Neoprene (device)

A stretchy, non breathing fabric used in a variety of horse-related products. It is flexible, waterproof, and airtight and can be molded to various parts of the horse's anatomy.

It is often used to wrap tails, as it grips well and doesn't slip off, and for protective boots and neck sweats.

It's important to use moderate tension when wrapping neoprene, however, as it can easily be put on too tightly, thus cutting off circulation.
