Yes, polyester can get wet. The degree of wetness or water seeping into the fabric depends on the fabric’s thickness and the number of threads used.


It turns out that it is pretty resistant to water. Being water resistant means the way the material is constructed is highly dense.

The denser a fabric is, the less water seeps in and, therefore, the drier you’ll stay. It’s simple logic: The fewer holes something has, no matter how small, the more resistant it is to water damage.

Polyester-resistant and is one of the most water-resistant fabrics out there.

It’s often used in sportswear because it wicks moisture away from the body, keeping athletes comfortable and dry.

So, if you’re ever in a situation where you need to get wet but don’t want your clothes to suffer for it, reach for the polyester!

It is also considered “everyday waterproof,” which means. However, it’s not 100% waterproof; it is protective enough for most everyday situations, such as being out in rain or snow, but not completely submerged under water for a prolonged period.

Polyester itself, strand by strand, is waterproof. It’s a material that is very unlikely to absorb moisture. And it’s a material that can be woven quite tightly to help stop moisture from seeping in.

However, it is not 100% waterproof. It depends on the number of threads used and the density. More threads or treatment with water repellents equal more waterproof abilities. 

The Difference between Water-resistant and Waterproof

Water-resistant fabric can resist some amount of moisture but is not entirely waterproof.

Waterproof fabric can withstand complete submersion in water and will not allow any moisture to pass through.

So, while it can be considered water-resistant, it may not necessarily be 100% waterproof.


Polyester is commonly used in clothing, upholstery, and outdoor equipment. It’s also often blended with other fabrics to add durability and wrinkle resistance.

Some specific uses include sports clothing, camping gear, pillows and cushions, and carpeting.

It’s water-resistant properties make it a go-to choice for outdoor gear and sports clothing, while its wrinkle-resistant qualities make it popular in upholstery and clothing.

  • It is a durable fabric and can handle regular washing, but it’s essential to follow the care instructions on each garment.
  • Polyester is prone to shrinking when exposed to high heat, so wash them in cool water and avoid putting the clothes in the dryer.
  • To keep them looking their best, consider using a fabric softener and hang or lay flat to dry.

So, now you know the truth: yes, it can get wet! And not only that, but its water-resistant properties make it an excellent choice for those seeking durable and practical fabrics.

So, when in doubt, reach for the polyester!
