A wetsuit keeps you safe and comfortable whilst scuba diving.

So it’s an important piece of dive gear to have.

But which is the best scuba diving wetsuit for you?

The kind of wetsuit you need for scuba diving mostly depends on the environment and type of diving you plan on doing, but it also comes down to personal preference.

With so many styles and types of wetsuits available you’re probably struggling to know where to start.

That’s why we’ve pulled together a list of the very best wetsuits for scuba diving.

Plus we’ll be sharing everything you need to know about scuba diving wetsuits so you can make the best choice for you.

So, let’s get started.

What is a wetsuit and how does it work?

A wetsuit is an exposure suit, often made from neoprene, that divers wear to keep themselves warm and protect their body against scrapes and abrasions.

Wetsuits work by trapping a thin layer of water between your body and the wetsuit. Your body heats up this layer of water which keeps you warm and prevents you from losing too much heat to the colder water surrounding you. Further insulation is also provided by the tiny air bubbles that are trapped within the material of a wetsuit.

For a wetsuit to function effectively it needs to fit you properly. If it’s too loose then water will keep flushing through and quickly take heat away from your body.

Why should you get your own wetsuit for scuba diving?

In addition to being safe, it is extremely important to feel comfortable when you are scuba diving. And having your own scuba diving wetsuit is one of the easiest ways to ensure you are comfortable throughout your dive.

You might be thinking ‘Can’t I just rent a wetsuit?’

Yes, you can normally rent a wetsuit when you go scuba diving. But it’s common knowledge amongst divers that rental wetsuits aren’t always the best.

And here’s why…

Very few dive shops will have a variety of styles and thicknesses to suit your personal needs. Everyone’s body is unique and it’s very rare that a rental wetsuit will fit your body perfectly. And you already know that a wetsuit only works if it fits you properly.

Even if you’re lucky and it does fit you well, the rental wetsuit might not be the right thickness for you personally to stay warm enough throughout the dive. Or maybe it’s too thick and you feel uncomfortably hot during the dive.

Lastly, rental wetsuits are subject to a lot of wear and tear. Used all day every day, they become thin and therefore much less effective at keeping you warm. Not to mention all the holes and dodgy zips. And let’s be honest they’ve definitely been peed in many times!

So investing in your own wetsuit for scuba diving, or multiple depending on the dive conditions is the best solution.

Frequently Asked Questions

Why do I need a wetsuit for scuba diving? 

As much as we love it, we humans simply aren’t biologically equipped for spending long periods of time underwater.

We don’t have that thick layer of fat that other marine mammals, like whales, dolphins, and even otters, have to keep themselves insulated. A wetsuit is our layer of insulation.

Water conducts heat away from your body 20 times faster than air. So without a wetsuit, you’ll get cold pretty quickly, even in tropical waters. And in some environments, you can easily end up with hypothermia.

And even if you never feel the cold when you’re diving, a thin wetsuit is perfect for avoiding accidental cuts, scrapes or jellyfish stings.

What thickness of wetsuit do I need for scuba diving?

Scuba diving wetsuits come in different thicknesses depending on the temperature of water you’ll be diving in. Most wetsuits are available in 3mm, 5mm and 7mm options but you’ll also find some 1mm and 2mm wetsuits from tropical waters.

Below are the general recommendations for wetsuit thickness for scuba diving:

2mm: Tropical waters above 85 F / 29 C

3mm: Warm waters between 70-85 F / 21-29 C

5mm: Temperate waters between 60-70 F / 15-21 C

7mm: Colder waters between 50-60 F / 10-15 C

A wetsuit with a thickness represented by 2 numbers, for example, 5/3mm, then the first number is the thickness of the torso and the second is the thickness on the arms and legs.

Remember to consider what type of diver you are when deciding on the thickness of your wetsuit. Some divers feel the cold a lot easier than others.

Where we might freeze our fins off in anything less than a 5mm long wetsuit you’d be sweating in anything more than a 3mm shortie.

Still unsure about what thickness to get?

If you dive in both tropical and temperate water then you might want to consider purchasing 2 different wetsuits. Yes, it’s a bigger investment, but long term it’ll pay off as you’ll be more comfortable underwater and be able to fully enjoy all of your dives.

Alternatively, you can look at purchasing a neoprene vest to add insulation around your core. A diving hood can also make a big difference as we lose most of our heat during a dive from our heads.

