Performance Innovation.

The Giro Aether MIPS Helmet marks a revolutionary leap forward in rotational energy management. Inside the Aether, a dual-density EPS foam liner helps manage a wide range of impact energies, while also boasting deep internal channeling to provide cooling airflow. Giro's proprietary MIPS® Spherical technology is integrated between the layers of EPS foam - instead of against the rider's head - giving riders the benefits of MIPS without obstruction to comfort or cooling power.

The stunning silhouette is formed by a sleek six-piece shell that surrounds a series of massive vents, with added structural reinforcement via a shatter-resistant AURA reinforcing arch. The final touch is the Roc Loc 5+ Air fit system, featuring 3-way fit tuning, that allows for easy adjustment in seconds.

Features:

  • Sleek road helmet with 11 vents and Wind Tunnel internal channeling for optimal comfort and breathability.
  • Shatterproof Roll Cage "Halo" Reinforcement.
  • MIPS Spherical technology shifts the MIPS system between the EPS foam, rather than next to the skin.
  • Featherweight webbing with Slimline Buckle.
  • Sunglass docking ports in front vents.
  • Ponytail compatible.
  • Compatible with Roc Loc 5 LED (sold separately)

Great flitting helmet

I am an avid cyclist. My rides are long and often. I have not ridden with this helmet yet, but the size is perfect. I am between a medium and a large and chose the large for when I need extra warmth for my head. The retention system works great and is very easy to adjust. I highly recommend this helmet to anyone who is wanting a fantastic helmet.

Expensive, but an excellent road biking helmet.

This is a fantastic-fitting helmet, with a wealth of adjustment points and long enough straps that it's good for my big melon. I love the Spherical addition to the MIPS liner this has to help with impact dispersion in a potential crash, which I hope I never have to test. It's also very light and airy, making it a joy to ride with because you don't hardly know it's there and it breathes well on hot days. Looking forward to trying the companion light for it.

I like my helmet

It will fit Aether Helmets. Bought 2 Aether helmets & 1 light. I would not fit on my wife's helmet but would fit on mine with a loud click. the defect is in the Rock Lok system. Hers is a few millimeters thinner than mine. So upon another reviewer's review he Velcro'd the light to the Rock Lok 5. I did the same. IF you buy the Rock Lok 5 light & it will not properly snap into place. Use the 7/8" square Velcro tabs then cut them in 1/2. Attach to light first then to Rock Lok where it is suppose to go.

Buckle up with top-pof-the-line helmet

As others have already stated the Giro Aether is a fantastic helmet. Light, well ventilated, MIPS, and looks great. I've had problems with the fit on other Giro lids (LAS and Smith helmets tend work better for me), but the Aether is altogether different. The helmet is highly adjustable with strap anchor points that can be moved to adjust the fore/aft positioning and make the webbing feel narrower or wider. Sizing appears to be accurate. It's a bit disappointing that such a pricey helmet doesn't come with extra pads (which wouldn't cost much as the padding is quite sparse). Still, given all the features the price is reasonable, especially if purchased during a BTD sale. I like to rinse my lids after each ride, and since I hate putting on a damp helmet I have a rotation of several helmets. I ended up buying two Aethers (in different colors) and will retire some of my older helmets.

I forget I'm wearing it...

I've crash tested two Giro Synthe Helmets - both saving me from much nastier injuries. Alongsiiide the safety aspect they were great helmets for keeping me cool, particularly in the hot climates I ride in (Egypt, California, Australia).

I couldn't get the Synthe anymore and finally found this Giro Aether Spherical on BikeTiresDirect for a fantastic price - after visiting more than a dozen brick and mortar stores, and at least that many other online retailers. I was not immediately a fan of the shape (the front) but the helmet is so comfortable, I really don't notice it at all. The strap placement works well for me and the sunglasses ports were something I was keen to have again after the perfect ones on the Synthe.

As for the additional safety of the MIPs spherical, I hope I never have to find out how good it is first hand but I am impressed with how the system doesn't interfere with the airflow or make the helmet bulky. I got the Black FLash version and am glad to have the light reflecting decals. With my history, perhaps I should have bought 2?

Great comfortable helmet

Is there a helmet more awesome than a Synthe? The Aether is it. Super comfortable, lite, and ventilated. I held off buying a first gen MIPS helmet so I can't compare, but the Aether is the best helmet I have owned.

Helmet delivers.

True to all the other Giro helmets I have owned this helmet checks all the boxes. Fit is similar to the older Synthe it is replacing but there does seem to be something to the Spherical tech business. Seems the higher up you go the helmet is also lighter. No neck issues on longer rides. Grey straps may show less fading, I hope, than standard black. Good sunglass holders and wide vents are good for head scratching.

Exceptional Helmet

Put it though the paces last week with a 36-miler and today with a 100K (cold, wet miserable ride)....perfect fit and extremely light, great ventilation coupled with solid aerodynamics. My ONLY compliant, this is the only high end helmet (yes, at this price point...it is high end) out of too many to count in the past 3-years that DID NOT come with replacement sweat pads.....Come on Giro...

An Excellent Helmet

I am a recreational road rider, with most rides in the 20 to 30 mile range, and occasionally twice that. I like the lightness, ventilation, and compactness of this helmet. Even on sale, it is not cheap, but it looks great and fits my head very well. Over the last 15 years, I have used both high end Giro helmets and Laser Helmets. For a number of years Laser had a definite edge in fit and comfort, but now I prefer the Aether. I think the big difference is how the helmets handle the MIPs technology. I find that many MIPs helmets exert a wierd torque on my hair. Aether does not.

