Hex Helmet

The Hex fuses a muscular, progressive style with the versatility you need for aggressive trail riding. It's a great choice for price-conscious riders looking for a rugged all-mountain helmet that offers loads of premium features.

Wind Tunnel Ventilation

Giro helmets are developed utilizing our proprietary Wind Tunnel™ ventilation system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing heat and stale air out. It’s the most effective cooling system available, and a difference you can feel every time you ride.

Roc Loc 5 Fit System

The industry benchmark in comfort, stability, adjust ability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.

In-Mold Construction

In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.

How to Measure For Your Size:

To determine the correct helmet size, wrap a measuring tape around the head, keeping the tape just above the ears and level front to back. Once you've determined the measurement, you can use the chart here as a guide; however, we recommend that you try helmets on prior to purchase to ensure the best fit and comfort.
