Drysuit Fabric - Supplier

Our company produces neoprene drysuit fabrics by ourselves. YAMAMOTO #88 and Nam Liong DS high-density sponge are the most suitable fabrics. However, for cost considerations, the YAMAMOTO #50 #45 #39 and Nanliang F04 W7 W8 is also a frequently used model. The outer layer is usually compounded with small diamond fabric or nylon fabric, and the inner layer is compounded with nylon fabric.

Butyl tri-laminate fabric we use products from Taiwan or European manufacturers, and the outer layer has a variety of fabrics (nylon, polyester, Cordura and Kevlar) to choose from. The butyl tri-laminate fabric is durable, with high tear strength, soft hand, chemical resistance and water resistance. It is currently the mainstream material for drysuits.

Breathable tri-laminate fabric is a more popular material in recent years. The middle layer is usually a waterproof and breathable membrane material such as PU, PTFE, PU+PTFE, eVent, and the outer layer and inner layer are similar to butyl tri-laminate fabric. There are three-layer or four-layer structure due to different combinations of middle layers. It must be pointed out that the breathable tri-laminate used to make drysuits usually has a water pressure resistance index of 15000-20000 mmH2O, that is, it can only be used in shallow waters (≤10m) for diving applications. Drysuits made of this material take care of both water sports and diving.

Neoprene Drysuit Fabric

Neoprene Drysuit Fabric

Explain: We purchase high-density neoprene sponges (Japan-YAMAMOTO #88 / Taiwan-Nanliang DS) from Japan and Taiwan manufacturers, and self-processing. Sometimes due to cost considerations, regular types of neoprene (Taiwan-Nanliang F04 / W7 / F04) are also used.

Material: Outer layer - nylon fabric, small diamond fabric and Kevlar®, middle layer - neoprene rubber, inner layer - nylon fabric.

Note: Neoprene fabric is a traditional drysuit manufacturing material. It has good thermal insulation performance and simple production process, but it is relatively heavy and has a small market share at present.

Butyl Tri-Laminate Drysuit Fabric

Butyl Tri-Laminate Drysuit Fabric

Explain: We purchase butyl tri-laminate fabric from Taiwan or European manufacturers.

Material: Outer layer - nylon, polyester, Cordura®, Kevlar®, middle layer - butyl rubber, inner layer - 70D nylon or 75D polyester.

Note: Butyl tri-laminate fabric is currently the mainstream drysuit manufacturing material. It is lighter and more flexible than neoprene fabrics, but it does not have thermal insulation performance. When used in cold environments, it needs with a thermal undersuit.

Breathable Tri-Laminate Drysuit Fabric

Breathable Tri-Laminate Drysuit Fabric

Explain: We purchase breathable tri-laminate fabric from manufacturers in Japan, Taiwan and China. PU, PTFE, PU + PTFE are optional.

Material: Outer layer - 210D / 320D nylon or 330D Cordura®, middle layer - waterproof and breathable membrane, inner layer - 20D tricot.

Note: Breathable tri-laminate fabric is the first choice for surface drysuits and rescue drysuits, but it is not suitable for diving drysuits. Although many brands currently use it to make diving drysuit that can be carried easily in pursuit of lightness, but this is not a good choice.

Drysuit Type:

Type	Neoprene Drysuit	Butyl Drysuit	Breathable Drysuit
Material	Neoprene Fabric	Butyl Fabric	Breathable Fabric
Process	Glue & Blind Stitch + Glue Tape	Flatlock Stitch + Glue Tape	Flatlock Stitch + Hot Tape
Firmness	Good	Good	Ordinary
Easy to Carry	Not Good	Ordinary	Good
Thermal Insulation	Good	Little	Little
Valve	Inflation Valve, Exhaust Valve	Inflation Valve, Exhaust Valve	No or Dump Valve
Applications	Diving	Diving	Water Sports, Rescue

Note: Breathable tri-laminate drysuit are not suitable for diving, but because of its light and low-cost characteristics, many brands have launched ultra-lightweight travel drysuit (equipped with inflation valve and exhaust valve) made based on breathable tri-laminate fabric, but it can generally only be used for diving at a depth of no more than 10 meters. In fact, there are also lightweight options for butyl tri-laminate fabric, but the price is more expensive than breathable tri-laminate fabric.

Drysuits Leaking and Maintenance Problems:

All our drysuits are tested for pressure leaks in a test pool before leaving the factory to ensure that the drysuits do not leak when shipped, but the harsh transportation environment (Abnormal collision and squeezing) and incorrect storage (abnormal squeezes) occasionally cause water leaks (rarely found).

Unless drysuits are rarely used, water leakage is practically impossible to avoid. Due to the use environment, strength, habits, matching, cleaning and storage methods and occasions, component life and aging and other factors, many drysuits are used after dozens to hundreds of times, it will happen water leaks.

Leaking does not mean that drysuits can no longer be used, most of the water leakage conditions can be repaired. We provide warranty services (quality problems) and repair services (use problems). Unless the aging material has no repair value, everything else can be repaired.

Under normal circumstances, common simple problems are recommended to customers to repair by themselves (such as small leaks, etc.) to save time and transportation costs. We have optional repair kits when we leave the factory, and various repair kits are also available on the market. If there is a big problem, it is recommended that the customer return to the factory for repair (for example: replacing the waterproof zipper, repairing a large break, etc.).
