Giro Aries Spherical Road Helmet
With the Aries Spherical, Giro has managed to make their best road cycling helmet even better. The Giro Aries is faster, lighter and cooler than its predecessor, the Aether, and has a smaller, sleeker form. The brand's most premium offering to date, this helmet incorporates a number of advanced performance technologies and delivers outstanding comfort.
Aries Spherical Helmet Technology
Giro's Spherical Technology™ uses a ball-and-socket design and is powered by Mips® to create the ultimate protection if impact occurs, redirecting energy away from the brain, significantly reducing the chance of mild and more serious brain injuries. This technology is sandwiched between dual density Nanobead EPS foam in a Progressive Layering design to further manage impact energy.
Keep Cool with the Giro Aries Helmet
24 Wind Tunnel vents, deep internal channelling, and an AURA II Reinforcement Arch maximise the cooling effect, keeping the rider as fresh as possible on the hottest days and through the hardest efforts. Ionic+ inner padding is anti-microbial to prevent the build-up of bad smells over time, while the inclusion of a plush DryCore™ brow pad stops sweat from running into the eyes or down the face.
The Giro Aries Spherical use of a Roc Loc® Air fit system provides the rider with the assurance of a secure and comfortable fit that offers plenty of room for micro-adjustment.
