Wetsuit guide - What should you consider?

When getting your first, or your next, wetsuit there are a few important things to think of such as:

  • what for and where will you be using it
  • thickness
  • design

The wetsuit is a neoprene wear purposed for water sports such as surfing, wakeboarding, kitesurfing etc, as well as recreational activities such as tubing, which keeps you warm and comfortable in the water. Children’s wetsuits are also often used as highly protective layers for sun exposure and cold water.

People often think that the wetsuit is supposed to keep them dry but what it actually does is trap a thin layer of water which your own body warms.

1. Type of wetsuit and thickness based on temperature as a key factor

Before we get to technicalities, we should take a quick look at what water sport you are into. Normally there are four main types of wetsuits - hooded fullsuit, fullsuit, shorty (also known as spring suit), and Long Johns. They can also vary, for example, full suit with short sleeves, or shorty with long sleeves.

Since the main purpose of your wetsuit is to keep you warm, choosing the type of wetsuit depends much on the temperature of the water/air you will use it for. The chillfactor is also to be considered here.

For example, wind sports such as surfing, kitesurfing, windsurfing require thicker, respectively warmer wetsuits. Yet, they need to be flexible and durable, so you definitely need a good quality wetsuit. Wave skimboarding is similar. Basically, in those categories, is good to buy a full suit as a first buy and a long-sleeve/short-sleeve shorty as a secondary.

On the other hand, inland surfing normally is in warmer, calmer waters, so there is less need for big suits (e.g. wakeboarding, flatland skimboarding, waterskiing). Here, the first buy would be a shorty (long/short-sleeved) and the second one would be a fullsuit for the winter/off season.

SUP and kayak is often done in Long John (and a windproof layer, if needed) due to the constant movement of shoulders and arms, which can be a bit harder and irritating in a thick fullsuit.

We made a table to make it easier choosing the right thickness and type of wetsuit depending on the waters you will be playing in. So it is very important that you research your spot beforehand.

Keep in mind that the chart gives guidance but the choice of wetsuit varies also based on your personal needs and preferences. Bottom line is, you need to be warm and comfortable!

2. How to read the thickness?

The variation in temperature suitability is based on the level of activity, outside temperature, and your weight. So keep those in mind as well. The UV lycra mentioned for the warmest conditions is a special sunscreen t-shirt that you can use to protect yourself from the sun.

As you can see, the thickness of the neoprene is not always a round number. But what does it mean when it is written with two numbers divided by a slash?

The first number indicates the thickness of the neoprene in the torso/hip area and the number after the slash indicates its thickness at your arms and legs. For example, 4/3 mm means that your wetsuit has a thickness of 4 millimetres at the torso and 3 millimetres where it covers your limbs. This is made so that you can keep your core temperature at a comfortable level and at the same time, have freedom of movement with your arms and legs.

3. Size and design...yes, it matters...a lot

  • Size

Picking the right size wetsuit is important because the tighter and closer fit you can get, without feeling uncomfortable, the more insulated you are. A good-fitting wetsuit should fit like a second skin and be able to keep this thin layer of water between you and the suit (but not too tight to stop your blood flow). To test if your wetsuit fits before you take it to the water, lift your arms over your head and stretch. It should slightly restrain but not restrict you to do so. Do a few squats and paddle with your arms in the air - if you can do those, then you most likely have a good fit.

The wetsuit should always feel tight around your neck (but not choke you) since this is an easy place for water to enter.

Apart from that, you get the wetsuits in standard sizing - XS, S, M, L, XL, XXL, or their UK equivalents - 4, 5, 8, 10, 12, 14. The only ‘catch’ here you may stumble upon is if you see an ‘S’ or ‘T’ after the size indicator which stands for short and tall versions of the standard size. For example, ST means size small/ tall.

  • Design (Zips and Seaming)

In regards to the design, we already mentioned that it is important how much water enters from your neck, for example. Zipper types and the seeming are important design features affecting how much water entry/exit you get. The less the better.

Chest zips are the best in regards to water entry because it is harder for the water to get in or out. This makes the chest zip design warmer and is relatively younger design;

Backzips allow easier access to the water (but also for you to get in the wetsuit) and can feel a bit colder. The back zip design is also older compared to the chest design, however, it allows easier access and comes at a lower price;

Front Zip gives both you and the water very easy access and normally those wetsuits feel colder than the rest

The seaming is also important in regards to keeping you warm and preventing water from entering.

Flatlock stitching means that the neoprene panels have been stitched together on the outside and on the inside of the wetsuit

Sealed - refers to the panels being blind stitched and then glued to stop water from entering. It is needed for lower temperatures

Sealed and Taped means that after stitching and glueing, a tape has been placed over the glue on the inside to keep the warm air trapped inside.

4. What makes a good wetsuit?

Just like any other product, neoprene comes in different quality. A good quality neoprene holds a lot of air in it, which makes it a better insulator and respectively warmer. Also, it should be durable and stretchy.

Basically, a good wetsuit allows less water to go through it, fits and insulates good and is stretchy and durable. Normally more stretch means less durability but a good quality wetsuit can be both. Best quality wetsuits are normally 1mm less think, durable, with more stretch, more comfort, and simultaneously same insulation as a thicker one because of a good quality neoprene.

Ready for the water?

To sum up:

  • You need to think first is what kind of sport and where you will practise
  • Then you need to keep the water temperature in consideration
  • Find the right size
  • Choose a suitable design

And finally - have fun!
