Giro Syntax MIPS® Helmet

The Syntax MIPS® Helmet combines a touch of European flair with slightly deeper coverage and high-performance features—all contained within a very slim design. The outer shell is molded from a tough polycarbonate that's fused permanently to the EPS foam liner using an In-Mold Hardbody™ construction process to enhance durability and ventilation without excess bulk.


  • Comfortable and secure fit, thanks to the highly-adjustable Roc Loc® 5 Air MIPS® system
  • Customizable feel for great stability and long-range comfort
  • Wind Tunnel Ventilation with internal channeling to thrust cool air over and around the rider's head while forcing heat and stale air out
  • Integrated MIPS® (Multi-Directional Impact Protection System) which can provide an added measure of protection from rotational forces in the event of an angled impact

Great helmet

Im a big fan of the styling of Giros helmets, and this mode in particular fits well, is lightweight, and looks good. My only issue is that I always seem to break the flimsy plastic parts of the Roc Loc system within a couple months.

Excellent Helmet

Not a budget helmet, not an expensive helmet, but a great helmet! This thing has really good ventilation and is super light. I had a hard time finding a good helmet for my noggin due to a large ridge on the back of my skull. Most helmets weren't able to go down far enough below the ridge, but THIS helmet fit so well. Would recommend.
