Product description of Giro Syntax helmet

Description summary

Experience the Giro Syntax MIPS helmet: a fusion of European style and advanced protection for road and gravel cyclists. Its slim design boasts deeper coverage and In-Mold construction for durability and ventilation. The customizable Roc Loc 5 Air MIPS system ensures a secure, comfortable fit. With 25 Wind Tunnel vents and integrated MIPS technology, enjoy superior cooling and rotational impact protection for exhilarating rides. Lightweight, robust, and stylish

Giro Syntax MIPS Helmet | Advanced Road & Gravel Cycling Protection

Relentless Performance and Style

The Syntax 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´s fused permanently to the EPS foam liner using our In-Mold construction process to enhance durability and ventilation without excess bulk. The fit is luxurious and secure, thanks to our highly adjustable Roc Loc 5 Air MIPS system that allows you to customize fit/feel for great stability and long-range comfort.

Engineered for the Modern Rider

Experience the perfect fusion of safety, comfort, and aesthetics with the Giro Syntax MIPS helmet. Designed for the discerning adult cyclist who demands performance on every surface, this helmet is your ideal companion for everything from spirited road cycling to adventurous gravel cycling expeditions. Its sleek profile and deeper rear coverage not only provide a confident, secure feel but also deliver a sophisticated look that stands out from the pack. The advanced In-Mold construction is the secret to its lightweight yet robust structure, ensuring it can withstand the rigors of daily use while remaining barely noticeable on your head.

Unrivaled Comfort and Cooling

Say goodbye to uncomfortable, sweaty rides. The Giro Syntax is engineered for superior ventilation. A network of 25 Wind Tunnel vents works in concert with internal channeling, actively pulling cool, fresh air over your head and pushing hot, stale air out. This powerful cooling system keeps you comfortable and focused, even during the most strenuous climbs or on hot summer days. The comfort is further enhanced by the revolutionary Roc Loc 5 Air MIPS fit system. This industry-leading design allows you to easily dial in both fit tension and vertical position with single-handed micro-adjustments. It creates a customized, cradle-like fit that feels made just for you, ensuring exceptional stability and eliminating pressure points for all-day wearability.

Integrated Protection Technology

At the heart of the Syntax´s protective capabilities is the integrated MIPS® (Multi-Directional Impact Protection System). This low-friction layer is designed to redirect rotational forces away from the brain during certain angled impacts, providing an additional measure of protection in a wide range of real-world cycling incidents. This advanced safety feature is seamlessly integrated with the helmet´s fit system, ensuring it does not compromise comfort, ventilation, or style. Ride with the peace of mind that comes from wearing a helmet built with cutting-edge protection technology.

Good helmet, lightweight, anatomical and good quality, very fast shipping. However, it does not have the MIPS system as advertised, so if you are looking for this system this is not your case .......... the description is very misleading.
