Scuba diving is a physically challenging activity that requires your whole body to work in perfect sync. It’s an activity that can get challenging especially when the water temperature drops. Scuba diving can become uncomfortable and even unsafe for you if you don’t prepare yourself properly for it. To have a safe and enjoyable scuba diving experience, you need the right kind of dive suit or wetsuit to keep you warm and comfortable in the water. Scuba dry suits are designed with divers in mind as they are specifically tailored to withstand the challenges of dry, or hot, water diving. They significantly reduce moisture on your skin while also increasing your thermal protection against cold water.
There are lots of different types of wetsuits available on the market these days; however, most of them cannot be used for scuba diving unless they are modified or made from specific materials. The following article will help you understand what exactly a scuba dry suit is, its pros and cons, and how to choose one that suits your needs best.

BEST SCUBA DRY SUITS
A cold water scuba dry suit can vary enormously. From what material? Boots or socks? To what type of seal is best? The questions for first-time scuba dry suit buyers are endless. That is why we have included below the most frequently asked questions for first-time scuba dry suit buyers making up our most comprehensive guide to drysuits yet.
Which material should I choose?
Neoprene drysuits are thicker and far better at insulating your body heat, unlike other drysuits. The material is often squashed giving them less of an effect on buoyancy and as they are so thick, neoprene drysuits tend to be better at maintaining temperature.
Membrane drysuits – also known as shell or laminate drysuits – are effectively just the outermost layer of a drysuit. They do not retain any warmth but are far lighter and easier to pack. These suits are ideal if you are looking to dive in varied water temperatures as most of the temperature of the suit is maintained from the undergarments worn.
Fusion drysuits are a unique product. They are a combination of two drysuits in one. The suits are more flexible and more streamlined. They provide the most flexible suit on the market. An oversized scuba dry suit core adds additional flexibility, whilst the hardy outer skin is built for environmental resistance. The outer skin is made from a host of materials varying from neoprene to Kevlar.
BEST SCUBA DRY SUITS
1. Front entry or back entry?
Front entry scuba dry suits are easy to get into. They normally have a diagonal zip going from thigh to shoulder and can be put on without the aid of a buddy. Despite being easy to get into however the opening is often not as spacious as back entry scuba dry suits. Back entry scuba dry suits have a zipper across the back of the shoulders. These are easier to get into, but you will still need your dive buddy to assist you in getting in and out.
2. Which type of seal is the best?
Latex seals are flexible and cheap to replace; however, they are also rather easy to tear. Remember not to pull too hard on the latex when entering the scuba suit. Intuitively, they cannot be used by anyone with latex allergies. Lastly, they are known to stretch and degrade over time.
Neoprene seals are thicker and tougher than latex on the outside. The inside glide skin, however, is more fragile so do handle it with care. Although they provide even pressure against your body, they cannot be used with dry gloves and do not stretch as easily as other seals. Silicone seals cannot stick to anything and thus require a ring system. They are easily replaceable and do not react to UV as much as neoprene or latex. They provide an excellent seal but are very fragile, so care is needed when trying to put them on.
3. What do all these valves do?
Chest inflation valves place air into the scuba dry suit. You can get a rotational inflation valve however these tend to be more expensive than the fixed valves.
Auto dump valves allow excess gas to escape. If you twist them to the left or right, you can normally change the amount of air that can escape from the valve. You can also press the valve in to increase the amount of air leaving the valve as well.
Cuff dumps are simple one-way valves that allow gas to vent out. Although easier to use than a shoulder dump they can often let water in on the surface.
Pee valves are normally an additional extra. Pee valves allow you to go to the toilet during a dive. They are rather simple for men but much more complicated for women.
4. What extra add-ons come with a scuba dry suit?
Thigh pockets are handy pockets on the sides of the thigh. These are useful for keeping in equipment and normally have a bungee cord for attaching certain items.
Warm necks are simple neoprene covers that cover neck seals that trap water in front to keep you warm. They also have a hole at the bottom for the water to drain from.
Braces are found inside the suit. They hold it up when you are walking around on the surface, so you can take the top half of the scuba dry suit down and remain cool.
Built-in undersuits are only currently found on the Waterproof DX1 drysuit but are relatively self-explanatory.
Cuff guards are silicone guards that protect latex and silicone cuff seals from abrasion.
Knee pads can protect a dry suit from wear and tear.
Telescopic torsos are more commonly found on front entry scuba dry suits to give more space. They allow you to adjust sizes and are ideal if you still have some room to grow.
5. Should I choose boots or socks?
Boots are often attached directly to the scuba dry suit. They have a tough sole and come in many sizes. They’re sturdier than socks and are often cheaper.
Socks and rock boots are a much lighter alternative than boots but normally more expensive. The socks are thin, not especially sturdy and easily ripped. Rock boots, on the other hand, can be easily fitted around socks and come in many shapes and sizes.
6. Which zip is best?
Drysuits have two different types of zipping covering the front and back. Brass zips are the traditional style of zipping and require lubrication. They can create a very strong seal but can be easily broken so it is important not to bend them too much and always wax them. By waxing the zipper, you keep it free of corrosion and protected against the elements allowing for a smooth entry every time you use a scuba dry suit.
Plastic zips are newer and easier to move up and down. These also don’t require as much maintenance as the older brass zips. Most scuba dry suits also have a simple Secondary zip that covers outside of drysuit to protect it.
7. How should I size myself up for a drysuit?
Always remember you’ll be wearing an undersuit underneath the scuba dry suit so measure yourself with clothes on. Do not increase the measurements and measure your neck, chest, waist, hips, inside leg, wrist, height, and weight. Once you’ve taken these measurements you can size yourself up against the manufacturer’s guidelines. If you cannot find a scuba dry suit of the correct size, then you can always investigate buying a made-to-measure suit instead. Also, don’t forget your shoe size will be a size larger due to the thick socks you will be wearing.
8. Is there anything wrong with second-hand scuba dry suits?
Whilst second-hand suits are very popular and most of the time you can get a good bargain. Second-hand drysuits can have a multitude of problems and some are not that cheap to fix. A brass zip, for example, is very fragile but also one of the most expensive parts of the scuba dry suit. If scuba dry suit zips are damaged they can be expensive to replace, similarly, latex and silicone seals are also expensive to replace. Exercise caution when buying second hand and try to see it first before buying. Maybe even see if you can take it to a local dive store for a pressure test. Even better, buy a new scuba dry suit and be guaranteed it’s not going to leak.
9. How much should a scuba dry suit cost?
When considering scuba dry suit diving you should be prepared to spend a bit of money on the suit. Drysuits can cost anything from a couple of hundred dollars to several thousand, so do your research and be confident when you make your purchase. Lastly, dry suit scuba diving is a one-of-a-kind experience – allowing you unrivaled, underwater freedom – so when your kit is bought and paid for, get out and there and use it well!
