Giro Aria Spherical Womens Helmet 2025

The all-in-one look

Seamlessly Integrated Shield
The seamlessly integrated VIVID shield aligns below the helmet brim, incorporating "Stack Vent" technology. It's been engineered to fit perfectly to your face to prevent wind and snow from entering the helmet while eliminating fogging.

Articulated Shield
The VIVID shield easily pulls out and over the helmet and back down. It sits securely on top of the helmet and provides a perfect fit on the face when in the down position.

MIPS Spherical
A reimagined version of the MIPS Brain Protection System that eliminates the plastic slip plane of the original MIPS design.

VIVID Lens Technology With Optics By ZEISS
VIVID is a patented lens technology - developed by Giro in partnership with ZEISS Optics - that improves the visual experience on snow by enhancing contrast and definition. VIVID Lens Technology effectively manipulates blue light by letting in contrast enhancing blue light, while blocking harmful UV light. Vivid essentially filters out the haze and frees your eyes to spot your line and focus on enjoying your riding experience.

In Form 2 Fit System
The In Form 2 Fit System is lighter and lower-profile than the original, and easier to dial in a custom fit in seconds - even with gloves on. An improved dial design provides up to 6cm of adjustment plus enhanced stability.

Thermostat Control
Thermostat Control Adjustable Venting allows you to custom-tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.
