 Are you looking out to buy a new wetsuit for a scuba diving vacation but don’t know where to start? Before you drift dive into the coast of Florida or explore the underwater splendor of Fiji Islands, allow us to impart a few guidelines to help you select a matching wetsuit that would provide ultimate comfort and flexibility as you cruise the depths of your intended diving destination.

Shorty or Full Suit?

Shop through online retailers and surely you will learn that wetsuits don’t come in a single style or design for that matter. Some are outfitted with sleeves while others are not. A particular wetsuit may be designed to wrap around the entire body while another one would only conceal the torso, with the garment rising a little over the knees. It would save you time to buy whatever feels right as to price and preferences, but then common sense would dictate that wetsuits come in different forms and sizes for a reason. Common terms to encounter include jumpsuits, farmer johns and shorties though selection should be focused on the purchase of either shorties or a full suit.

If you plan to dive in warm water, particularly in tropical or subtropical locations, a sturdy piece of neoprene shorties will give ample protection and insulation. Now if you’re adventure should lead you to cold water locations and at thermocline depths at that, settle for a thick, full suit instead of shorties. Getting the entire body insulated from the chilly conditions of the depths is necessary to prevent hypothermia and provide utmost comfort to the diver as well.

Thickness of the Material

Neoprene is a compressible garment that has become the standard material for wetsuits due to its ability to respond efficiently to changes in pressure with a corresponding shift in volume or aid in the diver’s neutral buoyancy. Warm water dives would require the neoprene wetsuit to carry a torso thickness of 2mm while for cold water dives, torso thickness should vary from 3mm to 5mm where its application is directly proportional to the drops in temperature of a particular dive spot.

Be very particular with the size and fit

The one size fits all criteria does not apply to wetsuits. As much as possible, the garment should snuggly fit the diver’s body since a poor fit around salient sections, such as the arms and around the thighs, allows more water to collect on these areas instead of a thin film, which compromises the material’s ability to keep you warm.

Overall Flexibility

The flexibility of movement underwater should be a primary consideration. If a thick wetsuit inhibits easy movement then it loses its utility no matter how efficient it may be in keeping the diver warm. Check if the wetsuit comes with a front zipper for easy donning and if the garment is outfitted with spandex panels which heighten its flexibility.

 When it involves fixing the surfing board, there are ways that you can use to personally fix the board. But you must know how to use the correct tools if you have to succeed in the repairs. Remember that the wrongs instruments may further worsen the damage or you can even cause damage to places where no harm was ever experienced. Therefore, always avoid a situation where an attempt to cure a damage may lead to further harm.

First and foremost, you will have to appreciate how these materials are made and what should be done or not done to them. You ought to know that you may cause serious injury to the windsurfing board and this may eventually put your windsurfing board out of use. Anything uncompromising to these materials is not good to be used when fixing the board.

What Are The Things That Should Not Be Done To The Foam Hub Board?

Your first objective in fixing damage on the board is to make it have one and the same quality as it had ahead of being damaged. Therefore, nothing new should be added to the old board. This will not give it the same texture or quality as before. Never add or make use of those elements that are incompatible with the foam hub. This will include materials which consist of polyester or vinylester. Remember that these materials have styrene compounds in them and this will dissolve the foam hub.

Also steer clear of using wax because this is not going stick well. They will further liquefy when under the influence of high temperatures and may further soil the region of repairs. Keep in mind that duct strip will also act poorly to your foam hub as it is going to leave humid deposits and will not also stick as you will expect. These are the more reasons why you must use only the most accurate materials needed for fixing your windsurfing board.

Why Use The Most Accurate Repair Materials?

One of the simplest reasons to use the most accurate repair elements is to make sure that repairs are appropriately done. If the damage on your board is so slight that it does not result to any significant damage, fixing it is not difficult. In most cases it will be easily fixed by affixing another sticker on the hole. But if the damage is more severe, a Ding Stick or Marinetex is very much needed. But remember that this will also take much time.

You should begin by knowing that the foam of the windsurfing board will swell when under the influence of heat and will detract under cold conditions. This means that you will have to wait when temperatures are really down ahead of fixing the foam. Remember that leakages may further occur when expansion on the foam is being experienced. And this will likely be caused by the materials that you put on the foam.

Before you apply anything on the foam, make sure it is clean. After this, the area should be scratched to make it a bit rough. Any screw should be taken out before fixing the foam. It is best to use a Ding or Epoxy Stick because they are more durable and will give the best results. These should always be a necessity in your repair kit.

Slash a portion of the ding that is big enough to cover the damaged area. Make sure you close the remainder of the ding. Remember that exposure to air will spoil the ding. Use the piece of ding to cover any area until you are sure that the damage should have been accurately fixed. Remember that there should be no air space in it. This will further cause leaks on the foam. This should be left throughout the night to dry well. You can paint again the fixed area if the new color does not conform to the old one.

