Giro Air Attack Helmet

 
Of course keeping cool is paramount with a closed in, aero lid and Giro are claiming enhanced airflow via their new ‘Roc Loc Air system’, which is designed to literally thrust air in through the front vents, over the head and out of the rear exhaust ports.

 
The shiny in-mould polycarbonate shell with protective EPS liner is combined with removable, washable, anti-microbial ‘X-Static comfort padding’, and fixes to your head via the ‘featherweight webbing with slimline buckle’ of Giro’s established Roc Loc system which is adjustable for tension around the head and for vertical positioning.
 

 
This particular variety, called Roc Loc Air, suspends the helmet, optimising the path of air over the rider’s head. Giro claim a Venturi effect implying that air is forced through the 6 vents and internal channeling to keep things cool.
 
Whilst Peter’s and Vince’s thoughts are illuminating, I haven’t ridden in the helmet yet myself but initial impressions are favourable next to my older Giro’s. On first inspection it is so shiny – you can see my reflection in every photo I took and I am not a good enough photographer to work out how to overcome that! – but the surface also scratches easily.
 
On trying the Air Attack on, it is easier to adjust and so much more comfortable than any of my other helmets. Importantly Giro have managed to make it feel much more secure as well, the new Roc Loc system eliminating any movement at all on vigorous head shaking compared to my vented lids.
 

 
As you can see from the photos, it’s noticeably smaller than a vented Giro helmet, an Ionos in this case, and weight wise there’s not much in it as the Air Attack comes in at 298g vs the Ionos at 319g. As we in the midst of a heatwave I will be able to test the comparative cooling between these lids immediately, though how I will measure any aero benefit I do not know…
 
Still it’s a good start for the Giro Air Attack, so check back for a full review soon.
