Both Nylon (also known as Polyamide) and Polyester are superb fabric choices for swimwear as both are “tough" materials that can withstand the heavy use of constant body movements. Both materials are resistant to shrinkage, which of course is a must for apparel we use in water most, if not all the time.
Nylon and Polyester are synthetic fabrics, meaning they are manufactured.
Here are some other features of the fabrics. It might help you decide which swimwear to buy.
: Both Nylon and Polyester have low moisture absorbency, so you won't feel the swimwear weighing on you after your dip. However, Nylon has much less (some articles say zero) absorbency than Polyester. It also means that Nylon-made swimwear dries quicker than a Polyester-made one.
: Nylon has a better stretch than Polyester, so it gives a "less tightness" feel on the body, and the swimwear is easier to put on (than a Polyester made one). However, more stretch may also mean that the swimwear will lose its shape quicker than the one with less stretch.
: Polyester has better resistance to chlorine than Nylon. Your swimwear will have less fade in its colors over time if it is more chlorine resistant.
: Polyester has better sun exposure resistance than Nylon. With this property, you worry less about your swimwear thinning out with use.
