Q: Why dive in a Drysuit?

A: Drysuits are very easily and quickly donned and removed. The warm and comfortable diver will be a clearer thinking one, & whose air consumption is likely to improve. Because the vital organs within the torso are warm, the extremities of hands and feet retain circulation and stay warmer. The Drysuit diver really scores on repeat dives when the suit is still just easily and quickly donned. The coldness encountered by wetsuit divers on repeat dives does not affect the Drysuit diver since the body’s core temperature of 37° C will not have been as affected by earlier dives as that of a wetsuit diver. The Drysuit diver has the added bonus that because the body is dry, of being far less affected by wind chill factors. Drysuits bring the pleasure back to Winter diving!

Q: Why should I buy an Oceandry Neoprene Drysuit?

A: We make our drysuits to a higher Commercial quality that makes them last so much longer than standard recreational drysuits. They are made from the best Yamamoto (Japan) neoprene, double Glued, stitched and fully hand taped on the inside seams, then extensively tested. We use quality neoprene rubber, layered with Titanium to retain warmth, covered externally with a tough wearing nylon (Kanoko), and plush lined on the inside.

Q: Why should I buy an Otter membrane Drysuit?

A: Otter make one of the very best membrane drysuits available and with there manufacturing methods it will ensure you have trouble free diving. Their drysuits are made with high quality materials that will last, all seams are double glued, double sewn and double taped to give you absolute confidence in any membrane drysuits weakest area of all the seams.             

Q: How do I decide between a Neoprene or Membrane drysuit.

A: A Neoprene drysuit uses the thickness of its material to retain warmth within the drysuit where a Membrane drysuit requires much warmer clothing to be worn as there is no thermal protection with its material. It is a personal choice, you need to decide if you want to dive in just the clothes you wear when on a diving trip that you can do with a neoprene drysuit, or dress-up with special undergarments for the membrane drysuits.

Q: What should I wear under a Neoprene drysuit.

A: In the warmer summer waters you can just have shorts and a tee shirt. In the colder winter waters a good track suit type clothing is okay.

Q: What should I wear under a membrane drysuit.

A: In the warmer summer waters you can wear normal warm clothing. In the colder winter waters a good undergarment is necessary and even thermals under this.

Q: What do I get with a new Oceandry drysuit.

A: The Drysuit, LP hose, zip lube, drysuit bag & an instruction booklet on how to use and maintain your drysuit.

Q: How long is the warrantee with Oceandry drysuits.

A: 2 years on workmanship and 12 months on individual components. We are one of the few companies in the world that give this same warrantee to recreational & Commercial divers. (Most drysuit companies have a no warrantee period if used commercially).

Q:  Yamamoto Neoprene 

HYPER-COMPRESSED Neoprene has been developed by YAMAMOTO, aiming at the most stringent demands of both DEEP SEA DIVERS and DRY SUIT PRODUCERS worldwide, aiming at creating the best compressed neoprene material yet available, with excellent eel! recovery and memory, with optimum resistance against deep water pressure compression, and at the same time maintaining that all important heat insulation factor and crucial body core thermal protection.

HYPER-COMPRESSED Neoprene is a "TRUE" Compressed Neoprene. Many of the "COMPRESSED" Neoprene materials and Dry Suits that are currently being offered on the market, are in fact made with HIGH DENSITY Neoprenes, which are not Compressed. They are merely stiffer more solid neoprene rubber compounds, which contain less amounts of Nitrogen Gas Cells, and therefore provide less Thermal Insulation.

YAMAMOTO HYPER-COMPRESSED is produced by expanding a Master Slab of regular dive grade Neoprene with 'Nitrogen Gas Closed Cells' up to 30mm thickness, and then COMPRESSING it in a heated pressure press back down to 15mm thickness. We then split the resulting Compressed Master Slab to the client's desired thicknesses. These split thicknesses in effect have double their thickness factor amount of thermal insulation.

