Features Of Kids Wetsuits

There are quite a lot of different features and considerations that you need to choose from when buying wetsuits for kids. Here are some of the main parts of kid’s wetsuits to take into consideration.


The first thing to think about when buying a wetsuit is the thickness. Kid’s wetsuits typically range in thickness from 2mm to 5mm. 2mm wetsuits are ideal for water temperatures down to about 16°C and 5mm wetsuits are good for water temperatures down to about 14°C. The thicker the wetsuit, the more protection it will offer and the warmer it will be. 

However, thicker wetsuits are also more restricting, and they can be uncomfortable to wear under the hot sun if the water isn’t very cold. This is why it’s always important to understand how thick you need the wetsuit to be based on where you will be using it. 

When looking for kid’s wetsuits, some will say 3/2mm thickness or 4/3mm thickness. This means the thickest part of the wetsuit is 3mm while the thinnest part of the wetsuit is 2mm. The torso will be the thickest part and the arms will be thinner.

Full Length or Shorty

Kid’s wetsuits are either full length, covering the arms and legs completely, or they are shorties with short sleeves and legs. Both have advantages and disadvantages. 

The obvious advantage of a full-length wetsuit is that it will be warmer. You get more protection and coverage, so it is a better choice for very cold waters. The downside is that full-length wetsuits are a bit more restricting. They can also be uncomfortable to wear when not in the water.

Shorty wetsuits don’t offer complete coverage over the arms and legs, so these exposed areas can get cold. They’re not the best wetsuit options for very cold waters. However, they are more comfortable and less restricting to wear. This makes them ideal for kids to wear in the sun when they’re out of the water. 


Wetsuits are made from neoprene, but the specific types of neoprene can differ quite a lot. The best wetsuits for kids use a very stretchy kind of neoprene. This is more comfortable to wear, and it will continue to fit kids as they grow. 

Wetsuits also often incorporate other materials too, like softer material around the neck lining and knee pads for abrasion resistance.

The Fit

One of the most difficult things about buying wetsuits for kids is getting the right size. Kids grow very quickly, so you don’t want to get a wetsuit that only lasts a month. If the wetsuit is too loose though, it won’t help to keep kids warm. If the wetsuit is too big, it will just flush the cold water straight through it.

Your child’s wetsuit should fit comfortably without having any loose openings around the arms, neck, and legs. When looking for the best wetsuits for kids, having a wide range of available sizes is ideal.

Wetsuits for Different Activities

When choosing a wetsuit for kids, always think about the activities they will be doing. If your kids will be wearing the wetsuits for general beach days and water activities in warmer conditions, then a 2mm or 3/2mm will be fine.

If your kids will be spending long periods of time in the water, for things like surfing or snorkeling, then you might want to get a 4/3mm or even a 5mm if the climate is very cold. 

Wetsuits don’t just protect kids from the cold, they also offer great protection against the sun. If this is a major concern, then a full-length wetsuit is best. 

You can also get wetsuit tops that are much easier to wear and add extra warmth while in the water. However, these tops won’t be warm enough for extended periods in the water in colder climates.
