As close to luxurious as a helmet can get thanks to Giro's highly adjustable Roc Loc™ 5 Air Mips system. Using a patented design that suspends the helmet just slightly off the top of the skull, the air version of Giro's signature Roc Loc allows cool airflow to pass directly over your head. The Syntax allows you to customize fit and feel for great stability and long-range comfort while providing an added measure of protection from rotational forces in the event of an angled impact. It also has slightly deeper coverage and a slim design to keep you comfortable whether you're riding on city roads or mountain trails.
