Premium Ultralight Climbing Helmet! The use of an expanded polypropylene (EPP) shell and a minimalist fit system results in extremely low weight. In addition to the impressive cushioning performance of EPP, the helmet shell is reinforced with a robust outer layer ensuring optimal safety. To allow the climber to keep his cool for the next key passage, the Wall Rider has a multitude of large ventilation openings. The ergonomics and the customizable fit system of the helmet guarantee a perfect fit on the skull. Two clips and a rubber tab also allow you to attach a headlamp to the helmet.
