The Good

  • Lightweight

The Bad

  • It's big–really big!
THE VERDICT

The Giro Aeon is an unassuming stalwart with some of the best fit, comfort and ventilation in the business. While not quite as ridiculously light as its predecessor, the Prolight, the Giro Aeon offers a user-friendly fit and ventilation that was matched only by one other helmet in the test.

FULL REVIEW

Features
The idea of the Aeon as a logical progression of previous Giro helmets holds true throughout its design. The form is a familiar arrangement of linear strokes that terminate irregularly at the back for that hair-on-fire look. Graphics are understated and generally organic to the forms of the helmet with only a hint of the ubiquitous tribal tattoo-inspired designs. Classy stainless steel-look logo badges are tastefully embedded in three places on the helmet and mark locations where the head cradle and straps are terminated in the shell.

For that shell, Giro molds a lightweight expanded polystyrene foam to a polycarbonate shell.

The Aeon’s head cradle looks and functions exactly like all of Giro’s other Roc Loc retention systems except that the small tightening dial is only slightly larger than an M&M candy and the other elements of the system are heroin-chic supermodel-thin. Likewise, the straps are a very light nylon webbing with hardware all slimmed down to be as light as possible. The minimal padding is only where it needs to be and leaves wide channels for air to flow around the head.

Dimensions
The interior shape of the Giro Aeon is on the oblong end of the scale. It ties the Uvex FP3 as the longest and narrowest helmet I tested. Its shell is of average thickness at the forehead and is the thickest at the side and the top of all the helmets tested. Because of that the Aeon has the highest mushroom factor. Despite the thick shell, the combination of its airy vents, lightweight foam and all its super-slim elements produce the lightest helmet in the test.

Performance
The Aeon unsettlingly appears to have more open space than actual concussion-preventing structure. I noticed that the shadow cast by the helmet sometimes eerily disappears when the sun hits it at certain angles–it’s that airy. And though it also seems to disappear once on your head because of its low weight, the Aeon is actually rather large. Indeed, it looks a bit ungainly on my admittedly narrow, pointy head.

Even though all the comfort features have been pared down to the absolute minimum, the fit and comfort was excellent. As expected, ventilation was also excellent. In particular, on a ride where the temperature peaked at 102 with high humidity, I was surprisingly comfortable. The only fault I could find with the Aeon was that the buckle on those slick super-thin straps tends to loosen easily. I was able to minimize this by doubling-back the tails of the straps through the buckle, but this is a place where Giro could spend a bit of time to make a functional improvement.

Conclusion
Though none of the Aeon’s features are really groundbreaking on their own, when combined they have produced a helmet that is exceedingly light, comfortable and ventilates well. There’s not a lot of drama because we’ve seen it all before, but the Aeon is a very solid, dependable helmet with performance that’s better than just about anything else out there.
