The Giro Helios Bike Helmet has the newest technology and is sure to protect cyclists like you who want essential coverage and style. This helmet has an extraordinary design and performance thanks to its 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. The Helios' Spherical Technology allows the helmet's outer Liner to rotate around the inner Liner during a crash, as well as allows the Progressive Layering of the inner and outer Liners to provide more comprehensive protection and performance. In addition to advanced head protection, the Helios' 15 Wind Tunnel vents provide exceptional cooling power that's enhanced by Giro's patented Roc Loc® 5 Air fit system and plush, antimicrobial XT2 padding for exceptional sweat absorption. The Giro Helios Road Helmet is the ideal match for your road and gravel adventures.
