Giro Helios Spherical Road Cycling Helmet - White/Silver

Season:SP25

Brand:Giro

Code:34671-548

The Giro Helios Spherical Cycling Helmet is engineered for high-performance road cyclists, gravel riders, and adventure enthusiasts. Combining cutting-edge safety technology with superior ventilation and comfort, this helmet delivers the ultimate riding experience.

Advanced Protection with Spherical Technology & Mips®

At the core of the Helios Spherical is Spherical Technology, a revolutionary ball-and-socket design powered by Mips®, the industry-leading brain protection system. This design allows the outer shell to rotate around the inner liner upon impact, helping to redirect rotational forces away from the brain.

Additionally, Progressive Layering™ technology features two different-density EPS foam liners to absorb both high- and low-speed impacts for comprehensive protection.

Superior Comfort & Ventilation

15 Wind Tunnel Vents & Internal Channeling: Designed for maximum airflow, these vents work with internal channels to push cool air across your scalp while efficiently exhausting heat.

Roc Loc® 5 Air Fit System: Enhances fit, comfort, and stability, while also improving ventilation by suspending the helmet slightly above the head. Easily adjust the fit with one hand.

Ionic+® Antimicrobial Padding: Infused with pure silver, this padding provides permanent odour control and superior sweat absorption to keep your helmet fresh.

  • Best-in-class safety with Mips® brain protection system
  • Lightweight and aerodynamic design for optimal performance
  • Advanced cooling system for superior comfort on long rides
  • Perfect for road cycling, gravel riding, and endurance adventures

The Giro Helios Spherical Helmet is engineered for speed, safety, and superior comfort.

Sizing Information

These size charts and conversions are meant to serve as a guide. Giro recommend you try-on before riding to ensure full comfort and performance.

Bike Helmet Size Guide

How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

For helmets equipped with MIPS technology, please review the following warning: SOME MIPS® LOW-FRICTION LAYERS, ALONG WITH OTHER PARTS OF A HELMET, MIGHT CAUSE LACERATIONS TO THE WEARER’S HEAD/FACE IN SOME ACCIDENTS. THIS MIGHT OCCUR DUE TO THE HIGH PRESSURE ON THE SCALP FROM THE IMPACT OR AS A BY-PRODUCT OF THE LOW-FRICTION LAYER’S MOVEMENT IN CERTAIN ANGLED IMPACTS TO HELP REDUCE THE ROTATIONAL ENERGIES TO THE HEAD. IF YOU WOULD LIKE FURTHER INFORMATION, PLEASE CONTACT US.
