Absolute waste of hard earned money . Bad quality , built like a cheap Chinese brand . It’s a shame for a brand like giro often featured on gcn.
Giro design, and high-performance innovation for core road cyclists, gravel enthusiasts, and adventure riders. The heart of Helios's 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 comprehensive protection and performance. In addition to advanced head 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, antimicrobial XT2 padding for exceptional sweat absorption. It's the ideal match for your road and gravel adventures.
MIPS Spherical Technology - proprietary MIPS Spherical technology is embedded between the layers of EPS foam – instead of against the rider’s head – giving riders the benefits of MIPS without any obstruction to comfort or cooling power
