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.
Lightweight. Cool. Great airflow. Great helmet for south GA heat. Best helmet I have owned.
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!
It just looks fast! I love this helmet. I inherited my mothers large head so it looks like a normal sized one when I wear it. Excellent styling and stoked about MIPS.
I love the helmet. I can barely tell it is on, very comfortable and light.
Use every time I ride my bikes,adjusts very easy, lite weight and painting is nice on the helmet
Use it every time I ride bikes, lite weight, cool when using, adjust ease, looks good.
Had accident on bike where helmet structure cracked upon impact, but I received no concussion.
The MIPS probably takes the credit for my good luck.
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.
I have been using Giro helmets for almost 20 years including the Pnuemo, Atmos, Ionos, Aeon and now the Synthe MIPS. The Synthe is the most comfortable helmet I have ever worn. It is not as light as the Aeon but because of the fit and the excellent ventilation it feels as light. I ride 200 miles a week in the Phoenix Az area and really appreciate the fit and ventilation of the Synthe.
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 have not worn it on the bike yet, but I have tried it on and it fits great like all of my previous Giro helmets.
Best MIPS aero helmet! I have had a few others and none compare to this. Keeps head cool, while keeping your melon safe!
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!
This is my 3rd Giro Synthe helmet. The 1st 2 were banged up in wrecks, and I am very glad I was wearing a helmet, and especially this one. I am looking forward to trying the new model that is on backorder.
I bought this for my husband as he had cracked his previous helmet in a nasty cycling accident. He's very happy with this helmet, and I feel it is keeping his head from getting injured if he were to have another crash.
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
Best helmet yet...quiet in the wind, light, comfortable and all the other positive attributes listed in the marketing promo. I've, unfortunately, broken two Giro helmets (not this model) in crashes but didn't suffer head damage in either. Giro helmets have saved my skull. The reason this doesn't get 5 stars is due to the adjustment knob which is small and can be difficult to adjust while riding with sweaty fingers and more difficult if you're wearing gloves.
I wanted a Mips helmet and this helmet has the best features of all the helmets on the market today. I also have a POC Miips helmet which I like but its not quite as nice looking and feels slightly heavier. I have owned Giro helmets in the past and this one fits as well as any high end helmet. The vents are great and the air flow has to be better than the Smith Overtake. The other thing that sold me on this helmet is its rounded back. There are articles out there that say helmet with pointed backs are more prone to stick on hitting the ground versus a rounder one which will roll.
