A bondage hood is a type of fabric mask used in BDSM (Bondage and Discipline, Dominance and Submission, Sadism and Masochism) activities. It is usually made of leather or latex, and covers the head and face of the wearer. The hood can be used to blindfold the wearer, keeping them in the dark, or it may be used as an element of dominance, with the wearer not knowing what their partner is about to do next. It can also be used for sensation play, with the wearer experiencing different types of sensations that can be pleasurable or intense.
