The "NEPTUNE" model EXP-100 Tailored Drysuit made by KME Diving Suits, Inc. meets or exceeds the highest standards for materials and craftsmanship for drysuits in the diving industry.

The EXP-100's Tailored fit and Guaranteed dry seams insure the most warm and comfortable cold water diving possible.

The EXP-100 Tailored drysuit is made of the best grade of neoprene diving suit material available. The water and gas tight (guaranteed to one atmosphere pressure differential) shoulder entry zipper in the EXP-100 is a Heavy Duty "BDM" model 6-RS. An Optional "Comfort" or "Relief" zipper (standard size) is available. It is usually placed horizontally, just above the crotch.

The standard boot on the EXP-100 is the KME "Deck Boot". The Deck Boot is a neoprene sock with a heavy solid rubber sole, hand lasted in place. Optional is the light-weight "Turbo" sole boot or an upgrade to the molded "K-Boot". Neoprene sock feet are another Option.

The EXP-100 Knee Pads are drysuit material with a reinforced coating, and are double sewn to the legs so that they may be replaced if necessary. Knee pads with "Ballistic" nylon over the neoprene cover are Optional.

All KME Drysuits have the optional choice of "Trident" commercial rated manual buoyancy control valves or "Si Tech" adjustable "automatic" exhaust valves at no difference in price. The "Trident" D model valves have a one year warranty and they are serviceable and repairable with replacement parts available at KME Dealers or the factory.

An American style standard fittings, 31 inch long, Low Pressure Inflation Valve Air Supply Hose, or L.P. Hose comes with the EXP-100. Other drysuit inflation systems, (Oral or Power/Oral inflators) are Optional.

All adhesives used in the manufacturing of the EXP-100 are the best available in North America for each bonding need. Four different types of adhesives are used in assembling every KME Drysuit.

Each EXP-100 Drysuit ordered has a matching hood, making each NEPTUNE series drysuit a complete "ready to dive" suit.

Many Options are available for all KME Drysuits, such as Attached Hood, Butt, Shoulder and Elbow Pads, Special Pockets; Knife Pockets, Comfort Zippers, other Access Zippers, P Valves, and many more.

Each Drysuit in KME's NEPTUNE series is Tailored, using our exclusive measuring system. (Stock sized NEPTUNE Drysuit models may be ordered, with a $ 25.00 discount per suit). The diver has a choice of Snug (like a loose fitting wet suit), Regular (oversized just enough to wear street clothes with light underwear and a light sweater) or Loose (heavy "pile" underwear or bulky clothing).

KME begins each Tailored NEPTUNE Drysuit by making a pattern, using the customer's measurements, on a sheet of heavy paper. This is then cut out to use as the suit pattern. After marking the material then cutting the drysuit components out, this pattern is filed away in case the customer needs another suit in the future. KME uses a power "rotary shear" type cutter to assure that all cuts are clean and perpendicular to the sheet in order to make the best glue joints possible. All glue joints are triple glued with a neoprene cement that is expressly designed for gluing drysuits. Zippers are "sandwiched" between neoprene panels in order to make a matching "butt" joint with the rest of the dry suit. Usually all outside seams are sewn, using a "blind stitch" sewing machine. This "blind stitch" machine, a special sewing machine for diving suits, sews across the seams only penetrating the top nylon layer. Next, the seams on the inside of the drysuit are sealed by KME's proprietary "TCV" Seam Sealing process. The last manufacturing step is installation of the valve system. Finally, the drysuit is inspected and prepared for shipment.

Taped outer seams are an Option.

(The Optional seam tape on the outside seams to make your drysuit petroleum proof and resistant to most other chemicals you are likely to encounter in the water, is available in place of sewing on the outside of KME Drysuits)

EXP-600-T: Deluxe technical dry suit with heavy duty back entry zipper and super heavy weave exterior nylon

The EXP-600-T Technical Diving Dry Suit is the wreck diving, deep diving or cave diving version of the NEPTUNE Series Tailored Dry Suit and is based on the EXP-100.

The EXP-600-T Technical Dry Suit is made from special Super Heavy Weave nylon fabric laminated on the outside of rugged drysuit grade neoprene foam sheet, with standard 4 way stretch nylon on the inside.  The standard thickness of this drysuit is 1/8" (3 mm), but other thicknesses are available on order.

