⭕ Kirby Morgan 37. I have had it from new, less than 19 months ago and it is an excellent hat. Never done any commercial, just private. It has new regulator, whiskers, face port, speakers and mic. It comes with the Black hat bag, Welding shield, extra oral nasal, and nose bar. This has been a great hat. Dial-a-breath functions flawlessly as well as the demand regulator. I have had zero problems with it. Nothing deep. May consider delivery too.
