Aries Spherical Mips Helmet

What Our Gearhead® Experts Are Saying:

"I honestly forget I’m wearing this helmet once I’m rolling. It’s incredibly light, the airflow is next-level on hot climbs, and the Spherical Mips setup gives me confidence without adding bulk. This is my go-to for long, fast road days."

When comfort disappears and focus locks in, that’s when a helmet is doing its job—and the Aries Spherical Helmet excels at exactly that. Giro designed this helmet to feel almost invisible on the head, combining a sleek profile with exceptional cooling so we can push through long climbs and hot summer miles without distraction.

Spherical Technology powered by Mips works with Progressive Layering to manage both rotational forces and a wide range of impact energies, while 21 Wind Tunnel vents and deep internal channeling keep air moving continuously over the scalp. The DryCore brow pad redirects sweat before it becomes a problem, and the Roc Loc 5+ Air fit system fine-tunes stability while enhancing airflow. It’s a premium road helmet built for riders who demand top-tier protection without sacrificing comfort or speed.
