The centerpiece of the exceptional design and performance of the Helios is the Spherical technology, which utilizes MIPS's unique spherical joint design, the leader in head and brain protection. The Spherical technology allows the outer shell of the helmet to rotate around the inner shell during a fall. At the same time, the progressive layering system of the two shells provides comprehensive protection and performance. In addition to enhanced head protection, the Helios features 15 ventilation openings for optimal airflow, further improved by a patented Roc Loc 5 Air Fit system. The antimicrobial Ionic+ padding not only offers superior antimicrobial sweat absorption properties but also ensures maximum comfort. The Helios is perfectly suited for all road and gravel adventures. Special features: Reflector(s). Intended use: Road bike / Cyclocross. Certification: EN 1078. Weight: 270 g. Visor: None.
