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.

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.

Top of the line HELMET!

This helmet not only replicated its predecessor, the Synthe but also adds so many new features that make road riding even more efficient and enjoyable! Venting is upped with numerous more vents. The new MIPS design allows for even more fluent movements when and if impacts are experienced. The fit is phenomenal and lighter. Overall excellent offering by GIRO and BTD.... Very satisfied!

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.

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!

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!!!!

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...

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.

This is a GREAT helmet

I use the helmet on all my rides. It is light and comfortable, and fits my head without any undue pressure points. It works with all my Oakley sunglasses. I have used several winter caps under it, and with a twist of the knob it adjusts for a perfect fit.

I crashed once, but did not get to test the helmet as there was no head contact with the ground. I hope to not test the helmets crash worthiness.

Best Helmet to date from Giro!

Ive been an avid cyclist for 35 years averaging 500 miles per weekalways with a helmet properly attached to my head! Over the years Ive had every top-end helmet produced by Giro. The Aether is by far the best helmet Ive had! While I cannot attest to its crash durability and protection, this helmet is very comfortable, easy to fit, and highly ventilated. In all previous models, I had to wear a headband to prevent sweat from getting into my eyes but not so with the Aether. Its air channeling is simply the best. For those who ride at night, a taillight and headlight can be attached to the helmet without interfering with the MIPS liner.

Best helmet I've every owned

I've worn Giro helmets for as long as I can remember, and the thing that is most outstanding is the fit. However, in recent years some of the retention materials of Giro helmets have become marginal and I find the useful life of these expensive helmets to become quite limited. Having said that, someone at Giro must have gotten the message because the Aether helmet is definitely built with much better quality and materials. The design of the helmet within a helmet is revolutionary and makes this not a superior safety device but more comfortable for long rides as well. I must say you pay dearly for these features, as this is more than I've ever paid (or hoped to pay) for a bicycle helmet. But considering all the safety and quality, I say it's pricey but definitely worth it.

Excellent fit, comfort, and ventilation

I bought this helmet after buying a cheaper Giro model (Syntax). Although the Syntax was fine, I felt it lacked ventilation. SInce I'm lucky enough to have a son with the same sized head, he got the almost new hand-me-down, and is thrilled with it. He's a casual rider, I'm a road enthusiast.

The Aether, as hoped, is extremely well ventilated. It's quite pricey, but if you catch the BTD sale, you can just justify the price for that high level of comfort.

Helmet fit is something that will vary by individual, as we all have rather different shaped heads, but I find the Giro fit to be the best among the brands I have tried. I measure right in the middle of the M range, and I can literally wear the helmet right out of the box! The RocLock system provides an excellent level of precise control over fit - so much better than the bad old days of placing multiple adhesive pads to try to get a decent fit.

I love my Giro Aether MIPS helmet

I am so happy to have purchased my Giro Aether MIPS helmet from Bike Tires Direct at a great sale price. I would have missed out on this great helmet had it been selling at a higher price.

My head measurement is just slightly under the max recommended size for a medium helmet. The medium fits me perfectly. It has a slight amount of room before I ratchet it down a little to fit me perfectly snug.

My old helmet of another brand was too large for me in the first place. I always wore a sweatband on my head to capture sweat but mostly wore the sweatband so that my helmet would not slide around. It's so nice to have my new helmet fit me so perfectly where I don't need to wear a sweatband. The Giro Aether MIPS helmet does have its own thin sweatband on the front. It's really too thin to capture much sweat. I haven't read anything about its ability to channel sweat but it seems fair at doing so. I occasionally have sweat drop down onto my sunglasses but my sweat often channels off to the right and drips down past the far side of my right eye.

The ratcheting mechanism for tighteningloosening the helmet works nicely. I get a perfect fit. The helmet also feels cool and light as advertised.

One last thing - The fit system of my old helmet would sometimes push onto my glasses frame by the ears causing some irritation. I have no such issue with my new helmet. My new helmet fits and feels great.

Aether MIPS - Pretty slick helmet

I use this for road riding and am pleased with the helmet's performance (although I haven't tested it for it's intended purpose of crash protection). I like the ventilation at the front of the helmet, the air coming through the vents is very noticeable although it seems like the airflow over the back of my head is not quite as plentiful as on other helmets I own (Bell Zephyr, Giro Aeon). The fit is great for me (I wear a medium) and the roc loc system works well. This helmet seems to sit further down on my head than others and I like the additional coverage but it sits low enough that it interferes with one pair of sunglasses with larger frames. While I read they claimed it is less bulbous than it's predecessor, from a style perspective it still hews to the mushroom head look.

The mips helmet advanced design to have, and hopefully never to utilize.

I have enjoyed the comfort of the Giro Foray mips helmet for sometime. However, when I recognized the technological advancement of the Giro Aether mips model, from a safety standpoint, the only logical conclusion was to purchase the Aether model.

Since purchasing the Aether model, I have worn this helmet dozens of times over hundreds of Colorado roads this summer. The Aether helmet is noticeably lighter and more comfortable than my Giro Foray helmet, yet fits snuggly with the adjustable wheel at the back of the helmet. As advertised, the flow through ventilation of the helmet has kept me cool, even on some hot afternoon rides.

When you read the advanced safety features of the Aether model mips design, you realize this is the design to wear, but hopefully never to depend upon. One problem with this helmet now I have to purchase the Aether helmet for the rest of my family cyclists.
