The centerpiece of the exceptional design and performance of the Helios is the Spherical Technology, which utilizes MIPS's unique spherical joint design, the market leader in head and brain protection. 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 15 ventilation openings of the Helios ensure optimal airflow, further improved by our patented Roc Loc 5 Air Fit system. The antimicrobial Ionic+ padding not only offers superior antimicrobial sweat absorption properties but also ensures maximum comfort while wearing.