YAMAMOTO's production method creates a true Compressed Neoprene which has an excellent compression resistance and memory/recovery, and at depths of around 40 meters a diver can really notice the difference in WARMTH & THERMAL PROTECTION, where other ordinary High Density Neoprenes are basically COLD ! HYPER-COMPRESSED is available in all thicknesses 2mm, 2.5mm, 3mm,3.5mm 4mm, 4.5mm, 5mm, etc, to clients preference.

HYPER-COMPRESSED can be lined with standard NYLON, or many of our specialized heavy duty fabrics, such as KANOKO 505, TECHNO 500, SPANDURA 800, all of which can be treated with our special PU Resin High Abrasion Resistant Coating CORALTEX I!, or lined using Yamamoto's superior TITANIUM ALPHA thermal coating.

Q: Why is Yamamoto Neoprene  the best

As a result of a series of diastrophism over a vast span of time beginning approximately 80 million years ago. a rock situated in the present-day Hawaiian Islands travelled a long way to Mt. Kurohime in Niigata. Prefecture, Japan. It was us, YAMAMOTO CORPORATION, who first shed light on this unique rock. Charmed by its mysteriousness, we have continued to create novel, business enterprises. Being composed of 99.7% calcium carbonate, this rock is miraculously free from almost all impurities. Using this rock as a starting material, we have developed a number of high-quality materials that have found applications in various fields such as; sports gear, medicine and fashion. Many of these have lead to the revolutionary new use of materials in these fields. Now, we have inspired yet another life into these rubber materials. In the evolution from technical rubber to Bio Rubber materials, our novel scope of activities has just begun.

We have been emphasising with our pride that YAMAMOTO Neoprene is not petrochemicals but is from Limestone base polymer with 99.7% calcium carbonate and this point also is emphasised for greater acceptance in the market of the medical products made of our neoprene rubber. It is not true that calcium carbonate foam is not as clean and environmentally friendly even from the point of its manufacturing process. We don't use at all the petroleum as the important resource. The quantity of heat for processing and producing our raw materials is merely one tenth of that being used for refining the petroleum and the used heat is used for the nursery of eels. The source of heat is from the used tires and the electric power is generated from the several dams and power stations constructed downward the high mountain range. This special technology to convert the limestone to the rubber is to be really environmentally clean and friendly.

In addition, as we informed, our YAMAMOTO Neoprene material is not petrochemicals but are from Limestone based on 99.7% calcium carbonate produced in the mountain for the cement materials. It reserve is estimated possibly available enough for next 3,000 years. Throughout the processing and production, only the hydro-electricity is employed, free from environmental pollution. The waste heat is made use for the nursery of eels.

The material can be processed, to its low viscosity at low temperature. It is precisely controlled at below 0.5 Centigrade. Special compound to match limestone.
The brief processing method of the limestone is to make acetylene gas spring up by burning the tire and to liquefy it by the chemical polymerisation, then to dry it to chips.

Japanese special technology to convert the limestone to the rubber is to protect the Earth environment.

Newly born production:
This new- wet & dry suit material which consists of a five(5)-later structure, neoprene rubber coated with Titanium Alloy and then laminated with synthetic fibre jerseys. As illustrated, the Titanium Alloy is a super thin film which provides effective heat retaining and heat retaining properties. In fact, a double lined material with Titanium Alloy will be 40% warmer than regular neoprene's. The stretchability, feeling and wear comfort remains the same as conventional materials. This makes it possible to use a reduced thickness of neoprene, for instance 3.0mm in lieu of 5.0mm, obtaining the same thermal protection. Thickness and weight reduced by 40% retains the same warmth. Because of its lower buoyancy, divers do not have to use so many weights and rivers with more safety. It is now possible to make sure of a lighter weight, with more comfort and ease of movement, providing the user with less fatigue and comfort. "This Hi-Tec composite material leads the way in this new century.
