Neoprene & Membrane Drysuit - Manufacturer and Supplier

Our dive drysuits are manufactured from neoprene fabric or butyl tri-laminate fabric, and rescue drysuits are made of breathable tri-laminate fabric. We have been providing high-quality OEM and ODM services to many well-known brands for a long time. We also provide related products to the Navy and Fire Rescue Department. Now we also accept small batch orders and provide customized services.

Neoprene drysuits are durable, easy to repair, have good elasticity and warmth, but are bulky and suitable for low temperature cold water environments. The butyl drysuits is light and flexible, but relatively fragile, difficult to repair, and has relatively poor thermal insulation performance. It is suitable for relatively high temperature environments. The rescue breathable drysuit is mainly used for flood and marine rescue missions. The membrane drysuits has almost no insulation performance, and usually needs to be paired with a thermal undersuits when used in cold waters.

Neoprene Drysuit

Explain: 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.

Note: 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.

Butyl Tri-Laminate Drysuit

Explain: Butyl tri-laminate fabric is a light and strong material. It is currently the mainstream material for drysuits. drysuit of this material are mainly used for diving, but its thermal insulation performance is not as good as that of neoprene drysuits. It needs to be used with thermal undersuits. It is not stretch, the drysuit made are usually loose and easy to put on and take off.

Note: We use butyl tri-laminate fabric from Taiwan or European manufacturers to make drysuits. In response to the current market demand, we can provide ultra-lightweight butyl tri-laminate fabric to make divsuits (the whole drysuits are controlled below 3KG).

Breathable Tri-Laminate Drysuit

Explain: Breathable tri-laminate fabric is a material that allows the body to get rid of moisture, but it also has a certain waterproof performance. Allows the wearer to keep the body dry in a humid environment. It is mainly used to make amphibious drysuits that take into account the diving performance, surface drysuits (surfing, kayaking, canoeing, sailing, boating, etc.) and rescue drysuits.

Note: We use breathable tri-laminate fabric produced by Japan, Taiwan and China manufacturers to make drysuit for various purposes. Breathable tri-laminate fabric due to the limitation of its own material (the middle layer membrane), PU film is prone to yellowing and cracking, PTFE film is easy to layer, and is not resistant to folding, so its durability is not as good as that of butyl tri-laminate fabric. The recommended service life is 1 - 2 years (depending on different materials).

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.).
