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.
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.
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.
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.
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!
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!
Survived 2 cracked Giro helmets. so prefer to stick with Giro v. other manufacturers' helmets. This time I went with MIPS, which was just on the market at time of purchasing previous Giro Synthe. Giro offered 30% off due to cracked helmet, but off their escalated retail price, higher than MSRP listed elsewhere. Bike Tires Direct offered best deal. Not only was helmet on sale, but regular price was nevertheless competitive with other online vendors. Adding VIP appoints to sale price it was a steal,clearly the best way to go.
This is the most comfortable helmet I've ever worn. It fits better than my old Giro Atmos helmet, which was pretty good in its own right. I suspect the MIPS helmet liner is the reason for the better fit. I have noticed a slight whistle at high speeds strong headwinds, but that is a minor issue.
While the helmet design, fit, and finish is fine. The solution to keep the sweat pads on the helmet doesn't last. It could be a flaw in a run or simply a storage related issue, but half the retainer fitted dots fail on one side. Even worse, Giro has customer support level that replies haphazardly if they even pick up the phone or respond to any messages.
For myself, Giro and the family of brands that are along with them doesn't meet the standards of product quality and support for what is being presented as a superior quality product. This particular helmet is the very first to give me such an issue and the support ensured that I would not purchase another one of their products in the future.
I use this helmet on road and gravel rides. This is the most comfortable helmet I have ever owned going back over 20 years. I wear a large Giro Synthe MIPS Helmet, and my hat size is XL or 7 58 - 7 34. I have had a problem in the past with helmets riding back on my head and exposing my forehead. I do not have that problem now and the helmet stays down and protects my forehead. I like the style look of this helmet. I always wear a cycling hat and they integrate together nicely. If I had to purchase another helmet, this would be the one. Perfection.
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!
