Neoprene serves as the core material, providing excellent thermal insulation. It keeps divers warm in the often cold underwater environment, allowing them to explore for extended periods without discomfort from the chill. The fabric combined with it enhances the suit's durability and flexibility. It can withstand the abrasion from contact with rocks, coral reefs, and other elements underwater, while also ensuring that divers can move freely and naturally as they swim and maneuver.
