Light, comfy. Looks amazing and has perfect holes for sunglasses. Super easy to adjust.
Cool when riding in the heat. And quiet.
Super product from a great shop.

This is by far the most comfortable helmet I have ever tried on. I tried on several from other major competitors and none could compare. The cushioning is minimal but provides just what is needed, and the cinching system adjusts nicely to create a supremely comfortable fit, while benefiting from the MIPS technology. I do wish Giro had included extra cushioning strips as they had with previous helmets I have owned.

I'm on my third Giro Synthe Mips. They fit me really well, are incredibly lightweight, and protect your head really well. I've had a couple of serious knocks in the head, serious enough to warrant a new helmet, and the Synthe Mips protected me head really well.

After 5years of use had to retire my trusty GIRO Atmos...Hello Synthe! Lightweight, good aero profile while very well vented and MIPS tech upgrade are all quite welcome. The interior is well cushioned and the straps are snug and comfy on your face. the dial ratchet is really adjustable and works better than the Atmos press-on system. Color schemes of all types avail..my white red orange gets plenty of nice lid remarks during training rides.

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.

This is a great helmet. I have an older version as well. My Smith glasses fit perfectly.
Review by Bike Dogter
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.
Review by TexasCyclist
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.

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.
Review by Dave Christ
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.

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.
Review by Becky Lowry
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.

Purchased a small for my wife. I think the MIPS system makes the fit a little tighter, which is good for her. The red and white color is very nice.
Review by Alajandro
Probably the worst that I can say about the Giro Synthe MIPS is that I have to check make sure I am wearing it. Its a great fit and easy to adjust and coupled with its low weight, can forget that I'm wearing it.
Also MIPS adds additional confidence in reducing severity of injury.

Not an expert on helmets, and not a serous high mileage rider, and fairly new to cycling, but love high quality gear! This helmet seems well made & really lightweight. In the end I decided to try the POC Ventral air spin instead, as I love the looks, European & elegant! It's just a personal thing, but both seem to be of very high quality! Cheers!

This is my second Synthe MIPS. Well ventilated, light, comfortable straps and easy adjustment. My one minor complaint is that Giro seems to have used the same mold and just inserted the MIPS so being on the cusp of small and medium, I had to size up to get anything more than a Really thin scullcap underneath. This is now my late fall/winter helmet.
Review by Tom
The fit and feel of the helmet is great. Decent airflow and a spot for my sunglasses. The only minor issue is the front padding. It turns into a sweat pad on hot, long rides and will drip down onto your face. I've remedied that by just wearing a cycling cap beneath on hot day's.

This is the third Giro Synthe helmet Ive bought and the second with MIPS. The fit is great and it looks great, too.
Review by Allan anderson
This is the second Synthe mips helmet I have purchased for my wife. Last one was damaged in transit while stuffed in a suitcase. Inner fitting system broken and not replaceable I this helmet. Great style, fit, weight, and safety. I wear one also.

After I ordered, I wished I had a visor for when I go mountain bike riding, but really I wouldn't change a thing. This helmet was a HUGE upgrade than my current helmet.
