjustment system: Roc Loc 5 Air - Helmet construction: In-Mold + MIPS - Function: with strap adjustment system - Features: Reflector(s) Ventilation openings - Number: 15.