A number of people think that any wetsuit is good for just about anything. This is farther from the truth. Wetsuits come in so many variations that the buyer needs to be mindful of the types available.

Before we delve into the types of wetsuits, we need to understand the purpose of this garment. Wetsuits are protective clothing for individuals in water environments. The purpose of the suit is to keep the body warm. In fact, it purposely traps water into the suit so that it acts like a protective layer from coldwater exposure. The suits are made of a fabric called neoprene, a synthetic rubber created by DuPont. The fabric essentially allows warmth to be trapped because of the nitrogen gas in the synthetic rubber. Because of the low thermal conductivity, heat has less chance to leave the body. However, human skin in contact with water causes heat to lose rapidly from the body.

So what should we look for in wetsuits? It all depends on what you plan to do. The sport could be water skiing, diving, snorkeling, surfing, or swimming. There are wetsuits that are made specifically for these types of activities.

Otherwise, you determine the weather and conditions of the environment and make a decision based on the wetsuit thickness. Thickness is measured by millimeters (mm), so a 1mm wetsuit will literally mean that the fabric’s thickness is 1mm. For warmer waters, that don’t cause too much loss of body heat, consider 1mm to 2mm. If the water temperature is 45 to 70 degrees, consider a thickness of 3mm to 4mm. For very cold weather below 45 degrees, one might wear a 5mm suit with a hood.

The quality of the wetsuit can be determined by the seam construction. As with any clothing, tightly woven seams are indicators of quality. Conversely, loosen seams can allow exposure to the elements, which is poor quality. The purpose of the suit is to keep all elements away from the body. A wetsuit that’s closely seemed or flushed is seal proof.

Besides neoprene, there are other fabrics. Spandex, a thin fabric that can stretch very well, can be used in tropical weather conditions. It can protect one from the effects of the sun. Thermoplastic is another fabric that’s around 1.2mm. It has a little more insulation than spandex, but it can be used very warm climates.

The important part of choosing a wetsuit is trying it on. The best suits are the one that fit snug on the body, provided that it doesn’t suffocates or limits your movement. Test the suit by flexing or moving your body parts. Once you’re in the water, the suit should be much more flexible. Learning how the suit responds to your movements will allow you to better get a feel for the product.

Wetsuits varies in size, shape, quality and flexibility. Understanding these qualities will better help you to choose the right suit. If you’re not sure which suit is right for you, consult a retailer for the advice.

 Even in the tropics, divers have to guard against thermal loss, but for divers who blow bubbles in chilly, temperate conditions–water ranging from the low 50s to the low 70s–staying warm is imperative. When the water’s this cold, it doesn’t take much to get uncomfortably chilled and stay that way. Good news: Today’s 7mm wetsuits offer better fit, features, comfort and thermal protection than ever before. In this review, Scuba Lab takes a look at 12 new 7mm wetsuits, but first, let’s review how a wetsuit really works.

Wetsuit Basics
Wetsuits are made with neoprene rubber, a closed-cell foam that traps millions of tiny gas bubbles. These bubbles in the neoprene act as insulation, and this, combined with a snug, sealed fit that minimizes the amount of cold water that enters the suit, is what keeps your body heat from escaping. In order for a wetsuit to keep you warm, it should: 1) be thick enough for the temperature of the water you’re diving in, 2) have seams, seals and zippers that minimize water intrusion, and most important, 3) fit like a second skin.

Materials
Stretch vs. Warmth A layer of material, usually nylon, lines each side of a wetsuit’s neoprene rubber. The purpose of the outer layer is to provide some protection for the neoprene, while the inner layer, or lining, is more for comfort. Some suits use no inner lining, and instead have a smooth-skin interior. This offers more warmth because the whole suit seals against your skin, minimizing or even eliminating water flow, a key feature of an effective wetsuit. The downside: wetsuits with smooth-skin interiors, with some notable exceptions, are more difficult to put on and take off, and the inside of the suit is more prone to damage.

The trend in recent years, especially in 7mm suits, is toward more stretchy neoprene to increase comfort and flexibility. A stretchier suit is easier to put on, is super comfortable and is able to maintain a snug fit by conforming to your body. The downside: stretchier neoprene compresses more at depth than denser, stiffer, standard-stretch neoprene, reducing its insulation capabilities. Because of this, some wetsuit manufacturers use more traditional compression-resistant neoprene, which is then cut into anatomically shaped panels and sewn together to add flexibility.

Seams
Keep Them Watertight Nearly all seams on 7mm wetsuits are glued and blind-stitched. First, the suit’s neoprene panels are glued with two or three coats of neoprene cement. Next, the seams are sewn together to prevent them from pulling apart. This is done with a blind-stitch, where a needle penetrates only the top layer of the material on either side of the seam, without punching all the way through the neoprene.

