Giro Ionos Helmets

4.76/5 (21 Reviews)
MSRP : $230.00

Product Description

Giro Ionos Road Cycling Helmet is the most technologically advanced road cycling helmet Giro has ever created. The revolutionary in-mold composite sub-frame (I.C.S.) provides the strength support 21 of the largest vents ever carved into a helmet. These massived vents, coupled with an intricate network of internal exhaust ports, create a cooling system that Giro calls Wind Tunnel ventilation. Ionos keeps riders like Grand Tour Triple Crown Champion Alberto Contador cool and comfortable all season long.

Strengths:    Lightweight, strong, aerodynamic, comfortable, aesthetically pleasing

Weaknesses:    None

Bottom Line:   
This helmet is the best purchase I've ever made. Today, I was rounding a rotary at around 40-50 kph and braked suddenly for traffic. I lost control, did a 360+ degree front flip, and landed right on my helmet. It was a hard fall, definitely hard enough to crack my skull had I not been wearing my helmet. This helmet probably saved my life. Surprisingly, the helmet was undamaged. I bought it from eBay from China so it was super cheap too. It is so comfortable that you can barely feel it on your head.

Strengths:    Very good coverage. Excellent ventilation. Reasonabley light weight. Strong.

Weaknesses:    The Roc Loc with micro adjustment is fragile compared with older models. This doesn't compromise safety, but I have had to replace the system twice in two years. Replacement cost is about $12.

Bottom Line:   
Over the past 16 yeas I have averaged nearly 4,000 miles annually. A few days ago I experienced my second potentially serious crash. In my first crash I was wearing a Giro Atmos. This time, a Giro Ionos. I am alive to tell you that they both did their job. I feel very confident wtih Giro and especially the Ionos. It sits a bit lower on my head and provides excellent coverage. Last Sunday I was the victim of a hit and run. I was descending a long grade at 30 mph when a pickup pulled along side and then swerved into me with its front fender. I apparently landed and skidded on my helmet. It broke in several places but stayed intact. The impact was violent enough that a large portion of my head is bruised, but that means the helmet distributed the impact well. I'm alive and the hit and run driver was apprehended. I will replace my helmet with another Giro Ionos.

Strengths:    Very strong

Weaknesses:    None

Bottom Line:   
I cannot say one bad thing about the Ionos. I purchased the helmet in 2008 and it has treated me very well.

After a very nasty wipeout today, I can say the Ionos has lived up to the Giro reputation. Although the helmet is now completely damaged, it saved my life. I am looking forward to my next Giro purchase and expect the quality to match that of the Ionos. Hats off to Giro and the quality the bring to the table.

Thank you…

Strengths:    Weight is ok, venting is good and the fit really works for me. Looks are ok, fit is nice and easily adjustable.

Weaknesses:    A tad heavier than some others. Not as "pro" as some...

Bottom Line:   
I tried several helmets and ended up with this as it fit the best and did not interfere with my sunglasses. I also have a Xen for MTB and like the Giro fit for me. I tried a LAS and a Kask, both fit nice, the Kask was nice and low/snug but interfered with my sunglasses, the LAS did not vent as well because it had a full liner in it.

Strengths:    Durability
Easy to clean

Weaknesses:    None

Bottom Line:   
The Giro Ionos is simply the best! I rode close to 18,000 miles over the last 5 years and just had my first accident at 30+ mph. I woke up in the ambulance, after a concussion, CT scan confirmed internal bleeding which shortly went away. I didn't have any external injuries to the head. The Giro Ionos more than did its job. It split in 6 places yet remained intact! I've seen others come apart in crashes. So what's the verdict? I'm going shopping for my next Ionos. When your life is at stake, don't screw around, get the Ionos. You may pay a little more but isn't your life worth it?
