We can only report Giro's claims and they say that the Air Attack has 11% less wind averaged aerodynamic drag that their Aeon. The main reason for buying the Air Attack is for the aerodynamic benefit but we simply have no way of measuring how it compares to the opposition on that front. Oh, and while we're mentioning weight, the Air Attack hit the Scales of Truth at 275g, which is pretty light seeing as a helmet with more holes than a Swiss cheese is doing well to get down to about 200g. Removable X-Static antibacterial padding inside adds to the comfort, as do the soft and lightweight webbing straps.
#GIRO AIRATTACK ROAD HELMET BLUE REVIEW TRIAL#
I've used a lot of different long-tailed time trial helmets for triathlon in the past and the Air Attack is better ventilated than any of them, and a lot more airy than anything that covers your ears. Or, at least, I didn't I know that other people are more sensitive on that front. You certainly don't feel like you're burning up in there. My perception wasn't quite that, but it wasn't a million miles off. Giro reckon that with its deep internal channelling the Air Attack has 97% of the cooling efficiency of their lightweight and well-vented Aeon helmet. I didn't find it uncomfortably hot and sweaty, just a little more so than normal. I started using the Air Attack a few weeks ago when the weather was quite a lot hotter than it is now – in the mid-20s – and conditions inside the helmet were a bit warmer and more humid than usual, but not nearly to the degree that I'd expected. What's different from Giro's standard Roc Loc System is that there's an inner cradle over your forehead and the top of your head as well, keeping the shell slightly raised to allow air to flow inside.Īs you'll have noticed, there are far fewer vents here than you find on most road helmets. Winding it up and letting out the slack are equally easily sorted with one hand. You get the choice of three height adjustment positions at the back and you control tightness with a clicky wheel. Giro reckon their system works for 98% of the population. The flexible plastic cradle attaches to the helmet shell at your temples so the helmet will fit the vast majority of people well.
The Air Attack fits like a standard road helmet using Giro's Roc Loc Air System. The Giro Air Attack has a similar overall profile to a standard road helmet but it's designed to be more aerodynamic to help you save time whether you're road riding, time trialling, or racing a triathlon.
