Best Baby Wetsuits and Rashguards

We started taking our children to the beach when they were just babes, and they took to the water immediately! What could be cuter than a baby giggling and splashing to their heart’s content? I certainly can’t think of anything!

You may be eager to take your little one to beaches and pools during the summer and even into fall, and that’s marvellous! I fully encourage introducing your bub to water as early as possible. However, you may be wondering about whether or not you need to include an infant wetsuit or rashguard on your list of essential baby beach items. 

Is such a thing necessary when your infant has all of those adorable leg rolls and double chins to keep them warm? Absolutely!

A person’s body will lose heat if the water is cooler than 98.6 degrees, which is probable for many beaches and outdoor pools. Your baby is also likely to be excited about their experience in the water, so they may not immediately indicate they’re cold.

Those factors, along with the fact that babies can’t actually verbalize that they’re chilled, are enough reasons to want to keep your bub as warm as possible while they’re in the water.

We’ve assembled a list of the best baby wetsuits and rashguards to provide the added protection infants and older babies need to stay warm in the water. With so many cute options, it may be impossible to choose just one!

Wetsuit vs Rashguard

What exactly is the difference between a wetsuit and a rashguard? Will a rashguard give your baby the same thermal benefits as a wetsuit? Let’s take a look:

Baby Wetsuits

If your goal is to keep your bub as warm as possible, an infant wetsuit or wrap is the best option. Wetsuits are often made from a 2mm or 3mm-thick neoprene material designed to keep a swimmer warm in a range of water temperatures.

Baby wetsuits can be shorties or a full-length design – it all depends on the climate and time of year you’re going to be swimming in. We recommend putting your baby in a close-fitting wetsuit if you have any plans of fully immersing them in the water for a long period of time (such as wearing them in a water carrier).

Baby Rashguards

While infant wetsuits are made with warmth in mind, baby rashguards serve a different purpose. Rashguards have thin fabric that’s designed to protect your bub from sunburns, skin irritation, and bites/stings while they’re splashing in shallow water. A baby rashguard works well in warmer water but doesn’t preserve much body heat in colder temperatures. They’re an excellent layering option underneath a wetsuit, however.

Baby Wetsuit and Rashguard Buying Guide: Features to Look for in a Good Baby Wetsuit or Rashguard

When you’re shopping for the best baby wetsuits or rashguards for babies, it’s important to look for several essential features. The ultimate goal is for your tot to be as comfortable and safe as possible, so consider the following:

Warmth/Thermal Protection

A chilled baby can quickly become hypothermic if they become too cold in the water, so make sure you’re dressing your bub in the correct material and layers. If the beach or pool is on the cooler side, an infant wetsuit with a rashguard underneath is the best choice. If the waters and outdoor temperature are more temperate, a wetsuit by itself or just the rashguard will keep your baby warm and comfortable.

Most baby wetsuits intended for warmth should be 2-3mm in thickness.

UV Protection

Remember that harmful UVA and UVB rays can damage your baby’s delicate skin even on overcast days. Sunscreen also only stays on for a short time in the water before washing off, and you don’t want a sunburnt baby!

Wetsuits and rashguards for babies provide an extra layer of UV protection to help you avoid having an irritable and uncomfortable infant later on. Always choose products for babies marked UPF 50+.

Material

You don’t want your infant wetsuit to be overly loose, as this leads to heat loss in cooler temperatures. Most baby wetsuit material is made of neoprene, and some brands offer different insulation levels for added customization. Babies can be quite wiggly, so the material should have some elasticity to it.

Look for designs with flatlock seams. This means the material is fused together and the material joints should cause less irritation to your child’s skin.

If you’re searching for a rashguard for babies, the material will often be a combination of quick-drying polyester and spandex to provide the ultimate stretchiness. Remember that a rashguard’s material is intended to be thin, so it will not do much to preserve your bub’s body heat.

Sizing

You want your baby’s wetsuit or rashguard to fit fairly snugly, as excess material works against heat preservation and becomes uncomfortable with extended wear. However, a wetsuit or rashguard that’s too tight can restrict movement and cause itchy rashes. You’ll want to aim for that perfect “in the middle” fit.

Think also about whether they will be wearing an additional layer of swim diaper underneath too.

We all know how quickly babies grow, so it’s best just to accept you’ll be buying a new one the next summer!

Skin Protection

Some people might be surprised by the number of skin irritants at beaches and pools, such as sea lice, jellyfish stings, and sand abrasions. The thicker material of infant wetsuits and even rashguards can protect your baby from harm and keep them happily splashing all day long.

Ease of Getting On and Off

Babies are notoriously tricky to dress, and it’s even more challenging to get a squirming infant in and out of a damp wetsuit or rashguard. You also have the added complication of needing to change soiled nappies while out and about. So look for a wetsuit or rashguard that easily unzips or unwraps for those surprise nappy changes on the sand.

Full Length vs. Shorty Wetsuits and Rashguards

If your bub is going to be splashing around in cooler than average water, a full-length wetsuit or rashguard will provide the most protection from the elements. However, a shorty wetsuit or rashguard will keep them cooler on the hottest summer days, primarily since infants can’t regulate their body temperature as well.

Differences in Designed Compared to Toddler and Older Kids Wetsuits

The main difference between an infant wetsuit or rashguard and those designed for older children is that you don’t really need to consider the mobility factor as much. After all, a baby isn’t going to be running into the water. You should look for a wetsuit or rashguard that will keep your bub snug, warm, and comfortable in or near the water.
