The perfect choice for skiers and snowboarders, the new Giro Ratio helmet uses MIPS technology, an in-form fit system and a hard shell construction to improve over-all fit and maximise impact protection. Alongside these improvements, the Giro Ratio also combines a customisable ventilation system and stack venting to manage the internal microclimate and eliminate fogging. The Ratio is compatible with all Giro goggles and features an audio compatible port to help you get in the zone when shredding some powder.
