Long-range comfort meets relentless performance and style with the Syntax™. It has slightly deeper coverage and a slim design to keep you comfortable whether you're riding on city roads or mountain trails.
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.
- HARDSHELL WITH IN-MOLD HARDBODY™ LOWER WRAP — The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.
- WIND TUNNEL VENTILATION — Giro helmets are developed utilizing our proprietary Wind Tunnel™ ventilation system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider's head while forcing heat and stale air out. It's the most effective cooling system available, and a difference you can feel every time you ride.
- IONIC+® PADDING — Pure Silver is the secret ingredient that gives IONIC+® the power to provide natural, permanent odor protection to keep your helmet feeling fresh.

Bike Helmet Size Guide
How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
