Neoprene Drysuit - Manufacturer and Supplier

Neoprene is a traditional drysuit manufacturing material. Special models of high-density neoprene (Japan-YAMAMOTO #88 / Taiwan-Nam Liong DS) are usually used. Sometimes due to cost considerations, standard neoprene (Taiwan-Nam Liong F04 / W7 / W8) is also used. The standard neoprene has low density, large buoyancy, and poor compression resistance. The drysuit made is slightly inferior in performance, but lower in cost.

The neoprene drysuit is soft and flexible, has good thermal performance, and is durable. The disadvantage is that it is bulky, has a certain buoyancy, is greatly affected by compression (Especially when using standard neoprene), and has a longer drying time. Neoprene drysuits are mainly used in cold waters and are not suitable for warm environments.

Neoprene drysuits optional back zipper or front diagonal zipper, equipped with inflation valve and exhaust valve, heavy vulcanized rubber boots, neck and wrists use seals to prevent water ingress (Commonly available are smooth skin seals and latex seals. The smooth skin seals have a longer service life, but less elasticity. The latex seals are soft and can be adjusted for cutting, but need to be replaced regularly.).

Seam Construction

GBS: After the two pieces neoprene fabric are bonded with "Glue", the seam is then sewed with "Blind Stitch" process.

Weld: After the two pieces neoprene fabric are bonded with "Glue", the two sides of the seam is then reinforced with "Tape" / "Liquid" / "Neotape".

Seam Reinforcement

Tape Seam: Using fabric as a substrate, bonded by hot melt adhesive film, thin, the cost is relatively cheap.

Liquid Seam: Using liquid rubber as a substrate, forming a protective tape after curing, has smooth surface, and waterproof performance is the best.

Neotape Seam: Using CR neoprene as a substrate, bonded by glue, has better elasticity, firmness and waterproof performance, but the cost is relatively higher.

High Density Neoprene for Drysuit:

Type Elongation Rate (%) Density (g/cm3) Hardness (Type C)
DS 300 0.30 15-20
#88 312 0.36 15-20

Remark: This is a high density neoprene for drysuits. It is a special high-strength material made by special compression directly in the sponge production process to increase the density of neoprene. Low buoyancy, high compression resistance, but expensive, suitable for professional and extreme fields.

Standard Neoprene for Drysuit:

Type Elongation Rate (%) Density (g/cm3) Hardness (Type C)
W8 450 0.18 3-5
W7 500 0.18 5-7
F04 450 0.20 9-11

Remark: This is a standard neoprene. It is mainly used to make wetsuits, the price is relatively cheap. The drysuits made of this material have slightly lower performance and are mainly used in general fields.

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

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.).
