 The helmet, which was lighter than others at the time and featured filters to remove fumes and dust from the air, was taken by more drivers including then World Champion Michael Schumacher, and was gradually developed into the current RF1 model.Currently, Schuberth helmets are used by Max Verstappen, Fernando Alonso, Nico Hülkenberg, Felipe Massa, Nico Rosberg and Susie Wolff.Schuberth designs all current helmets in their own wind tunnel facilities, to enable maximum aerodynamic efficiency, and employed Michael Schumacher as a consultant for motorcycle helmet design.