Should a scuba diving wetsuit be tight?

A scuba diving wetsuit should be tight but not restrictive.

If your wetsuit is too loose it will keep letting water in, which will take the heat away from your body very quickly. But if it’s too tight, you’ll struggle to move properly and you may find it difficult to breathe.

How do I get the right fit for a scuba diving wetsuit?

As we mentioned above, a scuba diving wetsuit needs to fit snugly against your body for it to function effectively. You should have to struggle a little to get the wetsuit on, but it shouldn’t be so tight that you have trouble zipping it up.

Check out this video for a simple guide on how to make sure your wetsuit fits you properly.

Front zip vs back zip: What’s better for a scuba diving wetsuit? 

Honestly, this is down to personal preference so choose whichever zip style you’re most comfortable with.

A back zip wetsuit is often easier to put on because the opening that a back zip provides is much larger than a front or chest zip. They also tend to last longer as they’re subject to less movement. However, a front zip is much easier to deal with if it gets stuck, especially if you’re alone. And they’re also less prone to water flushing in.

Do I need a short or long wetsuit for scuba diving? 

The style of wetsuit you need depends on the environment you’re diving in and your personal preference.

Short wetsuits are great for shallow diving in warm water conditions and offer flexibility and freedom of movement. They’re easy to put on and lightweight for travelling.

Long wetsuits offer additional warmth and protect your legs and arms from accidental scrapes and jellyfish. Many divers prefer a long wetsuit when reef or wreck diving, particularly in areas with more venomous marine life.

Can I use a surfing wetsuit for scuba diving?

The quick answer is yes, you can use a surfing wetsuit for scuba diving but it won’t keep you as warm as a scuba diving wetsuit.

Surfing wetsuits tend to have thinner shoulder and arm sections to allow more flexibility and movement. This means that they are less effective at retaining heat. Scuba diving wetsuits will keep you much warmer as they are specifically designed for being fully submerged in the water for a prolonged period of time so

Is it ok to pee in a scuba diving wetsuit? 

There’s a well known saying in scuba diving that there are only 2 types of divers:

Those who pee in their wetsuit and those who lie about it.

While we’re not sure if that’s 100% accurate we do know that peeing in your wetsuit won’t cause any damage.

And as long as you properly clean your wetsuit afterward then you won’t have any issues.

What do I wear underneath a scuba diving wetsuit?

Most scuba divers just wear their normal swimwear underneath their wetsuit. You can also wear a rashguard or skinsuit underneath for added comfort and warmth.

Or you can choose to go commando. Whatever floats your boat, there are no judgments here!

How long does a scuba diving wetsuit last?

On average, a good scuba diving wetsuit should last anywhere from 2 years to 10 years or more. However, this will depend on how heavily you use it and how well you look after it.

All wetsuits lose elasticity over the years and can shrink a little as the neoprene cells collapse. But as with any piece of scuba diving gear, if you invest in high-quality equipment and look after it, then it will last you much longer.

Is it easier to put on a scuba diving wetsuit wet or dry? 

Unless you’re wearing a dive skin or other skin-tight clothing that will allow the wetsuit to slide on effortlessly, it is easiest when both you and your wetsuit are either wet or dry. The most difficult scenario is trying to tug a damp wetsuit over dry skin or shove a wet body into a dry wetsuit.

Our recommendation is to put your wetsuit on when you’re fully in the water. So, if you can, jump in the pool or ocean first and slide into your wetsuit there.

What’s the Difference Between a Wetsuit and Drysuit?

Lucky for you, we have an entire post on the differences between the two. For more information check our wetsuit vs drysuit post. The simple answer is that a drysuit ideally keeps you completely dry, while wearing a wetsuit, you guessed it, you get wet.

The Best Scuba Diving Wetsuit for you

Ultimately, the best scuba diving wetsuit for you is the one that you feel most comfortable in. And is suitable for the location you’re visiting and the type of diving you are planning. We’d also recommend checking out our drysuit guide for more info on those.

There’s a huge difference between the wetsuit you’ll need for a dive liveaboard in the Maldives and shore diving in Sardinia, for example.

Having the wrong wetsuit can easily ruin your whole dive, and in some situations even become dangerous, so it’s important to take some time to find the right wetsuit for you.