There are slightly different methods used in creating a durable waterproof seam. One is running a bead of liquid silicone-based urethane over the glued seam on the opposite side of a blind-stitched seam, making one side of the seam look like it’s been "welded" together. This process is more waterproof, since you’re not poking holes in the neoprene on one side, and more durable because the liquid weld bonds to the seam virtually everywhere contact has been made, rather than just at the stitch points. Glued-and-taped is another method, where flexible bonding tape is applied with heat and pressure over the glued seam on both sides, eliminating the need for any stitches at all.

Seals
The More the Better Some water always seeps into a wetsuit, but the goal is to keep it to a minimum. The most common water entry points, in order of importance, are the neck, wrists and ankles. Some manufacturers put sealing systems on these entry points. Starting with the most effective, they are:

A note on neck seals: 7mm suits are designed for temperate to cold water, environments that require not only a thick suit but a hood. Most wetsuit hoods tuck inside the collar, but this generally breaks whatever neck seal the wetsuit has. If you wear a standard wetsuit hood, don’t worry about what kind of neck seal the wetsuit has; instead, tuck in the hood and then adjust the collar as snug as possible to minimize water flow. If the wetsuit has a first-rate neck seal and you don’t want to lose it, consider wearing a dry suit hood. These overlap the collar rather than tuck inside, maintaining the integrity of the seal. Another option: some manufacturers offer wetsuit hoods that have a band of smooth-skin sewn around the neck. Tuck the hood into the collar of the suit so that the smooth-skin band makes contact with the smooth-skin neck seal. They bond together, preserving the seal and keeping you dry, warm and comfortable.

Zippers
Often Overlooked

Choosing a 7mm suit with a vertical back zipper or one with a horizontal front zipper is a matter of preference. Front-zipper suits tend to be easier to put on, but the zipper track can affect flexibility in the chest and shoulder areas. Back zippers lay in line with the spine and tend to be more comfortable, but you may need help when zipping up. Whether back or front, the zipper creates the greatest potential for water entry. To combat this, most suits have a zipper underflap that lies between a diver’s bare back and a heavy-duty zipper track, which helps block water flow (and adds cushioned comfort). Some suits use two sections of smooth-skin neoprene, one on each edge of the zipper track. When the zipper is zipped up, the two sections of smooth-skin seal against each other. Finally, a couple of suits use zippers with overlapping teeth that reduce water seepage, and here and there, you’ll find a 7mm suit with a dry suit-type zipper with its teeth sandwiched between layers of rubber that create a truly watertight seal.

Fit
The Ultimate Challenge Of course, none of the above–the seals, the seams, the zippers–matters if the wetsuit doesn’t fit. Gaps in your armpits and spaces between your legs, behind your knee 1ff8 s or along your spine fill up and pump water inside your suit, sucking the heat out of you.

A properly fitting suit fits your body like a second skin, with no gaps or spaces. Finding a good fit can be difficult: Everyone has a unique shape, and even standard sizes like small, medium and large differ by manufacturer. Some suits tend to be designed for muscular divers, others fit lean divers better. Some manufacturers offer a dizzying array of sizes, others offer only the basics. Bottom line: To get a snug-fitting suit, try on as many as you can. If you can’t find a stock suit that fits, find a manufacturer that offers custom-made suits. The Pinnacle Polar retails for $489.

Wetsuits are meant to keep divers warm by giving them thermal protection. There are some important guidelines which a diver should learn regarding the wetsuit he might acquire and use. First of all, it is important to know that they are usually made from neoprene; most of the times open cell neoprene. Besides, when wetsuits have a coating added to the neoprene they are easier to be worn and taken off.

The practice of free diving and scuba diving imply the use of different kinds of wetsuits. While a 5 mm thick wetsuit would be ideal for keeping warm a free diver, a scuba diver would need a 7 mm thick wetsuit to achieve the same results. Besides, while most free diving wetsuits don’t have a zipper, most scuba diving wetsuits do come with them.

If you are looking for an open cell neoprene wetsuit, it is important that you have into account the fact that they can be easily damaged. If, for example, you are going to use jewelry under your open cell neoprene wetsuit, this could easily damage it and open it, so you should be very careful with it or try to find another kind of wetsuit instead of it. If you have long finger nails you should be careful as well since you could damage it while putting it on or taking it off.

It is also important to have in mind that free diving wetsuits should fit the diver in order to work well and give him the proper thermal protection. If a free diving wetsuit is loose or too tight it would not give the protection it should and it could even become a problem since it could be an obstacle to the diver’s movements.

There also are recommendations on how to maintain and store your wetsuit. In order to store it properly while you are not using it, you should hang your wetsuit up avoiding folding it since that could damage it. Besides this, you should make sure to wash the suit after using it and make sure to wash all salty water off from it.
