How to choose the size of your diving wetsuit

Neoprene wetsuits protect you against the cold. But to provide optimal protection, the wetsuit must be the right size. Check out our guide on how to choose the right size for you.

How to choose the size of your diving wetsuit

DIVING WETSUITS WORK BY LETTING A THIN LAYER OF WATER ENTER BETWEEN THE NEOPRENE AND YOUR SKIN IN ORDER TO PRODUCE HEAT. THEREFORE, IT IS VERY IMPORTANT TO CHOOSE THE RIGHT SIZE IN ORDER TO HAVE THIS SECOND SKIN.

The benefits of a good diving wetsuit 

A number of factors contribute to the quality of neoprene:~- Its elasticity, which is due to the micro-bubbles enclosed inside the neoprene. The higher the number of bubble, the more supple the material. However, it is important to pay attention to the water pressure, which can crush the bubbles and reduce the warmth of the material.~- Its capacity to keep out the cold can vary according to the thickness of the neoprene, the seams and the bonding between the panels.~- Its strength over time will prevent it from becoming worn too quickly, thanks to the quality of the neoprene, the seams and the bonding. It is also necessary to take good care of the neoprene by rinsing both sides in cold, fresh water, and to leave it to dry in the shade and in a well ventilated place to avoid affecting the quality of the neoprene.~- Its capacity to return to its initial shape is determined by the elasticity of the neoprene.

But don’t worry if you don not feel quite at ease when you try on the wetsuit for the first time. Your diving suit must act like a second skin, so it is quite normal if you feel uncomfortable when trying it on in a store at ambient temperature. Pay attention to the tightness around the neck and the rib cage.

Take measurements when choosing your wetsuit

Before buying a wetsuit, remember to take your measurements in order to choose the right size for you.~Use a tape measure to take measurements against your skin.

Bust 

Take these measurements using a tape measure. Take the measurement on the largest part of your bust, as shown in the photo below.~~In addition to what we have already mentioned, you need to be parallel to the floor when taking these measurements, then tighten the tape measure while breathing normally. Then read the measurements.

Waist 

Take these measurements by putting the tape measure above your tummy button, at the slimmest point of your body, as shown in the illustration. Then, repeat the same operation while raising your head and breathing normally. Hold the tape measure firmly in place to take the measurements.

Our final tips on how to choose your wetsuit

Despite all these tips and size guides, it is always preferable to visit a store and to try on several sizes to decide which one best matches your body shape. Your chest size is the most important, because it enables you to breathe properly. It does not really matter if there are a few folds on your thighs or torso, but the thermal protection will be less efficient.

Your wetsuit really works like a second skin. So you need the tightest possible fit! When trying on a wetsuit, make sure that you can move freely. You must not feel at all oppressed and you must be able to breathe easily.
