Giro’s aero helmet is one of the most comfortable out there thanks to the easily adjusted Roc-Loc retention system, which holds it in place securely without the need to have the straps ridiculously tight, and a soft foam liner.
The side sections are ﬂexible so you don’t mash up your ears getting it on, and ﬁve vents up front funnel a generous helping of air inside, making it most suitable for warmer days.
The tail is short compared to, say, a Bell Meteor II’s, so check that it extends far enough back for your riding position.
That lack of length keeps the weight down; our medium model weighed just 340g. The Advantage conforms to all the usual safety standards and is available in several colour options.
