What is a wetsuit?
A wetsuit is a close fitting suit made from neoprene which minimizes the amount of water entering the suit and thus keeps the diver warmer and more comfortable underwater. A small amount of water enters the suit and settles between the skin and the neoprene. This water is warmed by the body but this is only effective if the suit is of an excellent fit and is well made.
A wetsuit is the most common thermal protection worn by divers and performs well in water temperatures as cold as 10° or 12° and within commonly accepted recreational depth and time limits. Minor punctures or tears are easily fixed and are not usually severe enough to stop a day's diving.

Cost of buying a wetsuit?
As in most cases, you get what you pay for. A top quality wetsuit can cost from $300-$500, but if you are only going to do a few open water dives a year, you may find you do not want to spend this sort of money and it may be wise to choose a cheaper model.

Making your choice?
Three factors should determine your choice of wetsuit: planned maximum depth, anticipated water temperature, and amount of time spent in the water. For example, instructors who spend long periods stationary while teaching entry-level courses and are acclimatized to the water temperature will often need a thicker wetsuit than a holiday diver. Acclimatization occurs most obviously for a diver making the transition from cold to warm water diving.

Water temperature?
Before buying a suit, check exactly where you want to dive. This is one of the main criteria for the correct choice. NEMO offers a wide selection of diving suits for different situations.

Tropic Suits

 : 

25 °C to 28 °C

Wetsuits

 : 

18 °C to 25 °C

Semi-Dry Suits

 : 

7 °C to 20 °C

Compression ratio of the material!
The compression ratio is an important factor that determines the level of protection. In addition to the technical details of the suit construction, the neoprene material itself and the lamination of the material influence the quality and warmth of the suit. This is because neoprene has a low grade of warmth protection. Only the gas bubbles in the material provide protection against cold, and make the material flexible and soft.
There are different grades of neoprene on the market. A good quality neoprene can increase the price of the suit by 50%. This explains why some suits are so cheap. Normally the suit is tried on in the shop, but a very soft material does not mean that you now have the perfect suit. If the neoprene is too soft, the air in the material is compressed very quickly and with increasing depth, the warmth-protection decreases dramatically.
In cheap neoprene, not only is the air compressed very easily, but under pressure the cells may crack and collapse and the danger of water entry in the neoprene increases. Very soft material is often not fully vulcanized. This means after some dives to greater depth, the material shrinks and produces what is called "orange skin". Only an irresponsible manufacturer will use these materials for diving suits. Normally these kinds of materials are appropriate for surface sports such as windsurfing and boating.

They can allow you to get too warm!
We need to remember that it is just as important to avoid overheating both before and after a dive. A hot and bothered diver is a familiar sight, and is usually the result of putting on exposure suits a long time before entering the water. Dehydration is known to increase the body’s disposition to decompression sickness, as it significantly affects a diver’s ability to reduce bubble formation in the blood.

Wetsuit Construction!
The thicker the suit the more warmth and buoyancy is attained, however, some people may find that the thickest neoprene may make them too buoyant. Advice can be sought from an expert, who, by asking questions about your swimming abilities, should be able to help you choose the right suit for you. Top of the range wetsuit manufacturers have spent a lot of time researching different materials and designs to give divers the best possible product. All seams should be double glued and reinforced with stitching or thermal tape on the inside, or a combination of the two. This method prevents water flushing through the suit, as the seams should be watertight. Smooth skin or mesh, (black rubber on the outer side of the suit) should not be stitched on the outside seams, as this will cause the neoprene to split when stretched. The neoprene should feel soft and stretchy to the touch and be of a good make. The most expensive suit is not always the best suit for you, so do take advice.

Fit and cut of the suit, preventing water circulation within the suit.
The largest organ of the human body is the skin, the key to maintaining natural temperature balance. If it is too hot, the skin absorbs sweat and thus cools the body. If it is too cold, we usually use warm clothing. Water has a much higher heat transmission than air. The body cools down to temperatures lower than 36 degrees Celsius that in certain cases will cause dangerous injuries. Diving suits are the diver’s second skin as they maintain body heat and thus fit is of utmost importance. A wetsuit must not be too tight or too loose. In particular, arm, leg and neck openings must fit snugly, but a suit which is too snug is dangerous. First, it cuts the blood circulation. Further it generates extensive stress on the material, which can lead to cell, nylon and yarn breaks, which are not covered by any guarantee. Therefore, a careful selection of raw materials combined with perfect fit of the suit to the body will provide the highest possible measure of safety for a long, enjoyable dive. NEMO guarantees a perfect fit and the best insulation through continuously adapting suit size to the change of the body. A diving suit is made out of different materials. We care about the smallest details in the procurement of materials as well as the manufacturing process, because the quality of a suit is the sum of the quality of its components as well as the strict control of its manufacturing. NEMO uses the best raw materials and offers a suit tailored to your individual needs, requests and proportions.

Comfort counts if you want to be safe!
When buying a wetsuit, a diver must not only consider the correct choice for the environment but also its comfort and fit and its relationship to other equipment. An uncomfortable BCD and wetsuit combination, for example, can draw a diver's attention away from more important matters such as monitoring dive time and depth. It can be quite uncomfortable to wear a thin warm-water suit with a 'hard pack' BCD for instance.

Care and Maintenance!
Any rubber on a wetsuit is susceptible to damage by sharp objects such as fingernails, so care should be taken when putting on the suit and storing it. Rinse the suit in fresh water after use and hang inside out on a padded hanger allowing plenty of air to circulate. Avoid drying a wetsuit in the sun and you will double its life. Never roll a suit and store it as this can permanently damage the neoprene. If a lubricant is necessary, baby oil is best as it can be washed out using a mild detergent. If you see a problem, get it fixed, they won’t fix themselves. Minor repairs are fairly easy to undertake yourself; a small tube of neoprene glue and seaming tape is a good investment for small nicks. With care a good quality wetsuit should last you a few seasons if you follow the advice above.
