Parents, Did You Know?

Girls who are young in age have a tendency to prefer swimsuits that are vibrant in color and have a soft stretchy feel so that they may swim and play in the water comfortably. This is wonderful, as parents will enjoy swimsuits that are made from non-shrinkable materials. Additionally, due to the stretchability and quality of several of our best girls' swimsuits, your little girl may be able to wear her swimsuit for more than one summer.

Parents, Did You Know?

There is nothing that is more frustrating than having to buy your kid numerous swimsuits during warm seasons because each of them has deteriorated after one or two uses. With our recommendations listed above, you certainly would not have that problem. Choosing a swimsuit that is composed of high-quality fabric is important so that it will be able to withstand high chlorine levels and saltwater concentrations.

Other Factors to Consider

Protection

As a spectacular bonus, the majority of modern swimsuits have built-in sun protection. Meaning, that you will not have to lather your kid’s entire body with sunscreen or sunblock. With a swimsuit that has built-in protection from the sun, your kid will have more time to enjoy themselves as they wear their new girls' swimsuit. Even better, as a parent, you will be able to relax as you will not have to chase your child down to reapply sunscreen every hour, which could become quite tiresome.

Moreover, many of our swimsuits can be used in a variety of environments such as in wooded areas where your family hikes. It is amazing that something as simple as an awesome swimsuit can greatly aid in ensuring that everyone has a fun time.

Comfort

Flexibility is essential when in any body of water. All of the swimsuits above allow for optimal mobility whether your child is in the water or on land. Although having flexibility on land is important, have flexibility while in water is even more significant inasmuch that being in the water is not our natural habitat as humans. It is fantastic that all of our girls' swimsuits allow kids to move naturally in water as they would on land.

Flexibility is not only a practical factor that makes swimsuits comfortable but safe as well. If a swimsuit hindered your kid from natural movements in the water, it could pose a potential threat. Safety is important when swimming or doing activities around any body of water. With our best girls' swimsuits, your kid will be able to move freely and comfortably.

Frequently Asked Questions

q: What type of sunscreen should I use for my kid?

a:

When it comes to choosing a sunscreen for your kid you want to ensure that it does not contain harsh chemicals or fragrances. This is important so that your child will not have an allergic reaction. Sunscreens that are made specifically for kids usually don’t contain harmful chemicals like avobenzone. For that fact, the sunscreen will be less irritating on sensitive skins such as kids', while doing an adequate job of protecting them from harmful sun rays. When using a new type of sunscreen be sure to perform a skin patch test to make sure it is suitable for your kid’s skin.

q: What’s the difference between UPF and SPF?

a:

UPF is short for Ultraviolet Protection Factor. SPF is short for Sun Protection Factor. UPF is usually a safer option as clothing integrated with UPF absorbs and reflect harmful rays. In contrast, SPF creams absorb sun rays and need to be reapplied every hour. Additionally, chemicals from SPF creams could seep into your body.

q: What is a Monofin used for?

a:

While swimming with a mermaid tail, if a Monofin is inserted, kids can properly swim. The Monofin also helps the mermaid tail to keep its shape for a more realistic look. Without a Monofin, kids will have a tough time swimming with the mermaid tail on and the tail looks very floppy as the Monofin provides structure.

q: How do I prevent my child from chafing due to her swimsuit?

a:

Chafing is one of the most annoying non-life-threatening issues. To prevent chafing, it is important that you make sure your young girl isn't dehydrated. For the fact that the more hydrated your kid is, the more likely she is to produce sweat. Sweat actually acts as a protective measure towards chafing. However, the longer your kid sits in sweat and other types of dirt or debris, the more friction that will build up and result in irritation. To prevent this, always keep your kid’s swimsuit cleaned and do not allow her to sit in her swimsuit for too long after she swims.

q: Is the SwimZip Baby Girl Long Sleeve Sunsuit Romper with UF UPF 50+ swimsuit machine washable?

a:

Yes, the SwimZip Baby Girl Long Sleeve Sunsuit Romper with UF UPF 50+ swimsuit is machine washable. It is recommended that you wash it on the delicate cycle due to the light weight of the fabric. It dries very quickly, so there is no need to toss it into the dryer, as the heat from the dryer could cause it to deteriorate. It is very important to always follow the manufacturer's guidelines for washing and drying a swimsuit.

q: What type of swimsuit clothing material is safest in the sun?

a:

Fabrics made of nylon, wool, and cotton can naturally absorb some UV radiation. Many of these fabrics have threads that are made from elastic to pull the fibers together, tightly. This reduces and tiny holes in the clothing that may allow UV light to touch the skin. Polyester and Lycra are much more protective than cotton and wool as they absorb more UV rays. Commonly, fabrics that are light in weight do a better job of protecting skin than heavier fabrics.
