Otherwise, you are welcome to keep reading this article where we will look into the basics of “chlorine resistant swimwear”, understand it and answer any questions you might have about it.

Chlorine Resistant Swimwear – Everything You Need to Know to Make Well-Informed Decision

Chlorine Resistant Swimwear

Functional swimwear used to be boring and plain. Luckily, this has changed over the past decades and nowadays functionality can be equaled to fashion and style. Bright and vivid colors, stunning patterns and eye-catching details are in the game of the functional swimwear so you can wave goodbye to boring grannyish styles.

Chlorine resistant swimsuits are stated to last even 20 times longer than regular bathing suits.

When it comes to chlorine resistant swimwear, it is all about the material it is made of. Whether it is the construction or finish of the fabric, there has to be a reason to characterize it as resistant to chlorine.

Besides that, another important feature to pay your attention to is the colorfastness of the fabric. Nowadays, a majority of functional swimwear fabrics are resistant to the fading or running of color but there are different types and levels of this property.

In addition, it is important to remember that the deterioration of the bathing suit is accelerated when the effect of pool water is combined with the effect of the sunscreen lotion, oil or cream.

Choosing the Right Swimwear Fabric – Features and Functions

Everything starts with the choice of the right fabric. It can get quite challenging to choose the best swimwear material as there are many things to consider starting from a great number of quality brands on the market and ending with your intentions for the use of the bathing suit.

What are you looking for – the durable swimsuit lasting long, the great stretch of the bathing suit or swimwear fitting the best? Or perhaps you are looking for all of this?

If you know what you are looking for, it is more likely you will meet your expectations regarding the swimwear.

In general, there are several types of swimwear fabrics each one characterized by its features, functions and performance.

Whenever there is no Lycra® in the composition of the chlorine resistant swimwear material, it is referred to as chlorine proof swimsuits’ material.

Chlorine resistant swimwear
Polyester – the Leader of the Chlorine Proof Swimsuit Materials

Polyester fabric is the leading swimsuit material dominating the functional swimwear. It is one of the most durable swimwear materials proven to retain its color and shape, and resist the chemicals in the pool. This is what makes this material “resistant to chlorine”.

Polyester swimsuits keep their color for at least a year of frequent usage. These can be as much as two years, as well, for less intense usage.

Owing to resistance to sagging, polyester swimsuit features consistent fit even with frequent usage. In addition, it dries quickly. As a result, it is a popular choice for professional swimsuits and water classes.

The flaw of polyester swimsuit refers to the reduced stretch of the material resulting in a tight fit. This, in its turn, leads to sizing issues as you should consider sizing up for one or two sizes.

Nevertheless, the development of the textile industry has lead to the significant improvement of both touch and feel of the polyester. This, in its turn, has resulted in polyester excelling other materials.

Polyester can be either combined with Lycra® for an easier and better fit or just pure polyester.

Polyester PBT – Improved Chlorine Proof Polyester

Polyester PBT (Polybutylene Terephthalate) relates to the combination of polyester yarns with PBT. This material possesses the same stretch and hand-feel features as Lycra® does.

Resistance to chlorine makes PBT a superior choice for swimwear. An added benefits are its resistance to color fading and salted water.

Regardless the level of the tension, the lightweight PBT material is going to return to its shape. The material remains lightweight even when in water. It stays close to the skin. As the result, PBT is a favored choice by water athletes and swimmers.

Chlorine Resistant Swimwear
Lycra® Blends – Superior Comfort and Fit but Reduced Resistance to Chlorine

Lycra® (AKA elastane) is known for its stretch and snug fit. Swimsuits featuring Lycra® are proven to offer high-level comfort. Many customers state that wearing Lycra blend swimsuit is like wearing a “second skin”.

However, due to the elasticity, Lycra® swimsuits tend to lose their shape and color. Besides that, over time Lycra® fibers are getting destroyed by pool chemicals unless a special finish is applied.

