A type of synthetic rubber that is extremely flexible and durable. Neoprene is used to make some sex toys and accessories, particularly accessories associated with BDSM (bondage, dominance, and submission).

Unlike some other rubbers, neoprene is made from tightly woven microfibers, and it cleans easily with soap and water. Neoprene allergies are very rare, but they can occur; common symptoms include redness, irritation, and itching.

Apart from sex toys and accessories, neoprene is used to make diving suits and sportswear.
