Neoprene is a brand name of polychloroprene, which is used as a substitute for rubber. Neoprene is entirely waterproof (this doesn’t mean you’re not going to get wet!), which makes it an ideal material for wetsuits and other gear designed to insulate against wet and cold environments. It helps people stay warm since the air pockets in the neoprene material hold water, which is quickly warmed by our skin, and continues to stay warm because of the heat from our bodies, the conductivity of water and the insulation of the fabric.
As well as that, neoprene is very physically resistant to cuts by abrasion, flexing and twisting! It also does not degrade in the presence of sun, ozone or weather and features excellent adhesion to fabrics and metals.
These all contribute towards a wetsuit being great for all cold Watersports adventures!