Chlorine Resistant Swimwear

If you go to the pool several times a month, no worries – your Lycra® blend bathing suit will last long enough. Though, on condition that you take proper care of your bathing suit – involving careful rinse once out of the pool and detergent wash at home. If there happens some chlorine left in the swimsuit, it will continue to destroy the Lycra® fibers regardless of whether wet or dry.

When you notice small grains (similar to the sand) on your bathing suit, it means that the elastane fibers start breaking and it will apparently lead to sagginess and see-through effect of the fabric. This can be a result of both chemical (chlorine, other pool chemicals, sunscreens) and natural (sun and salted water) causes.

Chlorine Resistant Swimwear

If you are a more frequent pool swimmer and still wish to enjoy Lycra® benefits, you should consider either rotating several bathing suits or getting specially treated Lycra® swimsuit.

Consequently, you should look for a swimsuit featuring Xtra Life Lycra® material. These are said to last 5-10 times longer than not treated Lycra®.

Just for information – specially treated swimwear fabric with elastane can last up to 50 hours in the pool without breaking the fibers. But there are available also more durable fabrics on the market lasting up to 75 and even 100 hours.

Nevertheless, if you are a frequent pool swimmer, this is not a way to go for you. Instead, you should opt for any other type of swimwear material mentioned above.

Nylon – Great Fitting but Not Resistant to Chlorine

Nylon is amongst the most common swimsuit material choices even though it is neither resistant to chlorine nor long-lasting if compared to polyester.

It is a very lightweight, stretchy and smooth material offering a great fit. Nylon is resistant to abrasion and features low moisture absorbency. But as mentioned before, it gets destroyed by chlorine.

So if you are looking for chlorine resistant swimwear, you should stay away from Nylon swimsuits.

Chlorine Resistant Swimwear
So Which Swimwear Material to Choose?

It is all about your preferences and intended frequency of using a swimsuit.

The tensest pool-swimming activities would require polyester PBT material while pure polyester and polyester Lycra® blend would be sufficient for less frequent water activities. If you enjoy pool several times a month, any swimsuit featuring Lycra® or specially treated Lycra® would work just fine.

The next thing to consider is the fit and feel of the swimsuit. If you are a comfort and fit driven, you should consider getting polyester Lycra® blend or Lycra® material. If function and performance stand above everything else, pure polyester is the way to go. But if you wish the comfort and fit without sacrificing the performance and function, polyester PBT could be the best choice.

And then there is also such an important point as the cost of the swimsuit – the more functional and durable the swimsuit, the higher the cost. Without doubt, PBT, Polyester and specially treated Lycra® swimsuits are more expensive than Nylon and Spandex bathing suits. So it is up to you to decide whether or not it is worth it. We do believe it is.

The most important thing to remember, however, is taking proper care of your swimsuit. And don’t forget to have fun while in the water 🙂

Little Bit of The History – The Invention of Chlorine Resistant Material

Chlorine resistant fabric was first introduced at the end of 90-ties, or to be more specific, in 1994. It was done by Speedo. The material was 45% Polyester / 55% PBT. Owing to the lack of elastane in the composition of the fabric, it didn’t break after the usage in chlorinated water.

    Amazing the gadgets and products that are now available – this is super! It’s surprising that this isn’t a more widespread option for swimsuits, chlorine really does do a number on most fabrics.

    I love that there is now durable and chlorine resistant trunks – the big question is whether they are also resistant and strong when it comes to salt and sea water too?

    • Hey Kegan

      Chlorine resistant swimsuits are a life saver for many frequent swimmers in both pool and salted water. The construction and finish of the material chlorine resistant swimwear is made of is designed to hold up well against any harmful agents, starting from pool chemicals, salted water, prolonged sun exposure and ending with sunscreen lotions and body perspiration. However, proper caring for your bathing suits stands above everything else. Learn here how to wash and dry your swimsuit to extend its lifespan and retain its properties.

    Hi there. 

