With the Giro Aether MIPS Helmet, safety and protection from an impact is everything. Plenty of performance helmets have MIPS Brain Protection System (BPS), but the Aether has an improved, redesigned MIPS protection system. MIPS BPS is scientifically proven to reduce rotational motion when implemented in a helmet by absorbing and redirecting rotational forces. Until now, MIPS BPS has always been implemented directly against the rider's head with a plastic slip-plane inside the helmet. Aether MIPS, or MIPS Spherical, is what the Giro Aether calls their revolutionized MIPS BPS. So what has Giro and MIPS done differently to improve this system? A dual-density foam liner that manages a wide range of impact energies called EPS foam, surrounds the MIPS so that the MIPS is integrated between layers of EPS foam, all while having incredible air channeling.

Features: 

  • Micro-bead expanded polystyrene material for a sleek and slim silhouette without compromising protection standouts
  • Structural integrity supported by the shatter-resistant and translucent AURA reinforcing arch that runs throughout the helmet
  • Multi-density EPS foam to save weight and manage a wide range of impact energies
  • Integrated docking eyewear ports with rubber grippers to help secure sunglasses

Specifications:
Fit System: Roc Loc
Ventilation: 11 Vents
Safety Features: Spherical MIPS
Color: Black

Giro Aether Spherical Road Helmet (Mattte Black Flash) (L)
All the reviews about this helmet were stellar to begin with, so I figured I would upgrade from a different Giro helmet, especially with more hazardous weather coming upon us fast here in the NE US. The added protection and sense of security was important to me as I plan to ride throughout the winter -- and other riders, pedestrians, and traffic remains a concern, especially when the paths and roads get a slippery in areas. I was pleased to receive the helmet faster than expected, and I was able to take advantage of a first-timer discount which was a real plus, since this helmet seems to be in demand and is not discounted anywhere that I have been able to find. (Thanks, Nashbar!).
The helmet itself is slightly heavier than the Giro Syntax helmet I have been using, and I could tell right away that the Aether is more solid and sleeker looking. I understood the benefits of the spherical design but was not ready for the different feel once I put it on! As the name implies, it feels as if it surrounds your head more fully, almost as if this was a custom fit, since it also felt much more snug, too. This made me concerned about wearing a thermal cap or balaclava underneath, plus leave room for glasses and over-the-ear headphones. I have now worn the helmet for 5 20-30 mile rides, with cap or balaclava, glasses, and headphones, and have had no problem whatsoever. In fact, I forget I have the helmet on once I get going, and I use tight MIPS settings and firmly-clasped chin straps. My peace of mind has helped me rationalize the price! I only wish Giro would have used more substantial, higher quality straps. At least the o-ring is of better quality than the one on the Syntax, which enables me to tuck away the extra length of strap more reliably. This seems like the kind of purchase, of all items, that you don't want to skimp on, and I am very happy with the Aether Spherical!

Helmet Measurements:

  • Wrap a measuring tape around your head
  • Make sure that tape is level from front to back
  • Note measurement and reference Size Chart
Circumference (cm)
XS47 - 51cm
S51 - 55cm
M55 - 59cm
L59 - 63cm
XL61 - 65cm

Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you've got the right size, you can adjust the fit.

How to Adjust Fit:

  1. Adjust the fit system at the rear of the helmet for a snug, secure fit. Some helmets also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.
  2. Adjust the straps so that they sit just below the earlobes.
  3. Adjust the buckle so that it rests against the back of the jaw/throat.
  4. Adjust the interior pads if needed.
  5. Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.

Note: All measurements are provided by the manufacturer and may vary depending on how measurements are acquired.
