Mares Abyss 22 Extreme

This is the Abyss 22 plus Mares’ new Dry Cold Water Kit, which insulates the first stage and includes a coating for the second stage to prevent ice formation.

The first stage has a Tri-Material valve to enhance durability and includes a LP port called Dynamic Flow Control, which minimizes intermediate pressure drop during inhalation.

The second stage uses Mares’ VAD — a bypass tube that directs air to the mouthpiece and reduces inhalation resistance. In our tests this reg consistently performed above average. Divers found it to be dry and smooth in all positions, it cleared easily and bubble interference was minimal.

Bottom Line

This system delivers the goods and would be excellent for extreme temps, but it’s a little pricey.
