The Giro Syntax MIPS Helmet is known for it's relentless performance and style. Syntax MIPS combines a touch of European flair with slightly deeper coverage and high-performance features, all tucked into a very slim design. The outer shell is molded from a tough polycarbonate that is fused permanently to the EPS foam liner using Giro's In-Mold construction process to enhance durability and ventilation without excess bulk. The fit is luxurious and secure, thanks to Giro's highly adjustable Roc Loc 5 Air MIPS system that allows you to customize fit/feel for great stability and long-range comfort. Another benefit is integrated MIPS which can provide an added measure of protection from rotational forces in the event of an angled impact.
