Polyester is probably the most common fabric for bags, tents, and outdoor gear. What is the 600d Polyester fabric? Is it really waterproof?

Polyester is a synthetic fiber, a polymer derived from recycled and waste materials or from bacterial fermentation. This material is often chosen because of its natural water-repellency, elasticity, and durability.

Polyester is not eco-friendly, even if there is some biodegradable polyester the majority of the polyester on the market is not biodegradable, being in part derived from petrol.

It is often blended with cotton to improve its durability and wrinkling profile. In fact, polyester fabric is very resistant to weather conditions, which is why it is the first choice for outdoor products such as panniers, backpacks, bikepacking bags, jackets, and clothes.


What does D mean in polyester 600D fabrics?


When you read 600d, that number refers to the number of deniers used for the evaluation of nylon, silk, polyester, and other fibers, it is a unit for measuring the weight and thickness of a single thread used in a fabric. The higher the number of deniers the stronger the fiber.


Benefits of Polyester 600D


We can summarize the benefits of polyester 600d as follows:

  • It is ideal for backpacks, luggage, and outdoor gear
  • It is a strong and very durable material
  • It is an easy fiber to produce.
  • It is resistant to wrinkles.
  • Highly resistant to stretching.
  • It can be mixed with other materials.
  • Excellent resistance to atmospheric agents and temperature variations.
  • Polyester is cheaper than other materials.

The Abrasion Resistance of 600D Polyester


Another important indicator of the quality of a fabric is its abrasion resistance.

We can say, generally speaking, that polyester 600d is able to hold well even after 25,600 cycles which means that it will last for years.


Is 600D Polyester Waterproof?


Polyester is waterproof by nature, this is due to its homogeneity and continuity, which make the migration of water molecules through its fiber slow and difficult.

However, its water resistance reaches very high levels after undergoing a process called PU (Polyurethane) coating. The purpose of this process is to protect the polyester and prevent water from entering the fiber.

Nevertheless, when going shopping for items made out of 600D PVC, make sure you check out the label as well – to confirm the waterproof features.
