How do you make the best better? That’s the challenge our designers and engineers faced when creating the successor to the Aether. And with the Aries Spherical, they’ve truly outdone themselves. Lighter, cooler, faster – and all in a smaller,
sleeker form that is both fresh and clearly a Giro design. It’s our most premium helmet ever and a true object of desire. From Pro Tour professionals to riders breaking away on epic gravel adventures, Aries Spherical is the helmet everyone is going to want.

A helmet that feels like it isn’t there: the all-new Aries Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology our ball-and-socket design powered by Mips adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is the epitome of top-shelf performance, protection, and style.
