The heart of the Helios’s extraordinary design and performance is Spherical Technology, which utilizes a ball-and-socket design powered by MIPS®, the market-leading protection system that can help to reduce rotational forces. Spherical Technology allows the helmet’s outer liner to rotate around the inner liner during a crash, and also allows Progressive Layering of the inner and outer liners to provide more comprehensive protection and performance. In addition to advanced protection, the Helios’s 15 Wind Tunnel vents provide exceptional cooling power that’s enhanced by our patented Roc Loc 5 Air fit system and plush, XT2 padding for exceptional sweat absorption. It’s the ideal match for your road and gravel adventures.
