One of the things that I found incredibly useful during my time as a professional Dominatrix was the quickness and ease of a decent sensory deprivation hood. Sometimes I would have visitors who would enjoy nothing more than to be confined, shackled and deprived of their senses for hours at a time and with no other interaction. A hood gives a sense of confinement that a blindfold simply cannot.
The Uberkinky Fetish Fantasy Spandex Open Mouth Hood is a good beginner hood. Unlike a full leather construction, It allows basic shadows and movement to be seen through the material. Which is perfect for anyone who has difficulty with mild claustrophobia (while still wanting to undergo what their dominant wishes to put them through) or anyone who prefers to give their play partners a very small chance of ascertaining when the next strike will hit during play (sometimes little spoilers can be very fun).

One of the things to also take note of with this particular product is the material it is made from. Very stretchy and able to fit most head sizes but also of such a thin material that when ready to upgrade to a full leather hood, this one would make a very comfortable underlay.
What more can I say? Another groovy product from Uberkinky.
