Giro Aries Spherical Helmet

PREMIUM LIGHTWEIGHT ROAD HELMET WITH SPHERICAL TECHNOLOGY POWERED BY MIPS, EXCEPTIONAL VENTILATION AND ADVANCED SWEAT MANAGEMENT.

The Giro Aries Spherical is a premium performance road helmet engineered to deliver exceptional cooling, low weight and advanced protection for demanding road cyclists.
Spherical Technology powered by Mips uses Giro's ball-and-socket design to help manage rotational forces during certain impacts, while Progressive Layering combines two different densities of EPS foam for more comprehensive energy management. Extensive Wind Tunnel ventilation, deep internal channeling and the Roc Loc 5+ Air fit system work together to maximise airflow, while Giro's DryCore system helps redirect sweat away from the rider's eyes.


KEY FEATURES

Spherical Technology Powered by Mips
Giro's Spherical Technology uses a ball-and-socket design powered by Mips, allowing the outer liner to rotate around the inner liner during certain impacts to help redirect rotational forces away from the brain.

Progressive Layering
Two different densities of EPS foam are used within the helmet to help manage energy across different impact speeds, providing a more comprehensive approach to impact protection.

Lightweight Performance
With a Manufacturer Claimed Weight of just 270 g in size Medium under CE certification, the Aries Spherical combines advanced protection and extensive ventilation in a remarkably lightweight package.

21 Wind Tunnel Vents
Giro's Wind Tunnel ventilation combines 21 active vents with internal exhaust channels to draw cool air over and around the head while helping expel heat and warm air.

Deep Internal Channeling
Intricately engineered internal channels work with the large ventilation openings to direct airflow across the scalp for exceptional cooling during hard efforts and warmer conditions.

Aura II Reinforcing Arch
The shatter-resistant Aura II Reinforcing Arch runs throughout the helmet to enhance structural integrity while allowing Giro to incorporate large ventilation openings for increased cooling.

Roc Loc 5+ Air Fit System
The Roc Loc 5+ Air system suspends the helmet slightly above the head, allowing cooling airflow to pass directly over the scalp. One-handed adjustment allows riders to fine-tune fit tension and fore-aft tilt.

DryCore Sweat Management
Giro's DryCore brow pad incorporates an internal silicone bead designed to redirect moisture away from the forehead, helping prevent sweat from running into the rider's eyes.

Eyewear Docking Ports
Integrated eyewear docking ports feature rubber grippers to help securely hold sunglasses when they're not being worn.

Ionic+ Padding
Ionic+ padding uses pure silver to provide permanent odour protection, helping keep the helmet feeling fresh through regular use.

Reflective Details
Reflective details help increase visibility in low-light conditions when illuminated by headlights or another light source.

SIZING

Small: 51-55 cm
Medium: 55-59 cm
Large: 59-63 cm
To determine your size, measure around the widest part of your head, keeping the measuring tape level from front to back. The helmet should fit securely with a small amount of room when the fit system is loose and sit low enough on the forehead to provide appropriate coverage without obstructing your vision.
