What do boxing and cycling have in common? Well, not much, actually. But that still didn't stop the engineers at MIPs and Giro from using head impacts in the ring as part of the comprehensive corpus of research that informs the ingenious, impact-diffusing design of the Savant MIPS Helmet.

The Savant is the product of Giro's collaboration with MIPS, a project that took two years and thousands of tests to create a helmet based on biology. The collaboration's goal was to mimic your skull's cerebrospinal fluid, which lets your head's different protective layers move laterally, independently of each other, to diffuse the force of oblique impacts.

The Savant translates this model to exosomatic applications by allowing the outer shell to slide across the helmet's inner basket when tangential force is applied. Instead of just absorbing energy, the helmet's MIPS technology is able to redirect it.

While the tectonic outer shell is the result of an international collaboration, the rest of the helmet is pure Giro. The In-mold construction process fuses a middle layer of polycarbonate to the impact-absorbing EPS foam body to bump up durability without a corresponding rise in weight. A healthy dose of vents and internal air channeling keep your head cool, so you're not sacrificing comfort for safety, and Giro's Roc Loc 5 system uses a ratcheting dial and adjustable fore/aft tilt for unrivaled customizability of fit.

Fit adjustment dial is fragile

    This helmet’s fit adjustment dial broke off on my helmet. The helmet now can’t be securely tightened onto my head. Can I replace the part without requiring a new helmet?

    Great price for MIPS

    • Familiarity: I've put it through the wringer

    I purchased this helmet because it was at a great price point and came with MIPS. As someone who has suffered multiple concussions I wanted the most protection per dollar and I think I found it with this helmet.


      Its a very wide helmet and looks particularly goofy in my opinion. I returned the one I bought and decided to stick with my old one.

      What I Wanted

        This helmet has just about everything you could ask for these days. Comfortable pads, well ventilated, MIPS, looks "fast" and relatively inexpensive. My Pivlocks fit easily and securely in the vents, though they are a little higher than my old helmet. I think the only draw back is that the pads are a little thicker than what I'm used to (which is nice because they're comfortable) but I sweat so much that every once in a while I have to squeeze the helmet against my head to let them drain out. Otherwise it drips down on my glasses. Fit is as expected.

        Adjust all straps for your dome...

        • Familiarity: I've used it several times

        I bought this for my husband, he puts in anywhere from 100-150 miles a week on his road bike. I was eager to get him into a helmet with MIPS technology. Here's what my husband, Diego had to say: "My wife got this helmet for me to replace my trusty old Bell. She said an awful lot about MIPS helmets and how they are the best at protecting brains against TBIs. She also says the acronym TBI a lot, wives/mothers seem to be obsessed with preventing TBIs. I must say that I have yet to crash in this helmet... so I can't review its' effectiveness. Yet. I will say that it looks cool, and fits me well. At first I had trouble with the rear strap, it was digging into the back of my head in certain positions (it's not padded or thicker, like other helmets I have used), but I eventually found out how(my wife showed me) to adjust the strap. I've ridden several times with this helmet and I seemed to have solved the issue. All in all I am happy with this helmet."

        Might work for you but not for me

        • Familiarity: I've used it once or twice and have initial impressions

        Giro makes great stuff, but this helmet was not for me. For one, it constantly pulled out my hair when pulling the helmet off.

        Also, there was too much play on my head (not because of the MIPS system), but this might be a function of my head shape. There was enough play (on my head) that I was concerned that the helmet might get knocked too far off if I hit the deck.

        Lots of people love this helmet, but if you are hard to fit, try a Lazer. If you love Giro helmets, have short hair, and want MIPS at an economical price, then buy this helmet.

        Thanks for the review Tyler! Super helpful to get this feedback out to the community.

        Looks good

        • Fit: True to size
        • Size Bought: Large

        Bought it on sale so i got a good deal. Fits the shape of my head OK. The only thing i dont like about this helmet is the angle of the straps exiting the helmet.....they do not seem to lay comfortably on my face.

