• Classic downstream valve.
  Classic downstream valves are particularly noted for safety and reliability. When in use, the downstream valve opens in the same direction as the incoming airflow. To close the valve and stop the airflow, a spring counteracts the force of the incoming air.
• Venturi Initiated Vacuum Assist (VIVA).
  VIVA uses the power of a vacuum assist to reduce work of breathing and increase breathing comfort. It is diver adjustable. A VIVA in MAX position gives powerful breathing support on every single breath; a VIVA in MIN position helps to prevent free flow on the surface, for training, for buddy breathing, in currents, or when used as an octopus.
• Orthodontic mouthpiece.SUBGEAR uses a comfortable orthodontic mouthpiece; only a minimum effort is needed to hold it comfortably in place.
