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.

Best helmet I have owned
by SaaSy Cyclist
Cycling Enthusiast
Portland, OR

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.

Very nice helmet!
by Anonymous

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!
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.

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.

Excellent MIPSHelmet

Bought to replace non-MIPS Kask Protone. Both good helmets just preferred the updated technology. My head measures 22.5 inches and medium fits me perfectly. Light good looking helmet I hope I never have to test it.

Excellent protection system and great airflow in one package

Purchased this helmet for the safety protection system. In addition it has a great fit and the airflow really does keep your head cool. It is more expensive than some other helmets but well worth the price.

Saved my life- twice

I've had two of these helmets. Bought the first one in 2015 and about a year after purchasing went down on some train tracks it the rain. My head bounced of the track pretty good and the helmet took the brunt of it. Got a replacement through Giro's crash replacement program, which at 40% MSRP. Went over the bars today landed hard, and cracked the second one in two places. Can't say enough about this helmet or Giro in general. I have been wearing them from 25 years as they just fit my head really, really well right out of the box so that's huge as far as protection is concerned. I have probably owned 20 Giro helmets (road and mountain) since 1992 and the Synthe is a great helmet, not noticeable when you wear it, very comfortable. I've wanted to check out POC and Kask but have had such good luck with Giro, there's really no reason for me to switch. Typically I'll average between 3-4000 miles a year on a bike, depending. Going to get another one of these or maybe an Aether.

Well designed high end helmet with good construction, attention to a rider's expectations.
by Jim McCloskey

Have been riding for 30 plus years and have had prior Giro helmets. This product is very light, almost to the point where when wearing it is not noticeable, does not move around the perimeter of the head, has little to no interference with the rider's view from side to side. The enclosure is very snug and well fitting, though without any need to overtighten to bind to the rider's head shape. Giro has finally figured out how to create a helmet that even after long rides of over two-plus hours, the unit does not feel heavy, cumbersome, or need continual adjustments - something I have had with other high-end helmets and gear. The straps are not too long and are easy to adjust, the same for the dials to set the inner enclosure.

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

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.

Had the Cinder. Was looking for something a little lighter. This fits the bill. Less neck ache. Haven't really worked out how my Ray Bans work with the sun glass retainer. The retaining strap seems better as well. Fit is consistent with Giro.
