Best Children’s Wetsuits for 2023

Give your child one of the best children’s wetsuits that ensure comfort, protection, and enjoyment in all sorts of water sports.

Wetsuits not only warm your little ones but also protect them from the sun’s UV rays, sticky sand, stinging sea creatures, and abrasions.

It also provides kids with a natural buoyancy although it is not a substitute for a lifejacket.

What elements should we consider when buying Children’s Wetsuits?

Here are the features that you should consider before buying a kid’s wetsuit:

Material and Thickness

Most of the wetsuits for children are made from a hypoallergenic material known as “Neoprene”, which is gentle on the skin. But, there are factors and options when considering the thickness.

Factors to consider the ThicknessClimateWater TemperatureActivities kids’ choose
Thickness levels2mm2.5mm3mm4mm5mm

Normally, you can choose a 2.5mm thick wetsuit for both warm and cold water while a 2mm kid’s wetsuit is generally good for sun and skin protection in summer.

You should go for something at least 3mm thick in colder weather. It should be noted that as the thickness of the wetsuit increases, it loses a little flexibility.

Thus, if your children will be actively participating in sports, go should still go for a slightly thinner wetsuit i.e. choose one with 3mm thickness on the body and 2mm thickness on the arms and legs for added flexibility.

Sun Protection

Re-application of sunscreens still can’t protect your aqua-tots from UV rays, as the water rinses them off. Protect them with a good quality wetsuit that genuinely offers UPV 50+ protection.

Right Size and Fitting

Choosing the right size is crucial to give your kid a snug fit i.e. the neck to be a close fit so they have no difficulty breathing, however, the ankles and wrists to be a firm fit to keep water flushing into the wetsuit.

Kids using a wetsuit for some serious water sports should opt for a snug (tighter) fit. On the other hand, they occasionally hit the water, choose one size bigger, as your growing kid can quickly outgrow wetsuits within a season.

Types and Lenght

There are four options available in children’s wetsuits:

Full: This wetsuit comes with a complete and long-sleeve feature that covers the whole body, arms, and legs of the kid. Ideal for cold water but also good for warmer temperatures (depending on thickness).

Besides providing the most warmth, a full wetsuit also offers the most protection from the sun’s UV rays, abrasions, stinging sea creatures, and other hazards.

Shorty/Spring Wetsuit: It features short sleeves and a cut above the knees, while the length of the cover can differ on the arms and legs.

Generally, cop to the warmer temperatures and moderate seasons that’s why known as the “spring suit”.

The shorty wetsuits with thicker models are still good at protecting core body temperature. 

Long John: This wetsuit comes sleeveless and entirely covers up the legs. Normally, suitable for warmer temperatures and also offers extra mobility to the upper body for swimming. A little drawback is that it does leave the arms unprotected. 

Separates: Finally, this wetsuit features a Two-piece wetsuit that is divided at the waist. It offers mixing and to match between tops and bottoms depending on the kid’s water activity, climate, and water temperature.

Wetsuit Structure

This factor is normally overlooked, however, the best children’s wetsuits should have good quality seams and zippers, as both affect comfortability and functionality.

Flatlock Seam

If you have a child that is too sensitive to the things that are touching their skin, then prefer the wetsuits with flatlock seams. Because a flatlock seam has no protruding material, thus, causes quite less skin irritation.

On the other hand, seams that have a raised section on the interior cause irritation to kids’ skin and lead to chafing.
