Mares 25X First Stage - XR Line

Sold out

The 25XR first stage is extremely reliable and perfectly sealed thanks to the standard CWD kit. Perfect for any type of configuration with pre-oriented HP outputs.
The 25XR AST first stage was created to mainly meet the needs of divers using the double tank or to be mounted on a stage.
