Description Ultra Light. Great Protection.
The compact form of the Synthe MIPS® slips through the air with ease across multiple yaw and head angles, and offers impressive cooling power. Key features include the Roc Loc Air fit system with 2-way fit tuning and Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride. The Synthe MIPS® also has the Multi-Directional Impact Protection System, which we believe can redirect energy and provide more protection in certain impacts.
The Synthe MIPS has the most efficient aerodynamic profile of any of Giro's previous road helmets, yet it has greater cooling power than their lightest weight Aeon. In fact, it's almost as cool as a bare head over 30 minutes according to Giro's test results.
Perfect Fit + Ventilation = Giro Synthe MIPS
This uncompromising design is made possible thanks to a wind-tunnel aided design that uses integrated mesh panels to reduce drag and internal ventilation channels working in tandem with a Roc Lock® Air fit system that effectively suspends the helmet just over the skull to improve airflow.
The fit is micro-adjustable with a one-handed dial adjuster, and the X-static padding keeps it plush and fresh. Among the 19 external vents, there is also a dedicated sunglass docking port to stow sunglasses when they're not in use, and featherweight webbing with a Slimline buckle help keep the weight of this helmet down to a claimed 270 g for a size Medium.
MIPS was developed by brain surgeons to reduce rotational forces on the brain upon impact during real-world cycling accidents. A patented slip-plane inside the helmet allows the helmet to slide 10-15 mm upon impact, cradling your head to reduce the friction coefficient redirect the force of the impact, while still allowing unobstructed ventilation.

It's keeping my husband's head safe!
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.

Best helmet I have owned
by SaaSy Cyclist

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.

Great fit and protection.

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.

From Atmos to Synthe MIPS.
by avmartel
Competitive Racer
Minneapolis, MN
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.

Excellent helmet!

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.

Really, really good fit
by Alajandro
Cycling Enthusiast

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.

Even MORE comfortable than the Savant
by PJF
Cycling Enthusiast
Essex, CT
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.

Very nice helmet!
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!

So Far, So Good!
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.

Great Helmet
by Anonymous
Chicago suburbs
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.

Saved my head in a crash
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.
