I ride 20 miles on the weekdays (2-3 days per week) and 35-50 miles a day on the weekends, so I am in my helmet quite a bit. I love the fit of the cage on this helmet - it is very snug. I also like the materials that are used for cusion - they are not absorbant and seem very durable. About the only negative I can find is that there is a structural band that goes from left to right across the helmet that limits attaching lights to your helmet if you do early morning or late night riding.

Great fit, excellent air flow
Review by GDS-PDX
The Giro Synthe is an all around great helmet. It's light and breathable, yet it feels really secure on your head. It can easily accommodate a cap with the visor flipped up, yet somehow also sits nicely low on my forehead. The venting is very good yet the helmet it quiet and does not create a lot of wind noise. I'm very impressed!

Loving the matte black finish to the helmet. Also easily the lightest helmet I've ever had. Fit adjustment works great, and the MIPS seems like it would work. Really loving the sleek look that Giro puts out.

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.

This is definitely the best helmet I have owned. Very comfortable and nice looking.

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.

The design is awesome and better yet, customer service was top notch. Fast shipping and great prices.

My new Synthe replaced an older Giro helmet. About my fourth ride with it it was put to the test! I got hit by a school bus that was pulling out into the street (without noticing me). Though my head struck the pavement it did not sustain injury, though ribs and collar bone sustained some factures.

On the second ride after purchasing the Giro Synthe MIPS Helmet I had my first bad bike accident after riding for 30 years. I have a fractured humerus, lots of bumps and bruises but coming out with a few dents in my helmet knowing that I hit my head I had no head injuries or head ache. Giro thanks for building this miracle!!

I use this for road cycling and its superb. Being that I have a larger head (thanks mom) it doesnt look like a massive dome on my head. The fit is perfect and I don't even notice it's on my head. Love it!

Multiple color options. I chose blackorange for good visibility and still looks great. Also weight is light which is obviously good!

Excellent comfort and safety! Helmet saved my head in a crash in June this year. I ended up with 5 broken ribs, punctured lung, and shattered hip. No head damage as helmet absorbed impact . I got the new mips version of the synthe but do not plan on any more crash testing!

every ride
Review by AJD
I use it almost every day. It is light, comfortable and cool. On cool days I wear a head cover under the helmet but on warm days I just use the helmet without head cover and it provides a cool ride

I find this to be a very comfortable and light helmet, good ventilation as well.