The back shoulder-entry zipper used in the EXP-600-T is a Heavy Duty (size #6) gas and water tight zipper made only by "BDM" in England.

The standard boot on the EXP-600-T is the K-Boot, an outer molded rubber shell with a water tight neoprene foam "sock" bonded inside, then joined to the dry suit leg. The K-Boot is designed for swim fin use. The K-Boot is available in sizes from # 4 to # 14, with no half sizes. Other KME boots are available as Options.

The Air Control Valves on this dry suit are TRIDENT™ (commercial grade) dry suit valves. The TRIDENT exhaust valve is manually operated and is designed to not let water into the suit when the operating button is depressed.

For the diver that wants an adjustable self venting exhaust valve, KME offers the SITECH TM low profile model. The diver has their choice of valve placement in all KME dry suits.

All adhesives (four different) used in the EXP-600-T are the best available for
each use. NO wetsuit grade glues are used. The seams are triple glued, primed then hot taped on the outside, and then they are hand sealed on the inside with KME's exclusive TCV system.

Neptune EXP-600 and 600-T, Front and Back

EXP-200: Deluxe dry suit with standard American made (YKK) back shoulder entry zipper

The EXP-200 is exactly the same as the EXP-100 with the exception of the drysuit waterproof entry zipper. The zipper in the EXP-200 is a standard size (#8) American-made waterproof zipper from YKK, USA (The EXP-100 uses a heavy duty zipper.)

EXP-222: Surface water sports suit

The EXP-222 water sport drysuit is the same design and is made from the same quality materials as the other suits in the NEPTUNE series. The difference is the absence of drysuit valves. This rugged, form-fitting, flexible and stretchable exposure suit is ideal for sailing, wind surfing, surfing, jet- and water-skiing, and many other "on- or in-the-water" non-diving uses.


The EXP-222 drysuit is made of the best materials available. The body of the drysuit is made from drysuit grade sheet foam neoprene material with Jersey knit stretch nylon on both sides. You have the choice of suit thickness to meet your needs, ranging from 1/8" (3 mm), 3/16" (5 mm) or 1/4" (6.5 mm) at no additional cost.

The waterproof zipper used by KME in the EXP-222 is a diving drysuit standard size 8 TZ gas and is water tight to 1 atmosphere. An optional "relief" zipper positioned horizontally in front, just above the crotch is also available. As an option, KME will install a "BDM" Heavy Duty waterproof zipper for the shoulder entry zipper, in place of the size 8 TZ Standard zipper.

The standard boot on the EXP-222 is the "TURBO-Boot" manufactured by KME, using a rubber sole lasted on a waterproof neoprene sock. Other optional boots are available, with the upgrade to the "K-Boot", being the most popular. The K-Boot fits well inside swim fins or heavy overshoes and it is petroleum proof.

All adhesives used in the EXP-222 are the best available for each functional use, no "wet suit" adhesives are used. The drysuit seams are sewn with nylon thread on the outside or, as an option, a nylon sealing tape . All suits are sealed over the inside seams with a replaceable and repairable rubber compound.

KME makes two industrial grades of the EXP-222 dry suit. For specific information on these dry suits, contact KME for further information.

KME makes available a full line of Drysuit maintenance and repair products, so that field repairs may be made by the user. KME does repairs, alterations or parts replacement on all brands and types of drysuits, wet suits, survival suits and fishing waders.

EXP-300: Self-donning "around the body" entry zipper dry suit

This Self Donning Drysuit features a Special waterproof zipper with curves built into it in the the underarm area to eliminate damaging "twist" that occurs when a standard drysuit waterproof zipper is used in this type of self donning configuration. KME custom vulcanizes the curves into the zippers in our plant to fit the Tailored suit patterns.

The EXP-300 NEPTUNE model Tailored Self Donning drysuit is fabricated from the best neoprene available with nylon fabric on both sides. Standard suit is 1/4" thick. Other thickness' as well as grades of nylon and color available.


PISCES SERIES: Our stock size dry suit


EXP-500-DV: Stock dry suit with customizing as an option

EXP seam reduction engineering eliminates vulnerable crotch seams and failure prone four corner seams in critical areas. These are the same patterns that are the starting base for our Neptune model series Tailored Drysuits. All KME's seams are triple glued using modern adhesives made specifically for neoprene dyrsuit construction. The seams are then "blind stitched" (sewn horizontally across the seam, catching the nylon, but not penetrating through the neoprene) on the outside of the drysuit. Next, KME,s unique "TVC" Seam Sealing process seals ALL seams on the inside of each drysuit, allowing KME to offer GUARANTEED DRY SEAMS.