    This is really wonderful. I am amazed to come across this post. The resistant Swimwear is a really good innovation because this is the first time I am hearing this. I love the Polyester fabric is the best for because of its amazing features and it durability and its value for money. Thank you for this info

  3. Fasuan

    Wonderful writeup i must say, you really shed pure spotlight on the chlorine resistance swimsults and the truth behind it. I like my swimsult in nylon fabric but Nylon as you analysed is lightweight and offers a smooth fit and has its disadvantages as it is not chlorine resistant and not as long lasting as polyester, this analysis of yours really got me to know why the ones I bought doesn’t last long. This is very helpful. It’s an eye opener.

    Nice detailed options you’ve given about long lasting swimsuits. I like using nylon swimsuit because it was always easy for me to clean it up after use. I wasn’t aware there was a thing as long lasting swimsuits. I do fancy the Lycra material because of its elasticity, but don’t you think this material would be very hot especially, out of water?

    • Arta

      Hello Louis

      Thank you for visiting my website. 

      You are right – Lycra tends to hold the moisture right next to the skin and this is one of the reasons you could feel hotter. However, it is a swimsuit, covering not so big areas of your skin. Besides that, when you wear a swimsuit, you expect it to be warm/hot and you can refresh yourself any moment.

      I have had a few Lycra swimsuits and I haven’t noticed feeling hotter than usual when wearing those. So I personally believe that the advantages of Lycra swimsuit outweigh this tiny drawback that I don’t find essential – it is summer, it is hot regardless of the swimsuit material you wear 🙂

      Cheers, Arta

    I do always think there is always a need to wear chlorine resistance swimsuit when swimming.but when I think about it through again. Is not just about wearing any chlorine resistance swimsuit but it about getting the quality chlorine resistance swimsuit that last longer and better than ordinary swimsuit.

    I seems to like the lycra@ with it ability to stretch and snug fit also the style and the colour of it

  6. Gracen

    Hello Arta, it is quite interesting to know that gone are the days when bathing suit used to be boring and full o f dull colours. Reading your article has taught me one thing or more about bathing suits and the importance of choosing chlorine resistant swimsuit. At least I now know that what causes most swimsuit to fade faster is as a result of chlorine’s presence in the pool together with the effect of the sunscreen lotion and oil or cream.I love polyester fabric materials, but I haven’t quite used the material when it comes to swimming, however with this review, I now know what to look out for while purchasing swimming suit. The Polyester PBT is great with lots of improved features, especially its resistance to color fading and salted water.

  7. Gomer

    Summer is indeed approaching and I’m sure my girlfriend who love going out to beach would love having one of these that are in your list. Here in our place, people prefer swimming out the the sea instead of swimming in a chlorinated pool. 

    Before I buy any of these items, I’d like to know what is the recommended cleaning or washing method of these after usage? My girlfriend is a grade school teacher and is a very busy person, so her only way to wash clothing like these is by using a washing machine. Is it okay to wash a swimwear in a spinner or washing machine?

    • Arta

      Hey Gomer

      I hope your girlfriend will find her perfect swimsuit. Please have a look at instructions on how to properly care for your swimsuit to elongate its life spun here.

      If any questions, PLS let me know.

      Hope this helps!

    Just like all of your blog posts, this has been very educative too. I am sure a lot of women would love to stop by here every now and then.

    However, you said that the deterioration of the suits  is accelerated when pool water comes in contact with sunscreen oil or cream. Does this mean ladies should not use sunscreen whenever they want to go to the pool side on a sunny day? Or is there a special cream that has the radiation adsorption power of sunscreen lotions and at the same time, doesn’t react with the suits?

    • Arta

      Hey there

      Thank you for visiting my website and I am glad you have found my article about Chlorine resistant swimwear educative.

      To answer your question about sunscreen and its effect on the swimsuit, I would suggest you read my article about how to remove sunscreen here. Not only the article explains how to remove the sunscreen stains, but it also advises how to avoid them.

      Cheers, Arta

    I remember having a pair of swimming trunks that had very small white pieces of fluff on its surface. At the time, I wondered what was causing it and now you have explained clearly and concisely.

