The Mountain High Constant Flow face mask is standard issue with all constant flow systems.
They are of the non-re-breathing type and calibrated for use with the MH-4 flow meter, or any other device calibrated to the standard protocol of 1 liter per minute, per 10,000 ft. per FAR 23.1447.
The XCR face mask has the 6mm outlet connector, as seen in the pictures.