Great helmet

Replaced an older mips giro with this one. The MIPS is totally integrated and out of the way. Fit perfectly right out of the box. Several months of use and seems great. Last Giro mips saved me from any head injury in a 55kph crash!

Excellent Helmet!

I have used Giro helmets for years, the recent being an Atmos. I really like the Aether. The adjustments are very good and easy to make. It is very comfortable and light. I like the new safety features, which is why I upgraded...it had been about 8 years since I had a new helmet and my wife was suggesting I get up to speed with the new technology to protect my head.

I would highly recommend this helmet. Expensive, but when one considers the importance of head and brain safety, it was worth the spend!

Good looking helmet and a custom fit

This helmet is high quality and fits really well. If you havent used a MIPS helmet it's a tad larger on the sides than the older style Giro I had for years, but it looks great and is not noticeably different in size while riding. It sits lower around the brow area so it can apply slight pressure to your riding glasses, but not a big deal at all after adjusting for it. Now other riders helmets appear to sit too high on the head I have noticed. Great rubber grippy spot to put your riding glasses if out near dark. I would purchase this helmet again.

Loving the Aether

First of all, a huuuuuuuuuuge thanks to the wonderful folks at BikeTiresDirect!!! They were extremely helpful and understanding during the purchasing process, as it took two exchanges before receiving the correct size/brand helmet. Thanks BTD, you guys and gals absolutely rock!!!

As for the Aether, I ultimately ended up with a size small and it fits my bald head perfectly. I always wear a skull cap under my helmet (for warmth in the winter and for sweat management in the summer), and the size small Aether still provides plenty of room for that layer in between my head and the helmet. So far I've only worn it for one 30-mile ride, but I can already tell that I'm going to love this helmet. It's super comfortable and feels very light atop my head. Other than the straps under my chin I was pretty unaware of the Aether during my ride.

Aesthetically the Aether is a 10 out of 10. It looks great IMO, not too bulky, fairly low-profile even with the MIPS layer, and it does not look like a big mushroom on my head.

I really hope I never have to personally test the crash protection of this helmet, but if I do I can be confident that I'm wearing one of the safest helmets on the market. The Aether is not inexpensive, but I think it's well worth the cost.

Excellent helmet - incremental improvement from last one

This fits like the prior Synthes, overall. It allows great air flow and I love the neon yellow color. I had a 4 year old non-mips Synthe that is beyond it's useful life, thus bought this. The straps are secure and don't collect sweat. The padding is light but supportive. The two-part design is something I don't notice at all, hope that's a good thing. The only gripe is the front plastic part of the cage leaves some indents on my forehead when I use it, even allowing sun in to give me an odd forehead sunburn during summer. Fall riding so far has been good, not needing a beanie hat so far and still very breathable.

I would purchase again, although expensive, I'm trusting the safety tech is worth it.

Nice!!

I've been wearing Lance era Giros since uh, Lance. They've always fit great compared to other brands so I've stuck with them. This is the first "different" model for me, and holy cow! It fits soooo much better than my last Giro. I've had broken retention systems in the past, called them, and replacement parts sent to me no hassle. Good company and great products!

Buy this helmet, you will love it.

This is my road bike helmet. I have owned it about 3 months and love it. My head is big (ask my wife about that), but it fits well, even with a cap on my head. The adjusting knob moving easily, click, click, click. The helmet is well ventilated, and keeps me cool (I bought the white version), which I appreciate as temperatures rise here in SE Washington The helmet is light and feels like it not there. I use a glasses-mounted mirror and the rear view is unobstructed. Last thing, I bought it to replace my 3-year old Giro Synthe because BTD had a killer discount - so I pulled the pulled the trigger (in a figurative sense of course) and bought the Aether - worked out well so far!

Giro always fit my small but this model squeezes above my ears too doggone tight.

It's like my heads too round for it or the size small helmet design has changed. The thin sweat rag I have to wear in summer seems to soften the discomfort experienced. Maybe with cooler temps my head won't expand as much and the Giro comfort will return.

Cool and Comfortable

The fit of this helmet in size Small is the same fit for me as my Giro Synthe (non-mips). I feel it is true to size. I bought the helmet for the added safety and also hoping that it would be cooler than my Giro Aeon or Synthe in the Texas heat. I wore my new Aether tonight in 92-95 degree heat and I could feel the cool air flowing across my head. It was almost like an air conditioner! The helmet is noticeably cooler than my Giro Aeon. I will continue to reserve my Giro Synthe as my winter helmet. The Aether is very comfortable and I certainly did not notice the few extra grams (apx 35) between it any my other Giro helmets. Adjusting the helmet is super easy and I love the new Roc Loc and the sun glasses holder. Highly recommend!!!!

Nice upgrade over the Synthe

My Giro Synthe helmet was ready to be replaced and I had been drooling over the Aether, so, at a big % off, it was great deal. The Aether has the MIPS technology built in to the helmet instead of being attached to the already made helmet, so the entire interior of the helmet rotates to absorb shock in case of a crash. This seems much better than the Synthe. Fit is very good. I've only had one ride in 85 heat and the ventilation was good.