    Am I right in saying that the more polyester and PBT that is woven into the fabric, the more chlorine-resistant the swimsuit is?  

    • Arta

      Hey Paul

      Thank you for visiting my website and taking the time to leave a comment. In simple words, you are right. Polyester PBT is a superior choice of material for Chlorine Resistant swimwear followed by polyester swimsuit – so if you are looking for a chlorine resistant swimsuit you should look for these 2 materials.

      Happy summer, Arta

  10. Sherry

    I didn’t know there was such a thing! Thank you for sharing. I am definitely very much interested in chlorine resistant swimwear now! My only concern as a health conscious person is does the material or process to make the material used pose any dangers? Are there any harmful chemicals used? 

    • Arta

      Hey Sherry

      Chemicals are quite common in the textile industry, so the main thing to worry about is whether or not these chemicals are within the allowances as any excess can expose your health to danger. The safest way to make sure of this is to look for swimsuits made of certified materials  – both Oeko Tex and Bluesign certificates ensure that the chemicals are within the allowances posing no threat to your health.

      Happy shopping, Arta

  11. Alblue

    While swimming, I tend to forget about the chlorine effect in the pool. Thank you for recommending some nice chlorine resistant swimwear. My sister loves Lycra so she will definitely buy it the moment we hit the store. Now it’s my turn to find the guy’s version. Oh, do you know if this type of swimwear also available for kids? Thanks for your information

    • Arta

      Hey there

      Thank you for taking the time to leave your comment. Chlorine resistant swimwear is available also for kids, you just need to pay attention to the material of the swimsuit or look for the relevant information on the hangtag added to it – usually, suchlike information is available.

      Cheers, Arta

  12. George

    Well one of my siblings used to swim and chlorine has caused him problems. Too bad i didn’t know so i could tell him.

    Well Polyester PBT is the most chlorine resistant material but as usual there are disadvantages. I think for people who just go in the sea in the summer should go for the Lycra or Xtra Life Lycra(I guess the Xtra Life Lycra also costs more).

    Even though i don’t swim at all i found this article informative. It doesn’t matter that i don’t swim(now), i might in the future! Cheers.

  13. Igor

    Hi Arta!

    I came across your article about Chlorine Resistant Swimwear and I can say it is a very interesting one. Knowing that clothing can be very important, or it is actually important in many fields of human’s action, it is easy for me the understand the value of having a proper swimwear as well.

    Especially is sweating is considered as a competitive sport, the importance of having the right swimwear is even bigger!

    Thanks for sharing this informative post, and I am glad to get some useful information.

    Much success,

  14. Paul

    Good Day, Arta.

    Am I correct in assuming that these swimsuits are mostly for pool swimmers?

    Are these materials affected the same way when used for lake or ocean swimming? 

    Your post features adult models, which leads me to wonder if these considerations and fabrics apply to children’s swimsuits as well. Today’s sports clothing industry has become so technical that it’s not always easy to keep up to the many changes taking place in it.

    I like how you classify and breakdown these different materials. I have found this information very useful and will forward it to my better half.

    Thanks, Paul

    • Arta

      Hello, Paul!

      Thank you for visiting my website and leaving your comment. Actually, chlorine resistant swimsuits are a good choice not only for pool swimmers but also for people loving to swim a lot (also in salted water) and people wishing to have a bathing suit for a longer time as chlorine resistant swimsuits serve longer.

      It refers also to children swimwear though they tend to grow so fast that maybe it is not necessary to spend more on a bathing suit resistant to chlorine as you will need to get a bigger size for him/her soon anyway 🙂

      Hope this helps, Arta

  15. Carmen

    I am about to buy a new swimsuit and I found on your site, I say I was lucky. I postponed the purchase just because I didn’t know what textile material to buy. Polyester PBT seems the best fit for me, because I only swim in the sea. Thanks for sharing.

  16. Claudio

    I am just looking for chlorine-resistant swimsuits that are durable. I have my two daughters aged 20 and 25 who regularly attend swimming at a club in the area. 

