After the development of double-backed neoprene, singled-backed neoprene still had its uses for various specific purposes. For example, a thin strip of single-backed wrapped around the leg, neck, and wrist openings of the suit creates a seal that greatly reduces the flushing of water in and out of the suit as the person's body moves. But since the strip is very narrow, it does not drag on the skin of the wearer and thus makes the suit easy to put on and remove. The strip can also be fitted with the smooth side out and folded under to form a seal with a small length of smooth surface against the skin.
