Why would I want a Full Face Mask? I already have a mask.

Until the SuperMask® was introduced, all full-face masks had one major drawback. If your regulator or gas supply failed, you had to remove the whole mask to gain access to an alternate source of breathing gas. With the Supermask®, switching to an alternate gas source is as simple as unlatching the pod from the mask and mounting another pod or simply using another second stage regulator. If your alternate air source is another SuperMask® pod, your communications will remain operable.
