Advance Performance for the Adventurous
The heart of the Giro Helios' extraordinary design and performance is Spherical Technology, which utilizes a ball-and-socket design powered by MIPS the market-leading brain protection system that can help to reduce rotational forces.
Spherical Technology allows the helmet outer liner to rotate around the inner liner during a crash, and also allows Progressive Layering of the inner and outer liners to provide more comprehensive protection and performance. In addition to advanced head protection, the Helios 15 Wind Tunnel vents provide exceptional cooling power that's enhanced by the patented Roc Loc 5 Air fit system and plush, antimicrobial Ionic+ padding for exceptional sweat absorption.
It's the ideal match for your road and gravel adventures.
Features:
MIPS Spherical- Essentially an invisible low-friction layer sandwiched within two layers of EPS foam, the result is a reduction of rotational forces and the elimination of the plastic slip plane of the original MIPS design. Redirects impact energy by allowing the helmet's exterior liner to rotate independently of the interior liner in an angled impact.
Independent, In-Mold liners with Spherical ball-and-socket design
Polycarbonate shell
Hardbody lower shell
15 wind tunnel vents with internal channeling
Roc Loc 5 Air Fit System

Safe as the Aether but with a more comfortable Giro like fit
I really liked the protection and ventilation of my Giro Aether but I was never fond of the fit. I was on the largest size and it always felt a tiny bit too small, a different shape than my previous Giro helmets (Foray & Synthe) and it was constantly resting on my sunglasses. The new Helios is a bit lighter in the large size then my Aether and only just a little heavier than my non MIPS Synthe which is reasonable given the enhanced protection. On the ventilation side I haven't noticed much difference between the two but it's not gotten hot enough here to really tell, my guess is the Aether might be slighter better. On the general fit it's way better for me, no more sunglasses issue, a lot more comfortable especially on the 4+ hour rides. It also has the vertical adjustment on the Roc Loc which was missing on the Aether. Probably the only negative is it does not have the little sunglasses rest in the helmet but it still works fine you just need to be a bit more careful about placing them in enough.

Fits well, much cooler than my other helmet
I'm a fast recreational rider, 2-2.5K miles a year, typically ride in the A group. Was running an aero helmet, because I'm all about aero (even my water bottles are aero!) But on hot says I suffered way too much and it impacted my performance. This combined with having gone down a couple times last year meant I needed a cooler helmet and one that provided the best protection I could get. Can't train with a brain injury!
The Giro has proved to have much better with ventilation for those KOM efforts. And I feel better going all out when I know that I have the latest in protection.

A helmet that is at the Head of the Class.
Years of having what I would consider helmets has now been eclipsed by what is the very best helmet I have worn. Comfortable, adjustable and extremely light weight while still providing utmost protection. A perfect helmet!

Back to Giro
After many years of using a Catlike helmet, my wife returned to using Giro and the Giro Helios Spherical MIPS helmet didn't disappoint her as she really likes her new helmet. It is nice and lite. It fits really well. The adjustability is a simple dial in the back, making it easy when it is on her head.

Feels good and looks good
Got the white one, does the job. Hopefully I won't actually get to test out the power of the spherical technology and the MIPS system but it's comfortable, easy to adjust, feels like I'm wearing nothing that's how light it is and I'm comfortable knowing I have a premium protection system on my head.

Great Product. Great Price.
You can always expect to get great products at a great price from BikeTiresDirect. The Giro Helios helmet is fantastic. The design and color options great. This is my first helmet with MIPS. It's comforting to have the MIPS feature. I definitely recommend the helmet and definitely recommend purchasing from BikeTiresDirect with there awesome customer service and pricing.

Does the trick
My previous helmet was a Giro Aether - so comfortable and light. This is a touch heavier and covers more skull. I'm still getting used to it and wonder how long this break-in period will last.
