The REX® regulator is a balanced, all stainless steel regulator designed for maximum breathing performance with minimum supply pressures and is currently available on the KM-47 and KM-77 helmets only.
The EXO® 26 Standard Full Face Mask utilizes an external high impact plastic frame known as an EXO® Skeleton mated to one piece face seal in a trampoline fashion making the mask exceptionally comfortable and strong.
The EXO® BR (Balanced Regulator)is virtually identical to the EXO standard and with the only difference being that the demand regulator is of a balanced inlet valve design that offers the greatest breathing performance of any full face mask.
