This is a Commercial Diver's Full Face
Scuba Mask. It's brand New and
probably most important: It's Black
Silicone. Not rubber that will
deteriorate after a short time. It'll
also fit better because of the more
pliable silicone. You'll have no jaw
fatigue with this mask. The mask
supports the weight of the regulator.
Just remove your regulator mouthpiece
and place into mask.