    For what you explain we have different materials I would choose the polyester combined with Lycra. I will thank you for giving me your opinion and what models will you recommend me?

    Thank you!

    • Arta

      Hey Claudio

      Thank you for your comment.

      Polyester combined with Lycra is a great choice as it is both durability and comfort. So I am sure it will be suitable for your daughters in a long term.

      Cheers, Arta

  17. Shan

    What an interesting article; I really enjoyed reading it! I never gave much thought to what effects mixing sunscreen and/or oils and chlorine might have on the longevity of my swimwear. In fact, I never gave much thought to the fabric choice of my swimsuits beyond style and functionality.

    Thanks to your extra details, I know to keep these factors in mind in the future when purchasing swim wear. I am now curious to check all the swim wear I own to see what types of material they are made from. Do you have any personal preferences (lycra, nylon or polyester) when it comes to your swimwear? Thanks so much for your input and advice!

    • Arta

      Hey Shan

      Thank you for your comment! 

      I personally prefer Lycra been bathing suits due to its comfort and great fit. Though it means I need to change the bathing suits more often – but this is also as a benefit in my eyes – if price is affordable, it just means I am having a new swimsuit for each season or once in a two seasons – isn’t it great? 🙂

      Cheers, Arta

    Thanks again and keep in touch!

  22. Christine

    This is a very interesting post. I like polyester and I didn’t know that it was chlorine resistant material, and it does indeed dry quickly, which is another nice extra. I have not heard of polyester PBT, it’s great that they are resistant to salty water, because I really love swimming in the ocean, and the salt water can be rough on clothes. 

    I learned so much in this article. I used to buy swim suits or bikinis, never much thinking of the material and if it was salty resistant or chlorine resistant. The next time I buy a bikini or swimsuit I will definitely pay more attention to those details. Do you think that Speedo is the best brand or are there any other brands that you recommend?

    Thanks for sharing this information!

    Hey, Your swim suit guide very useful for everyone. Now I know from your article that Chlorine resistant swimsuits are stated to last even 20 times longer than regular bathing suits. Your step by step guide for choosing the best fabric is very awesome for everyone. You are doing grate work for swimmers to find the best swim suit. Keep the grate work up.

  25. Rhain

    It would be certainly wonderful to find a durable swimsuit and I really would not mind if it also has a touch of style. It is very surprising to find that these Chlorine resistance swimsuits actually lasts longer than their average counterpart. The lycra blend are simply awesome and appears truly appealing. I’m so glad I found this. Thanks

  26. Steve

    Finding chlorine resistant fabric for my wife’s swimsuits has been a thorn in our side for years now. Not much is more frustrating than spending a good amount of money on a nice swimsuit only to have it ruined after only a season or two of even infrequent wear. Thanks for this post that shares some really great ideas about the different types of fabrics and their chlorine resistance. I will have to remember to refer back when it comes time to purchase another swimsuit!

  27. Feochadan

    I had NO idea that chlorine could deteriorate a lycra bathing suit like that – even when dry!  Your article was a real eye-opener to me.  Fortunately, I do not swim much but I will be looking after my swim gear much better now by rinsing it at the pool and then giving it a good wash with detergent when I get home.  Now you having me running to my closet to see what my bathing suits are made of!

  28. fyre

    I can’t believe I’ve never heard of PBT swimwear before your article!  I know I have some treated Lycra tankinis but, they all still seem to lose their shape and fit pretty quickly.  In their defense, I do have a tendency to wear things hard and, my swimwear is no exception.  

    Thanks to you I will be diversifying my swimwear this season.  It sounds like PBT will hold up well to my aqua-aerobics as well! 

  29. Bella

    Hello there, my daughter have told me about such swimming suits but I felt like she wasn’t really serious and I didn’t give much attention to it. Getting to see these swimming suits makes me amazed about these thing and I see reasons why I should get some for myself rather than the regular ones whose fabrics are not good enough. Thanks for the article.
