We always use high-quality material to deliver suits that will be warm, comfortable and durable. All of our suits are made of neoprene, which is a type of rubber that acts as an insulator to prevent thermal diffusion. Neoprene is usually laminated on one or both sides with different types of material, depending on what use the suit is designed for. Stretchier, more flexible materials are desirable for surfing, and thicker, more compression-resistant materials are used for diving suits.
