Why We Like The Aether MIPS Helmet

The Aether MIPS is Giro's range-topping road helmet, offering a professional-level fit and finish along with superb ventilation and advanced safety features. The standout feature is the MIPS Spherical protection system—an updated version of MIPS that's exclusive to Giro and Bell. Spherical MIPS places the slip-plane technology in between the layers of EPS foam, rather than against the rider's head. This gives us the protective benefits of MIPS without any sacrifice to comfort or cooling power.


  • A no-compromise road helmet that's big on safety and comfort
  • In-Mold construction fuses the laser-cut shell to the EPS foam
  • Roc Loc 5 Plus offers quick, customized adjustments