PISCES Series Drysuits have YKK standard size waterproof zippers placed in the shoulder entry position across the back. An Optional "Comfort" zipper is available, along with all the other OPTIONS available on all other KME Drysuits. The boots on the PISCES Series Drysuits are the lightweight "TURBO" type, but Upgrades are Optional and available on order. "Customizing" is an Option on the PISCES.

KME uses female patterns and sizing for the lady divers, we do not alter the smaller male sizes and hope for an acceptable fit.

KME uses the best drysuit grade of "Off-shore" made neoprene to produce this line of drysuits. We make them in our factory in the USA, using as many American made components as possible.

More information is available by e-mail on all our PISCES models (EXP-500-DV, EXP-500, EXP-550-DV, EXP-550).

A short history of diving drysuits

Shell Drysuits

Shell drysuits are defined as any diving suit that keeps the diver from getting wet by a means of a thin waterproof membrane material. The membrane can be single or a composite.

The first drysuits were developed in England in the early 1800's to work with the newly developed miner's copper fire fighting helmet invented by Dean, to allow it to be used underwater. In fact the first models were simple open bottom skirts, attached to the copper hat's "breast plate" by rivets and waterproofed by tar. Thereafter the term "dress" has since been applied to the copper helmet "hard hat" or "deep sea" drysuits. These first drysuits were at first made of tarred cotton fabric, but shortly a method of coating natural rubber between two layers of cotton twill was devised. Dresses were made this way until 1964 for the Navy MK-V gear.

Shortly before Word War II, both England and Italy developed drysuits made of sheet vulcanized rubber for their "frogmen" diver swimmers. These dry suits were donned through a front or back "tunnel".

After WW II, a rubber company in Norway developed a drysuit made of rubber laminated onto a lightweight fabric for hard hat divers. This suit later developed into the "Viking" brand drysuits.

Shortly thereafter a Japanese company upgraded their cotton-rubber-cotton type dresses to nylon-rubber-nylon, which made a very durable hard hat dress for working divers.

About 25 years ago an English firm developed a method of bonding a thick enough polyurethane film to one side of nylon fabric to make it waterproof ("Pack Cloth"). They also developed a tape film that could be hot air welded over the sewn seams, sealing them to fabricate a drysuit.

The latest type shell drysuit is a "re-invention of the wheel" type material known as tri-laminate. This "Tri-lam" uses modern materials, such as nylon or polyester fabric with a modern synthetic rubber, as a water proof barrier between two sheets of fabric, the same way the first drysuit (diving dress) material was fabricated in the 1800s.

Neoprene Drysuits

In WWII, while plans were being made for the invasion of Normandy, the Navy found that their beach clearance "Frog men" UDT divers would need thermal protection in the cold waters of the English Channel. The conventional "frog man" rubber suits of other navies was not up to the tasks of the UDT swimmers. After the war a professor at a California university was hired to do some tests with a neoprene foam sheet material made by the Rubatex Corporation (they bought the technology in the 1930's from Germany). This professor invented the "wet suit" which was commercialized and improved by some California divers and dive shops.

In the 1950's, this material and technology became available to the new sport of SCUBA diving. In the early 1960's, Rubatex became successful in laminating nylon jersey four way stretch knit fabric to the foam neoprene sheets of the G-231-N high grade material to give the sheets more exterior strength.

The invention of the first "air tight" zipper for early space suits by an English company made the last technical step needed to allow a drysuit to be fabricated from neoprene foam sheet material. A Swedish company developed the drysuit inflation and deflation (exhaust) valves and brought out the Poseidon UNI-suit with a watertight entry zipper that started at the back of the neck and went down through the crotch and back up to the middle of the front. When the popularity of this drysuit became apparent, many wet suit manufacturers went on to develop their own neoprene dry suits.

Diver's Temperature Tolerance Chart for Water Conditions

This chart can be used as a guide for both SCUBA and Surface Supplied dive planning. However, the individual diver's physical condition, body fat and recent experience in cold water will, in some cases, influence how long each diver can withstand exposure to different temperatures ranging from moderate to extreme.
