Lazer's O2 looks and feels great on all your riding adventures. It boasts in-mold construction for lightness and durability, as well as Lazer's easy-to-adjust Rollsys Retention System and a wicking Coolmax lining for a ride-all-day ease. You'll also appreciate the 24 large vents that keep you dry and ventilated on every ride.

The Rigidity Brace system is a reinforcement for a superior helmet resistance against multi impacts. This system is comparable with a roll cage in a racecar. In case of a crash, this will keep the cracked EPS pieces together so the helmet still offers some form of protection. This system does not guarantee the effectiveness of a helmet after a crash; every helmet needs to be inspected carefully after a crash and in case of dents or cracks it should be replaced. 

The main goal of wearing a helmet is to avoid getting injured. The fitting of a helmet is therefore very important and is essential for safety and comfort. As Lazer is always looking for innovation, we developed the most advanced fitting system to optimize comfort and fit. The Lazer Rollsys system is bornÖ

How does it work?

Compared to the standard fit systems, the Lazer Rollsys system is a fully integrated mechanism which surrounds the head completely. By turning a smooth thumb wheel (situated on top of the helmet rather than the back of the helmet) the Rollsys system permits an accurate and progressive peripheral sizing adjustment. The fit of the helmet will symmetrically be tightened without any pressure points on the head.

The Rollsys system offers an innovative one hand use and is easy to handle even during riding. By taking away the retention system at the back, the Rollsys system is also the perfect solution for people with a ponytail.

Roll into the Future

From the moment the Rollsys system was introduced to the market, it immediately got rewarded for its design and innovation. The testing by thousands of riders proved its efficiency and durability. In other wordsÖ plenty of reasons to integrate the Rollsys system in each newly developed helmet.

The adjustable head basket allows the back part of the rollsys system (that grips the back of the head) to move up and down depending on the riders preference. This way the Rollsys system can be adjusted even more to individual rider needs and can create even more comfort.

Coolmax is a high-tech padding solution that makes moisture disappear, dries quickly, and is breathable.

Sweating is one of the body's natural mechanisms to stay cool and with Coolmax it won't get annoying. Engineered with special technology to wick moisture and enhance drying, Coolmax fabric helps you stay dry and energized - exactly what you need to feel comfortable not only during the day, but also through your toughest workouts.

The Coolmax fabric is used in our helmet padding in order to provide you with a fresh and comfortable feeling throughout the ride.
