Fit and feel of this helmet is great. Aero, but not too hot.
The reason I really love this helmet is that it saved me from a crash at 30mph. Downhill, sharp turn, wet leaves, into a wire fence, you know the scenario... Hit my head and didn't even know it until I saw the damage on the front of the helmet at the end of the ride. No concussion, no loss of consciousness, no head pain at all in fact. helmet smashed up on the front, but still intact. Ordering a new one again!
This is my second Synthe, as the first one did its job last year and kept me away from the neurosurgeons when a car took out our paceline (do NOT reuse a helmet that has been in a crash!)
I live where heat is an issue, which is why I bought the original helmet. The colors I ordered matched my then-bike well, and the design was not at all displeasing. Function with style. My noggin did not overheat, and even though I am a little follically challenged, no sunburns up there.
The straps are easy to adjust as is the dial adjuster in back. I race (amateur) and am pretty sure that the helmet is as aero as Giro claims it to be any marginal improvements other brands may make would certainly need someone much closer to the pro ranks to see enough of those gains to make a meaningful measurement.
As stated above the helmet served its purpose and saved my skull from a closer encounter with asphalt that it did have. I was so impressed with the helmet's performance before and during (in retrospect) the crash that I knew another was in my future. Now I have MIPS, so its even better! I don't have a $20 head, so I spend money on helmets.
Good crash protection, very aero, comfortable, and cool.
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!
I've been using Giro helmets since the first model came out with the hairnet cover. At least two mountain bike helmets, a couple of Atmos, and now the Synthes followed.
I bought my first Synthe MIPS because it was so damn comfortable finally a helmet that fits!
I bought my second Synthe MIPS because when I crashed the first one very hard I had never felt a softer landing from a helmet (and Ive broken 4-5 over the years.)
Added plus I like the color (matte whitesilver) and I got it on sale. A whole-hearted recommendation.
I had been using a Savant MIPS, upgraded to the Synthe MIPS when there was a sale, and love it. It's so comfortable I hardly even think about it while riding, other than occasionally adjusting the micro adjuster, which I can do on the bike. The micro adjuster is extremely handy to compensate for the change when I put a skullcap on or off in the winter. I also like that the height of the rear band mount is adjustable, easy to get the fit snug but not tight. The sunglasses dock seems mainly useful for pros (who have sunglasses sponsors) or folks who wear cheap sunglasses. Me, I need glasses to see where I'm going so (a) I'm not going to take them off while riding and (b) even if I did, they are Transitions Progressive lenses, which are FAR too expensive to risk leaving perched on the helmet where they might fall to the ground if I forgot they were there when I removed my helmet. And if they fell off and broke, finding my way home would be a problem! So I just keep my glasses on and fasten the helmet straps over them.
I am sold on MIPS after crashing and seeing how the impact force was distributed. Broke the helmet and didn't feel the impact as much as I had expected. I immediately replaced the helmet with a new Synthe MIPS. My prior helmet was a Giro Pro-light which was not as heavy as the Synthe, but I consider this a fair trade-off, though I do miss the lighter helmet.
This is a great light helmet with excellent ventilation and improved safety utilizing the MIPS system. This is my everyday helmet and I recently wore it while racing at the National Senior Games in Birmingham, AL finishing on the podium twice.
Hi, I've had this helmet-in all black-for a few months and I've really enjoyed it's quality. It's very breathable and comfortable. If you happen to be considering buying one, I have no regrets with my purchase of it, and if you do get one, you shouldn't have any regrets either.
Did a lot of research on road helmets and this particular one is at the top. Fit and adjustments is outstanding. Ventilation is amazing. Aerodynamics again is at the top. I am really glad I made the purchase and would recommend for serious riders.
This was a replacement mips helmet.
I had a POC MIPS Orange helmet that was compromised on a charity off road event.
This helmet fits better, and feels like you are not wearing one. Bought the yellow which has great visibility.
Had not had a Giro helmet for many years.
I am a fan again!
I wore two Giro Savant helmets over the last 4 years but recently decided to upgrade to the Synthe. I chose the Synthe because it seemed to have a cool, sleek, more modern feel to it, and the color choices were excellent to boot. After riding with this helmet daily for a few months now, I can say for certain that its awesomehowever, Im not sure Id purchase a helmet online again without trying it on in person since this helmet feels just slightly smaller than my old Savant did, even after adjusting both the rear dial and chin straps. That said, Id still recommend this helmet to anyone looking for a higher quality upgrade.
