How they differentiate from each other

Since we’ve covered the most well-known and popularized materials out there for creating a vast majority of swimsuits, we can now start reviewing each and every type of swimsuit fabric individually.

How they compare to each other and how they differ when it comes to quality and other key features out there, and what really is the best type of swimsuit. Let’s review each and every swimsuit fabric:


Polyester is the most well-known and used type of fabric when it comes to the production of swimsuit articles. It has been around for ages as it is the most practical and versatile type of fabric out there. Why is this the case?

Polyester is specifically known for its many qualities such as being extremely comfortable when worn, extremely durable can resist any sort of potential rips and tears, it dries off quickly meaning that you will have your swimsuit ready for wearing in no time. It’s an extremely breathable and flexible material, which means that you will find extreme comfort in this material.


Nylon is mostly known as the greatest alternative for polyester when it comes to shopping for similar quality swimwear as polyester-made garments. It possesses many similar features to polyester, but also lacks many, making it a clear substitute when it comes to buying swimwear.

It is very flexible and extremely comfortable, however, it does not dry out as quickly as nylon does, so you may have difficulty drying your swimwear. Also make sure you read the blog about whether nylon can be bleached.

Polybutylene or PBT for short

This type of fabric material is only used in a very rare production of swimwear, as it is not one of the most desirable types of fabric to be used in regard to swimwear. However, it does possess some very interesting traits that may make you consider using it as an alternative.

PBT-type of swimwear is very fast drying, meaning you will be able to have dry clothes within a few hours, they also have a very specific outer glow to them which will easily make them recognizable. They’re most well-known for their resistance to chlorine damage, making them a great and long-lasting alternative if you are worried about having your clothes stained by chlorine

Concluding the Best Option

Although all of these fabrics are very versatile and extremely different from each other, there is one fabric that by far outweighs most of these fabrics overall. If you are looking for the best swimwear fabric out there when it comes to having great durability which will last you for ages, being extremely fast drying, providing you with some of the best comforts out there, as well as being extremely flexible, then the best choice would be any polyester type of fabric.

The wide variety of features that polyester has to offer is the main reason why this fabric is so popular. With its popularization, comfort, and availability, owning any sort of polyester swimwear is the best choice. If you are unable to find any sort of polyester-made swimwear, nylon will serve as a very great alternative with lessened features to it.

Nylon is mostly known to be used as a great substitute. Even though it is considered simply an alternative, it still works great.
