Giro Helios Spherical Helmet

The heart of the Helios&';s extraordinary design and performance is Spherical Technology, which utilizes a ball-and-socket design powered by MipsA(R), 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.
