Polyester is a great fabric for swimming. It is chlorine-resistant, quick-drying, durable, and retains its shape and color. That being said, polyester swimwear is a reliable and long-lasting choice for both recreational and competitive swimmers.
In this article, I will delve into the reasons why polyester is a good option for swimming and a few considerations to keep in mind.
Advantages of Swimming in Polyester

Polyester is a synthetic fabric known for its versatility and strength. In swimwear, polyester offers several desirable properties that make it suitable for swimming:
1. Chlorine resistant
One of the significant advantages of polyester is its excellent resistance to chlorine. Chlorine is commonly used in swimming pools as a disinfectant, but it can be harsh on swimwear fabrics.
Polyester stands up well to chlorine exposure, making it a durable choice for regular pool swimming. It retains its shape, color, and elasticity even after prolonged exposure to chlorine-treated water.
2. It dries quickly
Polyester is a hydrophobic fabric, meaning it repels water. This property allows swimwear made from polyester to dry quickly once you’re out of the water. Compared to other fabrics like cotton, which tends to absorb water and stay damp, polyester keeps you comfortable by shedding moisture and drying rapidly.
3. It is resistant to wear and tear
Polyester is a strong and durable fabric, making swimwear resistant to wear and tear. It can withstand frequent use, extended exposure to sunlight, and the repetitive motions of swimming. This durability ensures that your swimwear lasts for a long time, making polyester a cost-effective choice in the long run.
4. Shape retention
Polyester has excellent shape retention, meaning it maintains its original form even after repeated stretching or exposure to water. This property is crucial for swimwear as it ensures a snug and comfortable fit, allowing freedom of movement without the worry of sagging or stretching out over time.
5. Colorfastness
Polyester fabrics have good colorfastness, meaning they retain their vibrant colors even after exposure to sunlight, chlorine, and washing. This makes polyester swimwear a great option for those looking for long-lasting, fade-resistant designs that maintain their visual appeal over time.
Potential Drawbacks of Swimming in Polyester Swimwear
1. Breathability
While polyester is a fantastic fabric in terms of durability and quick drying, it may not be the most breathable option. Polyester does not have the same level of breathability as natural fibers like cotton or bamboo.
However, advancements in fabric technology have led to the development of moisture-wicking polyester blends that enhance breathability and comfort.
2. Fit and comfort
When selecting polyester swimwear, it’s essential to consider the fit and comfort level. Look for swimwear with features like adjustable straps, elastic waistbands, and proper lining to ensure a comfortable and secure fit. Trying on different styles and cuts of swimwear can help determine the best fit for your body type and preferences.
3. Heat retention
Polyester swimwear may retain heat more than some other fabrics. This can be an advantage in cooler water or colder weather, as it helps to keep the body warm during swimming. However, in hot or tropical climates, it’s worth considering swimwear with mesh panels or ventilation features to enhance breathability and prevent overheating.
Maintenance and Care Tips for Polyester Swimwear
Below are some valuable tips on how to care for your polyester swimwear and extend its lifespan properly;
1. Rinse after each use
After a day at the beach or the pool, it’s crucial to rinse your polyester swimwear thoroughly. Rinse it in cool, clean water to remove any sand, salt, or chlorine residue. Gently squeeze out the excess water, but avoid wringing or twisting the fabric, as this can damage the fibers. Rinse as soon as possible after wearing to prevent any stains or discoloration from setting in.
2. Hand wash with mild detergent
Polyester swimwear is best hand washed to maintain its shape and quality. Fill a basin with cool water and add a small amount of mild detergent specifically designed for delicate fabrics. Avoid using harsh soaps or bleach, as they can damage the fabric. Gently swish the swimwear in the soapy water, paying attention to any stains or spots. Let it soak for a few minutes, and then rinse it with clean water until no soap remains.
3. Do not machine wash or dry
It’s important to note that machine washing and drying can be too harsh for polyester swimwear. The agitation and high heat of the machine can cause the fabric to stretch, fade, or lose its shape. Always opt for hand washing instead to maintain the integrity of the swimwear. Additionally, avoid using a dryer as it can damage the fibers and lead to shrinkage or deformation. Instead, lay the swimwear flat on a towel to air dry in a shaded area.
4. Avoid rough surfaces and friction
To prevent pilling or snags, be cautious when sitting or lying on rough surfaces while wearing your polyester swimwear. Avoid sitting on concrete or rough pool edges, as they can cause abrasion and damage to the fabric. When wearing a cover-up or beach towel, make sure it is soft and clean to avoid any friction against the swimwear.
5. Store properly when not in use
Proper storage is crucial in maintaining the quality of your polyester swimwear. Once your swimwear is completely dry, fold it neatly and store it in a cool, dry place away from direct sunlight. Avoid placing it in plastic bags or airtight containers, as they can trap moisture and lead to mold or mildew growth. Instead, use a breathable fabric bag or hang it on a padded hanger to preserve its shape.
What fabric is best for swimming?
Polyester is one of the best fabrics for swimming due to its chlorine resistance, quick-drying properties, and durability.
Which is better for swimming nylon or polyester?
Polyester is generally considered better for swimming than nylon due to its superior chlorine resistance, quick-drying capabilities, and durability.
Conclusion
Polyester is a versatile and reliable fabric for swimwear, offering durability, chlorine resistance, quick drying, shape retention, and colorfastness. While it may not be the most breathable option, advancements in fabric technology have addressed this concern with moisture-wicking blends. When choosing polyester swimwear, consider factors such as fit, comfort, and climate to ensure the best experience.
