Chlorine Vs. Swimsuits

Chlorine Vs. Swimsuits

When it comes to shopping for a new swimsuit, it’s important to look for something that is comfortable, helps you feel confident, and lasts a long time. One way to ensure your swimsuits last as long as possible is to get one that can combat the different chemicals found in swimming pools, mainly chlorine. So what do you need to know about chlorine, and what should you keep an eye out for when swimsuit shopping?

Is Chlorine Bad for Swimsuits?

Yes, chlorine is bad for your bathing suit. Over time, this chemical eats away at the material. This can cause the elasticity to wear out and the material to flake and shred. Chlorine can affect the coloring of your suit causing it to fade. You’ll find that your swimsuit will slowly break down if it is not made with chlorine-resistant materials or if you’re not practicing proper care and upkeep. 

What Can Make a Swimsuit Chlorine Resistant?

Now obviously not all swimsuits are falling apart and changing colors. So what is it that can make a swimsuit chlorine resistant? The key is to purchase swimwear that is made with the right materials to combat the negative effects of chlorine. While some swimsuits are clearly identified as being made with chlorine-resistant materials, which is extremely helpful, others aren’t. As such, it’s important to know which types of fabrics and materials to look for when shopping for a new swimsuit.


Spandex is commonly used in swimwear. LYCRA® XTRA LIFE™ spandex is especially durable and long-lasting, standing strong when going up against things that can be harmful to other materials used in swimwear, such as sun rays, sunscreen, and chlorine. It will last up to ten times longer than regular spandex without thinning, becoming see-through, or becoming stretched out. Our chlorine resistant swimsuits are made with LYCRA® Xtra Life™ spandex ensuring that they will last longer and maintain their shape over time. 


Nylon is another high-quality fabric to keep an eye out for when shopping for chlorine resistant swimwear. Nylon is a strong fiber and has proven to stand the test of time, ensuring your swimsuit will last. It’s well known for being a tough material, and is less likely to shrink than other fabrics that are commonly used to make plus size swimsuits, making this material one that you will certainly want to be on the lookout for!


PBT is a material that is similar to polyester in that it is naturally form-fitting and comfortable to wear. This is another popular material for chlorine resistance as it does not absorb water. While PBT is stretchy, it’s not quite as stretchy as polyester. So if this is a priority, you’ll want to keep the elasticity in mind when shopping around for a new tankini.

Average Life of a Swimsuit

The average life of a swimsuit depends on the quality of the suit and how well you take care of it. Some suits will only last you a season, perhaps around six months. If you invest in a bathing suit that is made with high-quality materials and you take the time to properly care for it, you can find that a swimsuit can last for years to come. 

How to Wash Chlorine Out of Your Swimsuit

So what is the best way to wash and care for your swimsuit to ensure it will last? The first thing you want to note is the temperature of the water you use to wash your bathing suit. You want to make sure it’s lukewarm or cold. Avoid using hot water.

Water alone does not wash the chlorine out of a swimsuit. Instead of throwing your suit in with a regular load of laundry with ordinary detergent, we recommend hand-washing your bathing suits with mild soap or even baby soap. This ensures that your one-piece swimsuit is handled as gently as possible instead of being jostled around with strong detergents.

As swimsuit season comes upon us and you start browsing for some new swimwear, be sure to take some of these tips into consideration. When you get a suit that is made with the right materials and you take the time to properly wash it, you’ll find that your swimsuit will last for many summers ahead!
