Ultra Light. Great Protection.

The compact form of the Synthe MIPS® slips through the air with ease across multiple yaw and head angles, and offers impressive cooling power. Key features include the Roc Loc Air fit system with 2-way fit tuning and Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride. The Synthe MIPS® also has the Multi-Directional Impact Protection System, which we believe can redirect energy and provide more protection in certain impacts.

The Synthe MIPS has the most efficient aerodynamic profile of any of Giro's previous road helmets, yet it has greater cooling power than their lightest weight Aeon. In fact, it's almost as cool as a bare head over 30 minutes according to Giro's test results.

Perfect Fit + Ventilation = Giro Synthe MIPS

This uncompromising design is made possible thanks to a wind-tunnel aided design that uses integrated mesh panels to reduce drag and internal ventilation channels working in tandem with a Roc Lock® Air fit system that effectively suspends the helmet just over the skull to improve airflow.

The fit is micro-adjustable with a one-handed dial adjuster, and the X-static padding keeps it plush and fresh. Among the 19 external vents, there is also a dedicated sunglass docking port to stow sunglasses when they're not in use, and featherweight webbing with a Slimline buckle help keep the weight of this helmet down to a claimed 270 g for a size Medium.

MIPS was developed by brain surgeons to reduce rotational forces on the brain upon impact during real-world cycling accidents. A patented slip-plane inside the helmet allows the helmet to slide 10-15 mm upon impact, cradling your head to reduce the friction coefficient redirect the force of the impact, while still allowing unobstructed ventilation.

Light Weight Offering

Had the Cinder. Was looking for something a little lighter. This fits the bill. Less neck ache. Haven't really worked out how my Ray Bans work with the sun glass retainer. The retaining strap seems better as well. Fit is consistent with Giro.

Saved my life- twice

I've had two of these helmets. Bought the first one in 2015 and about a year after purchasing went down on some train tracks it the rain. My head bounced of the track pretty good and the helmet took the brunt of it. Got a replacement through Giro's crash replacement program, which at 40% MSRP. Went over the bars today landed hard, and cracked the second one in two places. Can't say enough about this helmet or Giro in general. I have been wearing them from 25 years as they just fit my head really, really well right out of the box so that's huge as far as protection is concerned. I have probably owned 20 Giro helmets (road and mountain) since 1992 and the Synthe is a great helmet, not noticeable when you wear it, very comfortable. I've wanted to check out POC and Kask but have had such good luck with Giro, there's really no reason for me to switch. Typically I'll average between 3-4000 miles a year on a bike, depending. Going to get another one of these or maybe an Aether.

Well designed high end helmet with good construction, attention to a rider's expectations.

Have been riding for 30 plus years and have had prior Giro helmets. This product is very light, almost to the point where when wearing it is not noticeable, does not move around the perimeter of the head, has little to no interference with the rider's view from side to side. The enclosure is very snug and well fitting, though without any need to overtighten to bind to the rider's head shape. Giro has finally figured out how to create a helmet that even after long rides of over two-plus hours, the unit does not feel heavy, cumbersome, or need continual adjustments - something I have had with other high-end helmets and gear. The straps are not too long and are easy to adjust, the same for the dials to set the inner enclosure.

Love my new helmet.

I ride between100 and 150 miles a week. My helmet is very comfortable and extremely light. The airflow helps keep my head cool. The interior lining is comfortable and the helmet can be easily adjusted. I recommend this helmet wholeheartedly.

Comfortable fit, great airflow, light weight. I live in Louisiana where superior ventilation characteristics are a must in the heat and humidity. This helmet has what it takes.

SAFE Helmet

I am a 72 year old road and trail rider and have been riding 31 years. After using several helmets over the years and noticing many improvements I purchased a Giro Synthe. On the second ride I had a road accident where I hit my shoulder and then my head. The shoulder pain was excruciating but my head did not hurt and it was later in the day when I found two big dents in the temple area of the helmet. Without the Synthe I do not know how bad the injuries would have been. Thanks to Giro for making SAFE products.

The Giro Synthe really lives up to it's claims

This is the second Synthe I have owned. I tested my first one and competitors for cooling in a makeshift way at the Portland warehouse store. Cooling was a high priority for my selection since I ride hot in the summer. I use a Giro cap under it for cooler weather. On my first ride while going down a fast hill I had descended many times before, I had the distinct sense that my head felt more free in the passing air. My speedometer confirmed a small but noticeable gain. The other reason I chose this helmet was the very comfortable fit. The best I found for me.

So why am I on my second helmet in two years? It was the other reason for selecting the Synthe that I simply took for granted. I crashed at 18-20 mph. It seemed like a perfect 5 point landing and had the bloody scrapes on my knees, elbow, hip and shoulder to prove it. I thought I might have glanced my head, but the helmet seemed to have only minor cosmetic damage. I wore the helmet on the next ride and laid it on the table at the break. One of my fellow riders noticed that the helmet was now split at the back. It likely saved me from a concussion or worse, and I did not even know it. I am sold on this helmet!

Highly rated for crash protection, lots of cooling, and lightweight

I crashed last March (2019) and that pretty much destroyed my old expanded polystyrene (EPS) helmet. While the EPS mostly did its job (I wouldn't be here to write this review had I not been wearing it), I did end up with a concussion. Needless to say, safety and overall protection for future crashes (yes, they WILL happen) was foremost on my mind. But I also wanted to get a helmet that was comfortable, had great cooling, and was reasonably lightweight. For an independent look at safety, I studied the Virginia Tech Bicycle Helmet Ratings (httpswww.helmet.beam.vt.edubicycle-helmet-ratings.html). The Synthe MIPS is among their five star helmets (their highest rating). For other features, I read many reviews (best helmets of 2019, etc.) and the Giro Synthe MIPS helmet seemed to be one of the top picks in several of them. I've been back on the bike now for about two months and have worn the Synthe MIPS for every mile. So far it's everything I had hoped it would be - lightweight, comfortable, and cool. I hope never to test its protective features to their full extent, but if I do, I'm confident it will do its job.

Great upgrade to my old Giro

I spend 300 hours a year on my road bike. We've had a number of crashes in my club this year and it made me think about the MIPS technology. I'm in right on the cusp of medium and large. Did the measurement and went with medium, which turned out great. Have just enough room for head cover if needed.

Perfect upgrade

I stick with Giro helmets as they always seem to fit me well, and this was an upgrade from my last helmet. It's light, fits great with or without hatsheadbands underneath, keeps nice and cool, and the color scheme I bought is a great match for my bike. Only has a couple of the removable inner pads, which frankly I like as there is less to lose, and there is no compromise in comfort. I couldn't be happier with this one!
