Description
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.
Features:
- 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
- Compatible with Roc Loc 5 LED (sold separately)

Reviews
I was riding my bike along a greenway in N Portland and was run over by an f-150. The actual wheel of the truck rolled over my head with this helmet on and it did it's job like you'd hope it would, kept my melon intact. 10/10 would recommend
This road helmet was an excellent value (even more so as I got it on sale) and it feels very similar to the top end Giro helmet that I have. I think it looks good as well - it fits relatively close to your head. MIPS, good looking, comfortable, affordable... what's not to like?
Bought this helmet to replace my Specialized helmet that was nine years old. My concerns were that it would be comfortable, well ventilated for summer months, and had the new MIPS technology. It met all those needs and find it to be a great replacement helmet at a good price.
It is rated well as a safe helmet as tested by Virginia Tech for a bike helmets.
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.
I really like this helmet. It fits and is comfortable. Compared to other Giros I've owned, it covers a bit more of my forehead but has great ventilation. The RolLoc system works great as usual. It's sleek and light. Would definitely buy this again.
I long have used Giro helmets, this one is not among my favorites. As prices of all helmets have risen it is tough finding great quality and fit, style and a price that one would like to pay. I do not like the buckle system on this as it in my view is not as good as some other models of a few years back.
Wanted a reasonably priced helmet with MIPS and High Viz in it but not completely High Viz in color. Could not have found a more perfect helmet. Comfortable, easily adjusts and not heavy. Very satisfied with this purchase.
Got the helmet to replace an old Giro that the plastic side piece broke. Wanted to try MIPS because just in case. Very happy with how it fits further down over my head even with cap underneath. Comfortable and easy to adjust with knob at back. Not overly expensive which I like. Would definitely recommend.
This helmet is heavier than my previous hemet which was a Scott Wit-R. However I soon got used to it. It was important to me to get a helmet with the MIPS system in it. So at this price I think it's the best bet.
I've always used Bell helmets in the past, but the Giro Syntax MIPS helmet is much more comfortable and easier to adjust than any of my previous helmets over my past 30+ years of road cycling. I highly recommend it.
Stylish, comfortable, MIPS and a killer price point, what is not to like? I liked it enough to get two color ways, Black and Red and Matte Black and Gray, super comfy helmet.
I have been using the Giro Syntax MIPS helmet for road riding for almost a month now and my impressions are positive. This is my first helmet from the Giro brand and I'd thought I would see what all the hype was about. Many of my riding buddies use Giro helmets (especially the higher end models) and even my dad has this helmet. The large size seems to fit perfectly to my big melon right out of the box and with no adjustments to the straps. The dial at the back of the helmet is easy to adjust on the fly and I can usually get the right fit in about 16-20 clicks. Since I have a full head of hair and usually wear a cycling cap or headband, the airflow seems on par with my previous Bell Stratus and LG Quartz helmets, though, I personally don't think the helmet lacks any airflow - your experience may vary. I got the red and black color to compliment that of my bike and shoes. It looks much better in person but the picture online is pretty close. One thing I find lacking due to the vent placement is a place to securely put sunglasses when not wearing. Despite that small detail, the helmet is comfortable enough to wear all day even with sunglasses on and AfterShokz headphones. It's really light and sometimes I don't even notice I have it on. The deeper coverage of the helmet allows it to sit more forward on my head, and riders I know wished their Specialized and Bell helmets had this same feature. The helmet seems pretty durable over the long-term and I trust that it will keep me from getting seriously injured in the event of another crash. 2020 has not been too kind as I have already had three this year.
Overall, I would buy this helmet again and would recommend it to anyone. What you get when compared to other helmets is simply a no-brainer at this price point. I did quite a bit of research and definitely read my share of reviews before buying. For the sake of your noggin and making informed decisions, I recommend you do the same.
I was looking for a new helmet and was driving myself crazy with all of the different choices out there. I read various reviews of the 2 or 3 that I had narrowed it down to and still couldn't make up my mind. I then noticed the Giro Syntax MIPS. I don't know how I had missed it before but I'm glad that I found it. The reviews I read on it were better than the ones for the helmets I was considering. On top of that, there was a great sale price available, so I took the plunge. I have been using it for almost 2 months now and I am very pleased with it. It is quite light weight. I hardly know it's there. It fits well and has a University of Virginia 5-star rating. Who could ask for more? For anyone who might be wondering about size, the size chart seems to be correct. My head measures about 58.5 cm so I ordered a medium and it is perfect.
