Children's Wetsuits and Rash Guards:
Tips on Buying the Best One For Your Kids

Plus Our Picks for Best Childs Wetsuit and Rash Guard
(Updated & Expanded For 2022)

Buying childrens wetsuits and rash guards can help both you and your child. If your little guy or girl is comfortable and warm in the water with a kids wetsuit on - it makes for a better experience for both of you.

Or if he doesn't need the warmth, he can get full protections from the sun from a proper rash guard.

And who doesn't love a win-win situation?

Whether swimming, scuba diving or surfing, you’ll want to choose the kids wetsuits or rash guards that provide the maximum protection and comfort.

Guide to choosing a kids wetsuit

Let's start with childrens wetsuits since there is more to know about them to ensure you get the best one for your child.

Having the right information at your fingertips goes a long way to getting your little swimmer exactly the wetsuit he needs.

There are some basic criteria that apply to both adult and child sized wetsuits.

(We have a full free wetsuit buyers guide  which you can check out but we will go over the most important elements here.)

There are also some issues that make buying childrens wetsuits a little more challenging than adult suits. We will also address those issues in this article.

Thickness of Wetsuits for Kids

Whether you are buying childrens wetsuits or adult wetsuits, the most important element is suit thickness since this is what provides warmth in cool water. Wetsuits are produced on a thickness scale, which measures thickness of body and arms and legs.

Children's wetsuits - having fun in the pool.

Having fun in the pool. A child's wetsuit will work here too.

Of course, everyone is different so what works for one person may not work for another. You probably have a general idea of how cold your child gets in the water. If he or she is always coming out blue lipped and shaking, you may want to try a slightly thicker child wetsuit to start out with.

The following is a general guide to help you choose a starting point for the proper thickness for your kids wetsuit:

  • 2 mm: Water temperatures above 85 F; my shorty is 2 mm and it is fine for me in the Caribbean
  • 3 mm: Water temperatures between 70-85 F; this is usually the norm for scuba diving in the Caribbean
  • 5 mm: Water temperatures between 60-70 F
  • 6.5 mm Water temperatures between 50-70; at the lower end you are getting into drysuit territory - probably not water your child will be swimming in.

You will see some suits with 2 numbers, for instance a 4/3 full suit. A note on A 4/3 full suit has a 4mm thickness in the body and 3mm in the arms and legs. The thicker portion covers the core of your body to keep you warmer, while the second number covers your extremities and is a little thinner allowing some extra mobility. 

Type of Childrens Wetsuits

There are three types of kids wetsuit. Those that cover the whole body and go to the wrists and ankles are full suits and offer the most warmth and protection.,

Childrens wetsuits that have short legs that end just above the knees and short sleeves are called shortie (shorty) suits. This is probably the most popular type of wetsuits for children that are swimming (as opposed to scuba diving) since it offers warmth but has more room for movement than a full suit.

Children wearing full wetsuits into the ocean.

Full wetsuits can keep your child warm in the ocean.

Childrens wetsuits that have full legs but no arms is called a farmer john.

The type that is best for your child depends on what they will want to do in it.

For scuba diving, especially in cooler water, a full suit is recommended.

If your child is swimming and running around in the water and just plain being a kid, and the water temperature is in the high 70's or so, shorty suits would probably be the best choice. They offer warmth but also allow for more flexibility. 

Quality of Kids Wetsuits

The quality of a childs wetsuit may be less important than the quality of an adult wetsuit. The reason being that your child is growing and the suit may only last a season or two as opposed to, say, the five years an adult can get out of a suit.

So a child is liable to outgrow the suit before they get full use from it.

Child wearing a wetsuit

This is not to say that you want the cheapest suit for your child since you want them to be comfortable (cheap suits tend to have seams that stick up and can be uncomfortable). But you also probably don't want to spend a ton of money on a suit that will only last a summer.

A medium quality childs wetsuit should be fine - offering comfort and protection at a reasonable price.

You can often judge the quality of the suit by how strong the seams are. The better the quality of the suit, the more secure the seams will be.

