Childrens Wetsuits and Rash Guards:
Tips on Buying a Kids Wetsuit

Plus Our Picks for Best Childs Suit and Rash Guard

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.

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.

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

Our Picks For Best Child's Rash Guard

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

For this I picked a Tuga model. This long sleeve rash guard has an SPF of 50+ so you can protect your child's sensitive skin.

This is a cute rash guard and your girl should look nice and stylish playing out in the water.

Best rash guard for girls

Lots of parents gave it high marks for its looks and, more importantly, its ability to protect their child from sunburn. It has a higher neck so even less sunscreen is needed.

The pros and cons of this rashguard are:


  • 50+ sun protection
  • Lightweight
  • Quick drying
  • Good quality, wears well, no fading
  • Chemical free
  • Cute, stylish
  • Comfortable


  • Leaks dye (3 reviewers)
  • Sleeves stretched (3 reviewers)

If you prefer, this rashguard also comes in a short sleeve version. You can find the details here.

The company also offers this in a set with swim shorts for a complete stylish looking set. See all the information on the set here.

Best Boy's Rash Guard

For the boys I also picked a Tuga model. This company gets lots of great reviews from parents so I went with the tried and true.

Like the girls rash guard, the boys is also chemical free and has a higher neck for extra protection from the sun.

The boys versions comes in lots of different colors and designs so your child (or you!) is sure to find one that he loves.

The pros and cons after reading the reviews are:


  • 50+ sun protection
  • Chemical free
  • Soft, lightweight fabric
  • Fits well, good quality
  • Quick drying
  • Doesn't fade
  • Cool designs


  • Wore out easily (1 review)

If you prefer, the company also offers a short sleeve version. You can find this rash guard in a short sleeve version here.

We hope you found this guide to picking the best childrens wetsuits or rash guards for your child useful. May they have many hours of warm, fun in the sun and water!
