After years of begging & pleading them for it, Giro has finally released an ANSI/Snell-approved full-on aerodynamic helmet, identical to what you see the ProTour TT gods use in the Tour de France. It's called the Advantage 2, and it's built with all the technical nous Giro brings to standard helmets like the Ionos and the Atmos. Companies such as Limar, Rudy Project, Specialized, and Louis Garneau have had aero helmets on the marketplace for awhile. But Giro is the Undisputed Heavyweight Champion of the helmet world, and most folks were keen to wait due to Giro's reputation for fit, weight, ventilation, and comfort. The wait was worthwhile.

The Advantage is available in 5 colors, in 3 sizes -- Small (51-55cm), Medium (55-59cm), and Large (>59cm). It's identical in shape to the Giro aero helmets you've seen top-notch pros ride TT's in for the last few years -- so you know it's aerodynamically dialed. But perhaps most amazing is its weight. It tips the scales at a mere 310g -- only 35g heavier than the madly popular Atmos helmet. If you were worried that wearing an aero helmet might be stifling or obnoxious in a hot summertime TT, you can dismiss your fears. The Advantage proved to be well worth the wait. The 5 vents and internal air channels keep you comfy, and the RocLoc2 retention system keeps it in place on your noggin.
