Creating a level of comfort never felt before, the Klim F4 Helmet, with an unprecedented 41 air-craving intakes, creates a new standard in helmet ventilation technology. It all starts with a design that more effectively channels air into the helmet where the EPS liner maximizes the airflow over the entire head to dramatically cool the rider’s head. Safety standards have been exceeded not only through the use of aerospace materials, but in the design of the helmet. The F4 exceeds Snell M2000, M2005 and U.S. DOT standards.
