Giro Aries Spherical Bike Helmet -Matte White - Medium | Barely-there feel and elite protection define the Aries Spherical Helmet

AURA II REINFORCING ARCH — The shatter-resistant and translucent Aura II Reinforcing Arch runs throughout the helmet, bolstering structural integrity and allowing massive vents for cooling

DRYCORE — The DryCore sweat management system utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes.

SPHERICAL TECHNOLOGY — Spherical Technology's Ball-and-Socket design, powered by Mips, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.

INTEGRATED MIPS BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system.

21 WIND TUNNEL VENTS — Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust cool, fresh air over and around the rider's head while forcing heat and stale air out.
