Giro Helios Spherical Bike Helmet

The heart of the Helios’ extraordinary design and performance is Spherical Technology™, which utilizes a ball-and-socket design powered by Mips®, the market-leading brain 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 compre- hensive protection and performance. In addition to advanced head protection, the Helios’ 15 Wind Tunnel vents provide exceptional cooling power that’s enhanced by our patented Roc Loc® 5 Air fit system and plush, antimicrobial Ionic+™ padding for exceptional sweat absorption. It’s the ideal match for your road and gravel adventures.