        Exactly what I expected

        • Familiarity: I've put it through the wringer
        • Size Bought: Medium

        It's great! It's affordable, comfortable and safe. What more could you ask for in a helmet? I've always liked the way Giro fits and the fit adjustment seems to suck the helmet down onto my head evenly, keeping the helmet in a safe position. When I tuck down into my drops, I don't feel there's any obstruction of my view and I don't feel any pressure on the back of my head/upper neck. The ventilation is adequate and the straps are comfortable. With all of that being said, this is a relatively "affordable" helmet. So, there are certainly lighter helmets with greater ventilation and performance. However, for the price, I highly recommend this helmet.

        Love this...

        • Size Bought: XLarge

        This is my first road bike helmet and I am very impressed. I have a larger head and have always found it difficult to find a descent fitting helmet that still looks streamlined. The adjustments on the Savant are better than anything I have tried before. Excellent fit and the straps don't pinch my ears and glasses. Very happy with this purchase.

        Cool Helmet

        • Familiarity: I've used it once or twice and have initial impressions

        This is a very comfortable helmet. Lightweight and the retention system rocks, hardly notice it's on my head.

        Nice helmet

        • Familiarity: I've put it through the wringer
        • Fit: True to size

        It is light and ventilated, and looks good.

        Great Helmet

        • Familiarity: I gave it as a gift but have feedback to share

        I gave this to my husband, who is quite pleased with it. It's nice and light, and comfortable on long rides. He has a pretty small head and the small fits great -- the adjustment dial works really well.

        The helmet fits better than any helmet I've owned. Color is great!

        Not Bad Could Be Improved

        • Familiarity: I've used it several times
        • Fit: True to size

        The helmet is nice, not heavy at all, much more comfortable and fit better than the Mavic I had been using. The medium Giro had a broader range that the Mavic, with the Mavic I had to be adjusted nearly to the end of the systems reach, not so with the Giro.
        One drawback is the helmet retaining straps. Because of the design the straps do not lay flat to the side of your head, they have a distracting twist to them. The retaining clasp/webbing is made from two pieces of webbing material where one would have sufficed, adding unnecessary bulk under your chin. I would have given 3.5 stars but can't, it is better than a 3 though.

        Mom Approved!

        • Familiarity: I gave it as a gift but have feedback to share

        My Mother is an avid cyclist, but she was still rocking her helmet from like 10 years ago. It was time to upgrade and the Giro Savant totally fit the bill. She has an incredibly small head and the helmet is easy to adjust and fits wonderfully. Great safety ratings and attention to design.

        Saving lives!

          Helmets in general could be the biggest factor between life and death, whether your on the road or trail. A family member of mine used this helmet and request another after their crash. They said it's well ventilated, size fits perfectly on their head and no feed back from their hearing aids.

          Neat helmet

          • Familiarity: I've used it several times
          • Fit: True to size

          Great helmet, great price with nice safety feats. I bought the Medium size and it fits perfectly. Comes with a nice twist'n lock system which makes the fitting even more precise. Not the lightest you will find out there, but all in all, if you are a casual rider like me, you will find that that's not the most critical thing. To me it's safety and this helmet brings it.

          Solid helmet

          • Familiarity: I've put it through the wringer

          Thankfully, I haven't yet had an opportunity to test this for it's intended purpose (knock on wood), but I have worn the helmet extensively. As far as helmets go, this is a great one, especially for the price. It has good airflow, and fits nicely. The inclusion of MIPS technology is nice. Finally, it's a pretty good-looking helmet, which is a plus.

          Great Helmet for the price.

          • Familiarity: I've put it through the wringer

          It fits really well. the Roc Loc system allows you to perfectly dial in to the correct tightness. It is extremely comfy and breaths extremely well. For the price it is a great deal. my two issues are the chin straps are just extremely long.. i trimmed them but it was crazy how long they were and the color i have (matte black) scratches really really easy. But other than that no issues.

          MIPS Works!

          I have been a long time user of Giro helmets and can state from personal experiences (more than I really want to admit to) that they do an excellent job of protecting your noggin. The MIPS seems to me to be a good selling point but today - after crashing and getting my bell rung! - I am glad that I spent the extra money for it. For a helmet that was purchased just over a month ago today it did it's job. I am back to purchase another. Thanks trusty Giro helmet!
