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!
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!
This has been on my wish list for a while to replace my Air Attack so I grabbed one while they were on clearance. The Air Attack is a size large and it's a little big unless I wear a winter cap underneath it, so I opted for the medium Synthe. The Synthe fits snug and won't work with a winter cap, so maybe I'll keep the Air Attack around for cold days.
Overall it's a great improvement in comfort and weight. It's been too cold to test ventilation but it can't be worse than the Air Attack.
When I tested this helmet in my garage wind tunnel I measured it to be 4.67% more efficient. But seriously, the helmet fits great. The Giro adjustment knob works great as usual. When I first picked it up I was surprised on how light it was. Lastly, the sunglass garage works great and keeps my glasses safely in place, unlike all of my prior helmets. Lightweight with great features and MIPS protection, how can you go wrong.
The fit and feel of this helmet is supreme and a big improvement over my previous Giro helmet. Overall riding experience is great, quieter in wind noise, plenty of air flow pouring through. Having a MIPS design helmet i think is what really sets this apart in the comfort department as well, big improvement. I am very satisfied with this helmet!
I purchased the Giro Synthe at a rocking good price. This is a gift for my wife. Not only does it look great without that mushroom profile, but it is comfortable, aero and designed well with a MIPS system for safety. I highly recommend this helmet if you want a race worthy and safe helmet. Go Giro!
Just FYI, if you have a large (size 7-12 or larger) head, this may not work for you, as the MIPS liner takes up room inside the shell. With a thin skullcap on my head, I was unable to get it to fit comfortably, even after adjusting the retention mechanism downward and opening the dial adjuster all the way. As a point of reference, I normally wear a large Giro Ionos or a large POC Octal (non-MIPS), both have plenty of room. BTD handled the return quickly and with no problems at all.
I usually wear M in Giro helmets and this was true to size. It's comfortable and quiet. I prefer fewer vents for fewer yellowjackets and less sunburn (like Air Attack) but Giro was between aero helmet styles so I settled for this in order to have a freshly made helmet. EPS has a shelf life! I wish it had some quality reflective material. I added 3m SOLAS but it should come from the factory that way. The only negative is that my Tifosi Tyrant 2.0 absolutely will not stay locked in the vents, front or rear. I haven't tried it with other sunglasses because... These are the ones I have. Too bad I can't stow them on this helmet.
This is a nice helmet, it should be for $. While it is lighter than my old Scattante Spyder helmet it is not any cooler. I expected it to be at least a little cooler but the sweat still pours down my forehead like before. How much do I have to pay for helmet where this is no longer an issue?
After a head injury incurred in a crash I wanted a MIPS helmet when first saw them. Th Synthe was my choice. This has been my second season with it and here are my observations
Fit - typical of all Giro helmets and for me that means secure, comfortable and sleek looking. The adjustment mechanism is excellent.
Weight - not the lightest but still quite light.
Usability - sunglasses (Oakley) for perfectly - unlike POC where the glasses stems are too long for the helmet. Helmet does not slide on the head but stays comfortably snug. Airflow seems fine although I rarely feel hot due to a helmet.
Only peeve is no extra pads came with it and in spite of the pads being minimal, replacement pads seem far more expensive than those for any other Giro helmet
