Details

From the top of the podium of the Tour de France, straight to your head comes Giro's Ionos. Built to the exacting demands of ProTour riders, the Ionos offers premium cooling, chic style and maximum protection. Giro's 21 massive Wind Tunnel vents keep you cool and dry, while the In-mold Composite Sub Frame provides massive amounts of protection when you need it most. Plus, the Ionos uses Giro's top-notch Roc Loc 4 system for a supremely comfortable and secure fit. And, this sweet lid is available in the colors of some of your favorite professional cycling teams.

How can the Ionos be so light and cool, and still meet the toughest safety standards? The secret is the use of a tough composite (the sections that look like white carbon in the photo). Giro calls this the In-mold Composite Sub Frame. It runs throughout the helmet liner and around the vents for incredible structural support, impact dispersion and resistance to penetration. It's also how the Ionos can have great big vents for amazing cooling and offer awesome protection, too.

    I've had my Ionos for a year and a half and love the fit and comfort. Vents are big and it comes with an inner for cold mornings. I crashed at 20+ MPH in the Manhattan Beach GP 2009 Cat 4 race and the helmet compressed at the back, so no concussion and felt very safe in it. I'll be buying another this week.

      Comments:

      I looked at several other helmets in this price range and they all felt flimsy and cheaply made to me. The Ionos feels very well-made and is lightweight, but does not feel quite as light as some of the alternatives. However, if you are not counting every gram and appreciate well-made stuff then I would recommend. The Ionos is very comfortable and very nicely finished inside and out - much less exposed foam than other helmets. The only downside I see is that the straps are not removable (like many other helmets now), so cleaning them will be a little more difficult. It is not a cheap helmet, but I feel like it is still a good value in a high-end helmet due to its design and build quality.

        OK -- I don't skimp on headgear, and this helmet was not cheap. Last weekend I crashed hard, hitting my head on a curb after my front tire flatted. The helmet absorbed the hit, buckling in three places. Yes, I had a concussion, but there is no doubt form those who saw what happened that I would not be writing this today had I not been wearing it. I will buy another.
