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

Excellent Helmet
by Anonymous

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.

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.

Picture not representative

The inner frame of the white helmet is bright white, so you see bright white stripes on your head through the holes. Obviously not the most important feature, but it looks truly bizarre against any hair that isn't white.

Good helmet, ventialtion a bit lacking
by OaklandMark
Cycling Enthusiast

I'm a road rider, and needed to replace my aging Giro. Not wanting to spend a fortune, I picked this one. As expected, the fit was perfect, as I know from experience that Giro helmets fit me extremely well. My head measures right in the middle of M range, and I can pretty much wear the thing straight out of the box.

My only quibble was that after a couple of rides I felt the ventilation was really lacking. If you're riding for a few hours in hot weather, you really don't want your head to roast any more than necessary, and mine was.

I ended up giving the helmet to my son, to his delight, and ordering the Aether, on sale. It also fit perfectly, AND had good ventilation.

If you're just tooling around, the Syntax is a great helmet. But if you're out for a ride of a few hours, you might want to look at something with better vents.

Unbeatable MIPS protection at the price!
by cmurder

Lightweight, good airflow, and a low profile. Pretty much a triple threat. MIPS protection which should be mandatory at this point. If you haven't looked into MIPS, I'll sum it all up for you do yourself a favor and throw out your old helmet and buy one with MIPS. One of the best helmets on the market, especially for the price.

Good fit with important safety features.
by Anonymous

I've worn several Giro helmets over the years, and found them easy to adjust and comfortable to wear. Safety is a concern, and the MIPS feature is an important addition for me. Fortunately, I haven't had to test whether the helmet will protect me from serious head injuries, but the reputation of Giro for a quality product does make me comfortable trusting that the helmet will protect me.
