The Giro Helios Spherical Helmet combines Giro's ever popular Synthe MIPS II helmet with Spherical protection for multi-discipline riders. Featuring the all-new Spherical protection system powered by MIPS which offers multi-layered impact protection, the Helios liner rotates around the shell. When combined with Hardbody Coverage for the brain and top of your spine, adventurous riders are offered the most comprehensive head protection currently available. Of course, without Giro's class-leading, plush Roc Loc 5 Air fit system, the Helios Helmet wouldn't be able to offer such a secure, yet comfortable fit. While the Helios offers incredible cooling efficicency thanks to 15 wind tunnel inspired vents and internal channelling that forces air through the helmet to ensure you're always comfortable regardless of the weather, event or terrain! Whether you ride on the road, gravel or even cross-country, the Giro Helios Spherical Helmet will keep you protected no matter what lies ahead!
