LAZER O2 CE Helmet - White

Ready when you are, whether it's a commute, sportive or you're attaching an aero shell and sprinting for the win, the O2 helmet is ready for it.
Compact profile, light weight, well vented, and a great fit, all the features of a helmet twice its price with added reflective panels for rear visibility. Added reflective material has been fitted around the helmet to increase visibility.
Rollsys is Lazer's very own award winning fit system: simply control the size and the comfort by turning the wheel on the top of the helmet. The Rollsys system permits an accurate and progressive peripheral sizing adjustment. The fit of the helmet will be symmetrically tightened up without any pressure points on the head, with a simple one-handed adjustment.
By taking away the retention system at the back the Rollsys system is also the perfect solution for people with a ponytail. A small light can also be purchased separately to add you your Rollsys to increase your visibility. Aero shells can also be bough separately.