Seams that fit tightly together, are smooth (lay down), have blind or flat lock stitching (see our page on buying a wetsuit for details) and are reinforced by either glue or a second piece of fabric over the seam signify a well-made suit.

Seams that have bumps, ridges or exposed stitching are the sign of a cheaper suit.

Fitting Childrens Wetsuits

Before you purchase a kids wetsuit, you’ll want to make sure that it fits well. Of course, the best way to do this is by trying them on.

Only by seeing the suit on the child can you tell if it will provide the maximum protection and allow the proper amount of movement. If you buy online, check the return policy in case the fit isn't right.

A wetsuit is meant to be snug for a proper fit. If the childs wetsuit is too loose, water will run freely through it which makes it lose its insulating properties.

Of course, you have to balance this with your child's growth.

Though a snug fit is generally recommended to ensure maximum warmth, allowing a small amount of growth room in children’s suits can be doable and can be a money saver. But don't buy it too big or your child will not get any warming qualities from the suit.

While childrens wetsuits are meant to be snug, they should still be able to have movement. Have them cross their arms in front of their chest. If their movements are very restricted, you may need to go up a size and vice versa.

If you see folds in the suit at their armpits or crotch, you should go down a size.

It is hard to give a size chart since childrens wetsuit sizes will vary by manufacturer. But once you choose a manufacturer, almost all have a sizing chart to help you choose the right one for your child.

Our Picks for Best Kids Wetsuits 2022:
Shorty Wetsuits Under $50

To try and save you some time and to help make your choice a bit easier, we have read tons of reviews and ratings of childs shorty wetsuits (we will have a separate article on the best full children's wetsuits).

Our view is that if an overwhelming number of parents have a favorable review of a suit, chances are that you will have a good experience also.

As far as pricing goes, costs for childrens wetsuits will vary depending on the quality of the suit. However, most good quality children’s suits seem to range from $25-$100. In this, like almost everything else in life, you get what you pay for.

Since children will outgrow wetsuits, it can get expensive to keep buying new suits as they get older. To this end I have picked 3 well rated suits that are all under $50. In addition I also give you our pick for best value kids suit (see below).

In case you don't mind spending a little more money, I also give you a shortie wetsuit pick that gets great reviews and is at a higher price point.

(If a link doesn't work or an item isn't available, please let us know. We strive to keep this up to date as possible. We appreciate your help. )

Choice #1:

Our pick for best kids wetsuit - a Realon model

Our first pick for best childrens wetsuits in 2022 remains this Realon model. It continues to rack up the positive reviews from parents.

It is still getting great reviews from the vast majority of purchasers (rated 4.6 out of 5.0 from 1,600+ reviews; it got an even better rating of 4.9 out of 5.0 for snorkeling purposes) and most say they are extremely satisfied. 

One common comment was their child didn't want to get out of the water since they weren't cold - so be forewarned! :)

This wetsuit has flat lock seams and a durable zipper that can withstand the pulling and tugging from kids according to most reviews.

It is made of a thick 3mm neoprene material and has an adjustable collar for maximum comfort.

This pick also gets our nod for Best Value Children's Wetsuit of 2022 coming in at just under $30 for all sizes. I think this is a great price point for the suit you are getting.

This suit is made of 2mm neoprene, so a little thinner than our first pick but still thick enough to do the job. It has a front zipper making it easy for a child to take it off and put it on by themselves (wish I could say that for my wetsuit!).

This wetsuit for kids also boasts a UPF 50+ which should make the adults happy. It is available in sizes 4-12 and there is a size chart provided by the manufacturer to ensure you child gets a good fit.

The pros and cons of this children's wetsuits pick are as follows:

This model was bumped down to our third pick in 2022 for best kid's wetsuit. This model is still a solid choice and has garnered over 470+ positive reviews with an average 4.5 out of 5.0 rating.

Like our first pick, this wetsuit has flat lock seams and an inner layer panel under the zipper for more comfort for the child. It also features a hidden key pocket which may prove useful for your child. Or they can have fun with it anyway!

