What materials are drysuits made from?

Drysuits are made from a variety of materials that provide waterproofing, durability, and comfort. The choice of material often depends on the type of drysuit, the intended diving conditions, and the preferences of the diver. Here are some common materials used in the construction of drysuits:

Neoprene: Neoprene is a popular material used in drysuit construction, especially in neoprene and crushed neoprene drysuits. It is a type of synthetic rubber known for its insulating properties and flexibility. Neoprene drysuits provide both waterproofing and thermal protection in a single material. Crushed neoprene suits undergo a manufacturing process that compresses the neoprene, making it denser and more durable.
Trilaminate Fabric: Trilaminate drysuits are made from three layers of fabric: an outer shell, a middle waterproof layer (often a breathable membrane like Gore-Tex), and an inner lining. This construction offers durability, waterproofing, and the option to use different insulating undergarments.
Butyl Rubber: Butyl rubber is a synthetic rubber material used for its excellent gas impermeability, making it a good choice for maintaining a dry interior. Butyl rubber drysuits are known for their airtight properties and resistance to chemicals and gases.
Latex: Latex is commonly used for seals in drysuits, such as neck and wrist seals. It creates a tight, waterproof seal against the skin. However, some divers may be allergic to latex or find it less comfortable compared to other materials.
Polyurethane (PU) Coated Fabrics: PU-coated fabrics are often used in the construction of entry-level drysuits. They provide decent waterproofing and durability at a more affordable cost.
Cordura: Cordura is a durable fabric often used for reinforcement on high-wear areas of drysuits, such as the knees, elbows, and shoulders. It enhances the suit's overall durability and lifespan.
Kevlar: Kevlar is another high-strength fabric used for reinforcement, particularly in drysuits designed for more extreme conditions. It offers excellent abrasion resistance.
Breathable Membranes: Some drysuits, especially those intended for technical diving, use breathable membranes like Gore-Tex. These membranes allow moisture (sweat) to escape from the interior while preventing water from entering.
