1. Ask yourself what you will use the suit for. Competition? Training? Pool? Outdoor? Depth? Can you afford two suits? Can you afford changing suit every two years? Do you easily get cold?


2. Choose type of NEOPRENE.

Neoprene are made by different manufacturers (Heiwa, Yamamoto, Freedown)   the they all have slightly different qualities. Heiwa is said to be more durable. Yamamoto more stretchable. Freedown is very smooth but only come with opencell inside.


3. Choose QUALITY OF NEOPRENE. ECOLINE is somewhat cheaper. NEOFLEX professional is somewhat better and slightly more expensive.


4. Choose DENSITY of neoprene. Light, medium or heavy density. The more density the more durable but less flexibility. Heavy density also does not get as much compressed in the deep. (Hint: It is said among freedivers that there is very little buoyancy change even in medium density. HD suits are actually for divers staying at depth for long periods).


5. Choose THICKNESS of suit. The thicker the warmer. The thinner the more flexible. Do not  worry about getting to warm   If If so, just let water enter the suit. A thicker suit will change more in buoyancy at depth – compared to a thin suit.


6. OUTSIDE LINING If you freedive outdoor for recreation/training you need to protect the neophren from cliffs. You need a outside lining like nylon. With smoothskin open cell you will glide more (competition) but it gets thorn more easily.


7. INSIDE LINING or COATING. Without lining (open cell) the suit will stick to your body (therefore enhance warmness) and be more flexible, BUT you will need lubrication (soap) to get into it. To avoid this you can choose a coating. A coating will make it slide more easily onto your body but you will lose the advantages of open cell. If you need more durability then choose an inner lining. Coating is NOT a lining it can not be sewn in therefore will not make the suit stronger but it is more easier to get into in comparison to open cell. Most coatings are made to reflect heat.



- A common solution for freedivers is Heiwa medium density with an inner coating. If competing choose smoothskin on the outside, if training in "wear and tear" environment choose an outer lining.

- You cannot combine a stretchy inner lining with a more rigid outer lining and vice versa.

- Do not try to buy one suit that will do two things for you.

- Jacket and trousers does not have to be same linings and thicknesses.

- You can buy an extra jacket that is thicker for winter freediving.

- High waist gives your more breathing, and if you have too pee you dont have to take the whole jacket of.

- Long John gives more neoprene over the essential torso that has to be warm (colder countries) but a thinner "extra suit" (2mm tight vest) is said to be more effective solution.

- It will take some e-mail correspondance to finish of your order since Eliossub is very keen on details. Do express yourself as clearly/simple as possible since their english is not perfect.





Yamamoto 45, ultra soft, ultra comfortable, but more delicate but not as much resistant to compression in the deep.


Heiwa, very elastic, warm and resistant to compression. The heiwa is an High quality rubber, always elastic, warmth and good for deep divings. (30/50mts)

Ecoline, elastic, soft and cheaper, but not as high quality.


Freedown is a new neoprene made in Smoothskin slide on the outside (fastest suit). This is the best neoprene for deep competition dives. It is the fastest suit they make. And it is even more durable than different coatings.


There is also a sandwich choice with for instance two neoprene layers on each side of nylon stretch.


The Nam Liong neoprene is an ultra-soft rubber, very very comfortable and perfect for shallow divings. (10/20mts)

The Black Shadow is made by Heiwa with black coating cell inside and stretch nylon or smoothskin outside. (very slippery to get into and warmth)

COATINGS (are painted on the open cell)


Titanium (first generation)- the cheapest coating.

Gold coating (the second generation) warmer and more

resistant to wear and tear.

Black Coating (the last generation) very warm and durable but not as easy to get into as copper.Black coating smooth is another choice which slides on more easily.


Copper coating and the new Black coating, is a painting put over smoothskin (not over open cell), But it is a little less elastic and little less adherent to the body compared to open cell.


Copper coating and the new Black coating, is a painting put over smoothskin (not over open cell), so is very very easy to wear and slide into. But it is a little less elastic and little less adherent to the body.


Gold, black and copper coating are the most expensive, also because they are combined with Neoflex professional neoprene.


LINING that only goes on the inside.


Thermic plush is the classic solution, resistant, easy to wear and warm (this is the cheapest).


Thermic pile is a new lining, little less hairy, but ultra stretchy and warm (used by scubadivers and people that want an elastic but resistant suit).


Superelastic lining. A common choice. Goes well with smoothskin on the outside. The Superelastic lining is a 500% stretch nylon to use only inside.



LINING that is made for the outside.


The Superstretch lining is a 400% stretch nylon perfect to use outside.

The Stretch nylon or Nylon elastic is a 300% stretch nylon to use inside or
The Nylon standard is a 100% stretch nylon to use inside or outside.


- Lycra is a lining, used by scubadivers because it has very bright colors and also by spearfishers because it is more durable against tears and cutting (but it's little less elastic!)


- Anti-tear is a special brush-nylon that is very very resistant, used for people who work under water.


- Shark-skin is made with rubber (like smoothskin) but the surface is made with "Scales".

It's more resistant than classic smoothskin BUT less slide in the water.


- Kanoko is a fabric, more elastic than classic nylon standard, and more durable.

Used by freedivers that want a more durable suit but also a stretchable suit. This suit will last longer. Comes only with open cell or copper coating on inside.


- Smoothskin (is not a lining) the open cell has been made smoother. Delicate.

1.       Type of neoprene (check availability here)

2.       Density of neoprene

3.       Ecoline or neoflex

5.       Long Johns or high waist. Freedivers usually chose jacket with hood, otherwise water can slip in to the suit when swimming fast.

6.       Inside; lining, coating or smoothcell or open cell.

7.       Outside; lining (nylons) or smoothcell or sharkskin.

8.       Color: Red, blue, gold, silver are some new colors. Remember that you can have a mixed design at an extra price.

I have a feeling EliosSub likes to make tight suits. I have lately taken to adding 0.5-1 cm to all measurements, specially on a thicker more rigid suit.




-One idea is to have a suit that you can turn inside out. Smoothskin glide on one side and superstretch nylon on one side. Either side can go out. Works well - friend of mine tested it.

- Another idea is to gor for a 3mm suit and buy a 3 mm shorty for those early/late season dives. A shorty on the outside will keep you warm during warm-up.


Arm length
Keep your arm in normal position by your side and measure from tip of humerus to wrist bone

Chest measurement
proceed as follows: 1. Raise your arms 2. Take the chest measurement well below the armpits 3. Lower your arms 4. Take the chest measurement with the tape close fitting under the armpits, in a relaxed position and breathing normally. Women need to measure over breasts and a second measure under breasts

Shoulder-blade/crotch length
Place the tape measure on the backbone and measure from the first vertebra at the base of the neck to halfway sown the curve of the buttocks 4 cm beneath the coccyx

Measure at the level of the navel

Measure over the buttoks on the widest part.

Measure at the widest point

Measure at the widest point

Inside leg
Measure length from crotch to ankle bone

Head circumference
Measure at the forehead

Measure at the centre of the neck on the Adam's apple // Indicate in a
separate note if the neck is visibly long or short and if the chin is
particularly pronounced

With your arm at your side measure at the centre of the muscle

Forearm circumference
Measure at the widest point a few centimetres below the elbow

Measure at the smallest point

measure a few millimetres above the ankle bone

Shoulder breadth
Lay the tape measure on your shoulders and measure the breadth from
tip of humerus to tip of humerus.
