In memory of Ken Block, we are honored to introduce the Altitude 2.0 Helmet by Ken Block, with a percentage of the helmet's proceeds going to the Ken Block Foundation, 43i Institute, this helmet is all about carrying on Ken Block’s greatest legacy: creating paths of opportunity for the exceptionally driven who may lack the proper support system for growth and success. Just as Ken did, the 509 Altitude 2.0 Helmet excels in any terrain or condition. Including the Fidlock magnetic strap buckle for easy one-handed operation, lightweight and strong hand lay-up fiberglass construction, and customizable features like a removable Pro-Series Breath box to get you through a full season of extremes. DOT approved. Meets the FMVSS 218 Standard.
