Mares Abyss 22 Navy II scuba regulator is made for extreme conditions, and is the only regulator to pass the U.S. Navy's strict standards for extreme cold water diving. The Mares Abyss 22 Navy II Regulator is made to handle the most extreme conditions. This mares regulator is approved for use by the US Navy for extreme cold water diving. Made with a special fluoropolymer coating on the second stage, this prevents dirt particles and ice crystals from adhering - the Abyss 22 Navy II is virtually freeze-proof. The CWD kit provides protection against icing up during extreme cold water dives.


  • Dynamic Flow Control (DFC) minimizes pressure drop during inhalation
  • Tri-Material Valve to optimize performance, safety, and reliability
  • CWD kit and all key components of the second stage are coated with a flouropolymer resin finish
  • Better performance and reliability in extremely cold water, and even during ice diving
  • Vortex Assisted Design (VAD) provides a very sensitive and easy breathing at all depths
