The heart of the Giro 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 comprehensive 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.Key FeaturesSpherical Technology™MIPS® brain protection system Progressive Layering Nanobead EPSIonic+™ anti-microbial paddingReflective decalsConstructionIndependent, In-Mold liners with spherical ball-and-socket design.Full lower Hardbody coverage.Fit SystemRoc Loc® 5 AirVentilation15 Wind Tunnel™ vents and deep internal channeling
