For those that need a little sensory deprevation, here is an inflatable, full-coverage hood with a breathing tube gag. It may be hard to really get an idea of the features of this item from the images, but we hope that they are somewhat helpful.

There are no eye openings and no nostril holes. The only opening is in the rubber gag on the inside of the hood. The gag is hollow in the center and is attached to the external breathing tube; great for those into various scenes.
