Neoprene is a synthetic rubber originally developed in the 1930s, widely used in water sports gear and various everyday items due to its durability and flexibility. Scuba fabric, a fashion variant of neoprene, is made from polyester and lycra, known for its four-way stretch and suitability for form-fitting garments. While neoprene is better for active wear and water sports, scuba fabric is preferred for comfortable fashion applications, though it is generally less durable than neoprene.
