Great value

Bought this as a summer helmet. Size, fit and quality can't be faulted in any way.

Detailed product description


X-static Padding:
Besides being comfortable, the X-static pads have anti-microbial properties meaning your helmet stays clean for longer. The pads are machine washable.

In-Mold Construction:
The In-Mold Construction combines a strong poly-carbonate outer shell with
shock absorbing helmet padding. The Fusion-process allows for optimal ventilation and creates lighter and cooler helmets than old, traditional helmets.

Wind Tunnel Ventilation:
Giro helmets are developed using its Giro Wind Tunnel ventilation system. This system combines the active vents with the internal ventilation outlets. This combination ensures a cool, fresh air flow over and around the riders head, while forcing the heat and stale air out. The redesign of these ''air channels'' turns out to be a huge success. The riders were really enthusiastic, they noticed the new ''air flow'' around their head, resulting in improved cooling!

POV Vizier:
Point of View visors are anchored by a patented and internal connection mechanism. The visor is up to 15° adjustable without any tools and can be adjusted up- or downwards. The visor is designed to stay in place and prevents loosening and rattling, even through rough terrain.

Roc Loc 5:
After more than two years of development, Giro introduces Roc Loc 5. This groundbreaking fit system provides an entirely unique user experience. It has an unmatched level of comfort, stability, adjustability and weight saving. With Roc Loc 5, you can adjust the fit, tension, and vertical position with one hand. The weight of the Roc Loc 5 has been reduced by almost 40% compared to its predecessor!