Aunua has made this wetsuit for a child with an extra long zipper, making it easier for them to put on and take off by themself.

It is made of a thick 3mm neoprene material and has an adjustable velcro collar for additional comfort.

This kids wetsuit is available in sizes 4 to 16 which according to the sizing chart is suitable for a weight range of 40-135 pounds or kids to teens.

Our Pick For Best Child's Wetsuit 2020:
 Shorty Wetsuit $50+

Best child's wetsuit -an O'Neill model

The above picks of best children's wetsuits are all moderately priced at under $50. However, I wanted to give an excellent choice for those that don't mind paying a little more for a child's suit.

Looking at all the choices, the one suit that stands out is an O'Neill model. This was my pick for the last couple of years and it still stands the test of time as my pick for best higher end children's shorty wetsuit in 2022. It is coming in this year at around the $75 price range for most sizes and colors. Not cheap by any means but by all the reviews, it is worth it.

What struck me is how many people said they bought another one or were going to buy another one when their child outgrows their current one. Now that says alot!

This wetsuit got an excellent 4.8/5.0 rating  from 155+ reviews and is available in sizes 4-16. It has flatlock stitch for comfort and also has seams placed where they won't chafe as much when moving. This is a 2mm wetsuit.

The pros and cons of this higher priced pick for best children's wetsuit in the high end are as follows:


  • Excellent quality
  • Great fit
  • Very comfortable
  • Warm
  • Good range of motion
  • Easy on/off


  • Strong smell (7 reviews)
  • Runs small (3 reviews)
  • Neck area chafes (4 reviews)

Our Picks For Best Child's Rash Guard 2022

If your child doesn't need the extra warmth childrens wetsuits provide, a good alternative for sun protection would be a rash guard. This will help protect them from small abrasions and keep their skin out of the sun. With a SPF rash guard you will need to put less suntan lotion on them which is always a plus!

I have picked a couple of highly rated rash guards for both boys and girls. They come in all sizes and lots of different colors so you should be able to find one that suits your child.

Our picks for best children's rashguards are:

Best Girl's Rash Guard 2022

Choice #1

For 2022, this City Threads rash guard has hung on to the top spot. They continue to get an excellent overall rating of 4.8 out of 5.0 and reviews keep coming in - they now have over 620+ reviews.

What also made this product stand out is the number of reviewers that said they:

  • recommend it to other people,  
  • are buying for their other children,
  • have more than 1 product from this company and (last but not least) 
  • will be buying more once their child outgrows their current rash guard. 

Now that says alot!

Best girls rash guard 2020

This rash guard is made in the USA and the company states that no extra spray or retardant is used in the manufacturing process. Rather the sun protection comes from the weave of the fabric. 

It also has UPF 50+ and reinforced stitching. You can choose from many prints and styles both long sleeve and short sleeve. The company also offers matching products (swim briefs, leggings, hats, dresses, etc.) to make an outfit if you want :)

Depending on the style and color sizes run from 3 months to 16 years.

Quite a few of the reviews said it runs large so you should size down. So this is something to consider when ordering. Quite a few reviewers gave their child's size and what they ordered so you can also check against that.

Choice #1

The top spot for best boy's rash guard in 2022 goes again to the OshKosh B'Gosh brand. It was a close call between #1 and #2 this year but I went with OshKosh due to the higher number of ratings/reviews.

Choice #2

As I stated above, it was another close call between the top 2 spots in 2022. Just being edged out but still in a great #2 spot for best boy's rash guard in 2022 goes to again to the well known Nautica company.

Aside from coming from a well known and trusted company, this boy's rash guard has garnered some great ratings scoring an excellent 4.8 out of 5.0 based on 275+ reviews/ratings.

It is made of  82% polyester and 18% spandex and has a UPF of 50+. This style rash guard has a raglan half sleeve, ending just above the elbow. It also has a higher mock neck for extra protection from the sun.

Choice #3

Holding up the #3 spot in 2022 is this Tuga model. This company continues to get lots of great reviews from parents but it was overtaken by the more well known brands the last couple of years.
