What is the difference between rubber and neoprene? Rubber is ideal for use in cold water/winter conditions due to its ability to shield the wearer from wind chill and lock in needed body heat. Rubber is not as durable as neoprene, so it is more vulnerable to hazards such as rocks, fingernails, fins, etc. Neoprene tends to age better against wear and tear and is available in a variety of colors, whereas rubber only comes in black.
