Welcome to an article all about the different types of waterproof polyester! Whether you’re looking for a rain jacket, tent, or backpack that can withstand the elements, it’s important to know which type of polyester is best suited for your needs. In this article, we’ll explore the various types of waterproof polyester and how they can provide protection in wet conditions. Whether you’re an outdoor enthusiast or just looking to stay dry during a rainy day, understanding the different types of waterproof polyester will help you make the right choice for your next purchase.

What Type Of Polyester Is Waterproof?

Have you ever wondered what type of polyester is actually waterproof? With so many different types of polyester fabrics on the market, it can be confusing to know which ones will keep you dry in wet weather conditions. In this article, we will break down the different types of waterproof polyester fabrics and guide you on how to choose the best one for your needs.

Types of Waterproof Polyester Fabrics

1. Polyester Laminate

Polyester laminate is a popular choice for waterproof fabrics. It is created by bonding a waterproof membrane to the polyester fabric, which prevents water from seeping through. This type of polyester is often used in rain jackets, tents, and other outdoor gear. The laminate can vary in thickness, with thicker laminates offering increased waterproofing capabilities.

2. PU Coated Polyester

Polyurethane (PU) coated polyester is another common waterproof fabric. In this process, the polyester fabric is coated with a layer of polyurethane, which creates a barrier against water penetration. PU coated polyester is lightweight and flexible, making it a great choice for raincoats and windbreakers.

3. PTFE Coated Polyester

Polytetrafluoroethylene (PTFE) coated polyester is a high-performance waterproof fabric that is known for its durability and breathability. PTFE is a synthetic polymer that is non-stick and water-resistant, making it an ideal choice for outdoor gear such as tents and backpacks. This type of polyester is also resistant to stains and chemicals, making it a versatile option for outdoor enthusiasts.

4. EPTFE Membrane

Expanded polytetrafluoroethylene (EPTFE) membrane is a waterproof fabric that offers excellent breathability and waterproofing capabilities. This type of polyester is made up of a microporous membrane that allows moisture vapor to escape while preventing water from entering. EPTFE membranes are commonly used in high-end outdoor gear such as hiking boots and gloves.

Choosing the Best Waterproof Polyester Fabric

When selecting a waterproof polyester fabric, there are several factors to consider to ensure you choose the best option for your needs:

1. Waterproof Rating

The waterproof rating of a polyester fabric is measured in millimeters and indicates how much water pressure the fabric can withstand before leaking. A higher waterproof rating means the fabric is more resistant to water penetration. Be sure to check the waterproof rating of the polyester fabric before making a purchase.

2. Breathability

Breathability is an important factor to consider when choosing a waterproof polyester fabric. Fabrics that are highly waterproof but lack breathability can trap moisture inside, leading to discomfort and clamminess. Look for fabrics with breathable membranes that allow moisture vapor to escape while keeping you dry.

3. Durability

Durability is key when selecting a waterproof polyester fabric, especially if you plan to use it for outdoor activities. Choose a fabric that is abrasion-resistant, tear-resistant, and able to withstand harsh weather conditions. A durable fabric will last longer and provide better protection against the elements.

4. Weight

The weight of the polyester fabric is another important consideration, especially if you are looking for lightweight outdoor gear. Lightweight fabrics are easier to carry and pack, making them ideal for activities such as hiking and backpacking. Consider the weight of the fabric when choosing a waterproof polyester for your needs.

5. Cost

Cost is always a factor to consider when purchasing outdoor gear, including waterproof polyester fabrics. While high-performance fabrics may come at a higher price point, they often offer superior waterproofing capabilities and durability. Invest in a quality waterproof polyester fabric that meets your needs and budget.

Care and Maintenance Tips for Waterproof Polyester

Proper care and maintenance of waterproof polyester fabrics are essential to ensure their longevity and performance. Here are some tips to help you keep your waterproof polyester gear in top condition:

1. Cleaning

Regularly clean your waterproof polyester gear to remove dirt, debris, and stains that can compromise the fabric’s waterproofing abilities. Use a mild detergent and a soft brush to gently scrub the fabric, then rinse thoroughly with water and allow it to air dry.

2. Waterproofing

Over time, the waterproof coating on polyester fabrics can wear off, leading to decreased waterproofing capabilities. Reapply a waterproofing treatment to your gear as needed to restore its water resistance and protect it from the elements. Follow the manufacturer’s instructions for the best results.

3. Storage

Store your waterproof polyester gear in a cool, dry place away from direct sunlight and moisture. Avoid folding or compressing the fabric for extended periods, as this can damage the waterproof coating. Hang or lay the gear flat to maintain its shape and integrity.

4. Repairs

If your waterproof polyester gear becomes damaged or develops leaks, repair it promptly to prevent further damage. Patch tears or holes with a waterproof patch or sealant, following the manufacturer’s instructions carefully. Regular maintenance and repairs will prolong the life of your outdoor gear.


In conclusion, choosing the right type of waterproof polyester fabric is essential for staying dry and comfortable in wet weather conditions. Whether you opt for a polyester laminate, PU coated polyester, PTFE coated polyester, or EPTFE membrane, consider factors such as waterproof rating, breathability, durability, weight, and cost when making your selection. Proper care and maintenance of your waterproof polyester gear will ensure its longevity and performance, allowing you to enjoy the great outdoors in style.
