Details of the Giro Aries Spherical Bike Helmet

Its sleeker silhouette paired with a lighter weight (only 265 grams in size M) offers sensational comfort and cooling. Spherical Technology, based on the ball-and-socket principle, provides additional safety by reducing rotational forces generated in certain impact scenarios. Progressive layering with dual-layer Nanobead EPS foam of varying densities ensures even more comprehensive management of impact forces. The size of the 24 Wind-Tunnel™ vents is maximized by the integrated AURA reinforcement arch, while comfortable Ionic+ antimicrobial padding and a network of internal air channels optimize comfort. From the proven reliability and flexibility of the Roc Loc 5+ Air fit system, to the solid under-shell protection and meticulous build quality, the Aries is the epitome of top performance, safety, and style.
