Fleece vs. Polyester – Is Polyester Warmer than Fleece?

Last Updated on December 6, 2022

Fleece vs. Polyester: Is Polyester Warmer than Fleece? However, in terms of warmth, polyester is warm and also fleece are effective at trapping heat. But fleece is comparatively less warm than polyester because it allows your skin to breathe more easily. It means you are less likely to feel sweaty and uncomfortable while wearing fleece, which can make a big difference on cold days.

Fleece vs. Polyester – Is Polyester the Same as Fleece?

s Polyester Warmer than Fleece

Polyester and fleece are different because polyester is an artificial fiber while fleece is wool. Polyester is made from petroleum and synthetic fibers, which makes it cheaper than wool. Polyester can be more durable than fleece because it doesn’t absorb water, but fleece can be more breathable.

What Are the Pros and Cons of Polyester?

Polyester for home textiles is a dense, thin, and even fiber.


Polyester Pros:

  • Smooth
  • Thin
  • Lasting
  • Serves for a long time
  • The dye lays down evenly, brightly
  • Does not stretch during washing and spinning
  • Dries quickly
  • Not covered with pellets
  • Inexpensive
  • Does not burn out

Polyester Cons:

Why Did Polyethylene Never Replace Natural Raw Materials? Compared to cotton, linen, and silk, it:

  • Less soft
  • Does not pass air
  • Does not absorb moisture
  • Cools the skin
  • Electrified

Many people complain that the skin itches when synthetics are in contact with the skin for a long time. Therefore, 100% Polyethylene for underwear or bed linen is practically not used.

What Are the Pros and Cons of Fleece Fabric?

Fleece Pros 

  • Durability is subject to compliance with production technologies
  • Good thermal insulation even when the fabric is wet
  • It allows the body to breathe and does not create a greenhouse effect
  • Strength and lightness.

Fleece Cons

  • Only one can be distinguished
  • It can be electrified
  • As a result of which it attracts dust.
  • However, you can avoid this by purchasing high-quality items.
  • They have been treated to prevent static electricity from accumulating in the fabric.

Polyester vs. Fleece: What is the Main Difference?

Fleece is a type of wadding that is made from synthetic fibers. It is soft and warm and traps air close to the skin. Fleece can be found in many different types of clothing, such as jackets, fleece, hats, socks, and more.

Fleece vs. Polyester

Polyester is a synthetic fiber that is created by extruding a polymer through spinnerets into the form of filaments. These filaments are then joined to form a continuous thread or yarn. 

Polyester fabrics are popular in clothing because they are lightweight and simple to care for. They also resist wrinkling, shrinking, abrasion and mildew because they don’t absorb moisture well.

The main difference between polyester and fleece is that polyester is best suited for summer and winter clothing, undergarments, or merely the top ball of a product, whereas fleece is utilized for warm products.

We frequently consider the fabric used when selecting clothing for ourselves. It is significant because nobody wants to wear anything uncomfortable. But even though they are synthetic, polyester and fleece are renowned for their coziness and use.

Is Polyester Warmer than Fleece?

The answer is Yes, Polyester is Warmer than Fleece. Therefore, polyester is often used in winter clothing because it is a synthetic fabric that is effective at trapping heat. 

Is Polyester Warmer than Fleece?

First, let’s look at the properties of fleece. Fleece is made of synthetic fibers, so it does not absorb water or retain heat like natural fibers like wool or cotton. It also has lower thermal conductivity than natural fibers, which means it does not retain heat as well.

On the other hand, polyester is an artificial fiber made from petroleum and natural gas byproducts. It has a higher thermal conductivity than fleece because of its density and thickness, which means it retains heat better and can be warmer in cold climates. Polyester also absorbs water more easily than fleece because it retains moisture and releases it when dry again. Polyester is warmer than fleece because it traps air better.

Why Does Polyester Feel So Warm?

Polyester is a synthetic material, i.e., in nature, such material does not exist. People synthesized it. Polyester can be different, depending on which polyester fabrics we are talking about.

Why Does Polyester Feel So Warm?

Whether it is warm or not depends on the structure of the thread, weaving, and so on. If the material has an air gap or something similar, then the material will be warm (for example, fleece material, in which an air gap is created due to the pile, or heaters in jackets are made so that there is a lot of air space.) Air is a poor heat conductor, so heat saves a person, and a person does not freeze.

Why Fleece is Better for Cold Weather Clothing?

Fleece is a type of synthetic material that can be made from different fibers. It is often used in clothing because it is lightweight, soft, warm, and breathable. Fleece has been popularized in jackets, sweaters, hats, and gloves.

Why Fleece is Better for Cold Weather Clothing?

The word fleece comes from the Old English word which means to strip off wool or hair by pulling it with the fingers or shears. This definition fits well with the material’s original use as animal skin for warmth and protection.

How to Store and Care for Polyester and Fleece Items?

Polyester and fleece items are some of the most versatile pieces in your wardrobe. They can be dressed up or down, depending on the occasion. However, caring for them properly is essential to maintaining their quality. Here are some tips on how to store and care for your polyester and fleece items

 Polyester and Fleece

How to Care for Fleece Fabrics

You can store fleece clothing on a coat hanger, even when folded. It is impossible to iron the fleece since already at 60° C, the polyester fibers begin to melt, and the fleece completely loses its quality. Fleece items can be washed in warm, but not hot water, using a liquid detergent.

Too hot water can permanently damage the fabric. Twisting is strictly prohibited. You need to wring out the thing with your hands to get rid of the main part of the water, then hang it on a rope or lay it out on a dryer. Fleece dries quickly, so no additional drying equipment is required.

How to Care for Polyester Fabrics

Synthetic and blended fabrics are easy to care for, but one limitation is high temperatures. Polyester should not be boiled or ironed at high temperatures – this can permanently ruin things. In addition, when washing, adding a rinse aid with an antistatic agent is recommended. It will help to partially eliminate the property of artificial fibers to accumulate static electricity. 

 Polyester Fabrics

The most critical requirement: avoid exposure to high temperatures. With short-term contact and moderate heat, wrinkles appear, and from an iron set to steam or any indelicate mode, polyester shrinks and melts. Polyester is highly electrified and should not be ironed or bleached. 

To maintain a presentable appearance, wash clothes at 30-45 degrees and without using chlorine-containing products. The spin should go with a minimum number of revolutions, and immediately after the end of the wash, things should be straightened and hung up. If you do everything right, the urgent need for ironing will disappear. 


It’s a common question: is polyester warm? warmer than fleece? As both polyester and fleece are great insulators, the answer, unfortunately, is more complex. It depends on the type of fabric, the weight of the fabric, and how the fabric is constructed. For example, a heavyweight polyester fabric will be warmer than a lightweight fleece fabric. And a tightly woven polyester fabric will be warmer than a loosely woven one.
