High-quality polyester is produced on the latest equipment and can compete with natural materials. Clothing filled with polyester is relevant both in bad autumn weather and in cold winter.

Features of Modern polyester

More recently, it was believed that clothing with synthetic insulation is in many ways inferior to products made from natural materials. Consumer skepticism was well founded. After all, the polyester produced in the past was easily wrinkled and caked, causing the product to lose shape. 

In addition, the insulation quickly lost its thermal insulation qualities, and after the first wash, the thing completely fell into disrepair.

The material’s structure explained the material’s low quality and the insulation’s inability to meet its intended purpose.

  • In the past, polyester fiber was produced as straight threads and placed in the same plane.
  • Now polyester consists of fibers twisted into spirals, balls, and tubes, inside which are air pockets.

Modern polyester is a light and warm material that perfectly copes with the role of insulation for demi-season and winter clothes.

Is polyester good for winter?

Polyester can be good for winter, depending on the specific garment and its construction. Polyester is a synthetic material that is often used in winter clothing due to its ability to retain heat and provide insulation.

However, it is important to note that not all polyester is created equal. Look for garments made with high-quality polyester blends or with additional insulation layers for maximum warmth.

It is also important to consider the breathability and moisture-wicking properties of the garment to ensure that you stay comfortable and dry during physical activity in cold weather.

Can we wear polyester in winter?

Yes, you can wear polyester in winter. Polyester is a synthetic fabric known for its durability, easy maintenance, and resistance to wrinkles and shrinking. It is also a good choice for winter wear as it is lightweight, breathable, and retains heat well. However, it is important to note that not all polyester fabrics are created equal.

Some types of polyester may not provide enough warmth for extremely cold temperatures, so it is best to check the fabric weight and insulation properties before choosing polyester clothing for winter wear. Layering polyester clothing with other warm and insulating materials like wool or down can help you stay comfortable and cozy in cold weather.

Is polyester cold in winter?

Polyester is not typically warm or cold on its own, but rather it depends on the thickness and insulation of the polyester fabric. Mainly, thicker and more insulated polyester fabrics can provide warmth in the winter, while thinner and less insulated polyester fabrics may not.

Also, wearing layers underneath or on top of polyester clothing can also help to provide warmth in the winter. So, it’s important to consider the specific type and quality of the polyester fabric in question when determining its suitability for cold weather wear.

Advantages and disadvantages of polyester insulation

The properties of polyester, its numerous advantages, and some disadvantages are due to the structure of the polyester fiber, the method of weaving threads, and various additives. Here is a list of the main positive qualities of a heater created from this material:


  • Outerwear, insulated with polyester, can serve at air temperatures from -5 ° C to -30 ° C.
  • Synthetic filler does not contribute to the emergence and development of pathogenic microflora, so people with allergies can wear things with polyester.
  • The unique formula of polyester fiber allows the product to retain its original shape for a long time. Things do not deform even after frequent washing.
  • Polyester-filled clothing does not require special care. It is easily machine and hand washable.
  • Coats and jackets filled with polyester fiber are lightweight. Adults will be comfortable in such clothing, but children will require some consideration.


Speaking about the shortcomings of this material, the following should be noted:

  • When heated to temperatures above +40 °C, the filler may deform.
  • Cheap types of material fall off after several washes and form lumps.
  • Clothes are not breathable.
  • The insulation can be destroyed by gasoline, acetone, benzene, and other aggressive chemicals.

In manufacturing high-quality polyester filler, the thermal method is usually used to connect the layers. However, gluing with special adhesives is acceptable in the production of some cheap varieties of this material, such as synthetic winterizer.

Such fillers are hazardous to health, as they can provoke allergic reactions. When choosing clothes with synthetic filler, you need to pay attention not only to the thickness of the lining but also to the method of manufacturing the insulation.

Variety of polyester insulation for Winter

When choosing clothes with a filler, each buyer is guided by the season when he intends to wear a new thing, the climatic conditions in which he lives, and, of course, the characteristics of his body. However, before going to the store, it would be useful to familiarize yourself with the properties of the most common polyester insulation on sale.

1. Thinsulate

Of all the insulations made from polyester fiber, Thinsulate is the lightest and warmest. No wonder it is compared with natural swan down.

Thinsulate, consisting of microscopic fibers surrounded by an air shell, is able to retain heat and warm the human body at a frost of -60 ° C. Moreover, the insulation is not too thick, and the clothes are light and not bulky.

This material is used to make warm clothes for polar explorers and oil workers and sew comfortable equipment for climbers. The only drawback of clothes filled with Thinsulate is the high cost.

2. Holofiber

This type of synthetic insulation is a non-woven polyester fiber made in the form of balls or springs interconnected under high temperatures. The material is characterized by good air permeability, easily recovers its shape after compression, and is able to warm at air temperatures down to -30 °C.

At textile enterprises, holofiber of various densities is produced. It is from this indicator that the thermal conductivity of the material depends:

  • If the density of the holofiber is not more than 80 g / m², then a jacket with such insulation is suitable only for autumn weather.
  • At air temperatures over -10° C, clothing with a filler density of 150g/m² is suitable.
  • To use the product in severe frosts, the density of the insulation should be 300g/m².

3. Sintepon

After the long-known synthetic winterizer transformed its device, outerwear manufacturers began to use this material as a heater with pleasure. A modern synthetic winterizer keeps its shape perfectly, retains heat well, and is inexpensive.

Coats and jackets on synthetic winterizer are recommended to be worn in late autumn or early winter when the air temperature does not drop below -10 ° C.


The Belgian company Libeltex, which has been producing insulation for clothing since 1945, has developed a new type of synthetic material, ISOSOFT

It consists of numerous balls of polyester fiber sealed between two layers of the thin polymer coating. Many air-filled cells make ISOSOFT the best insulation for adult and children’s clothing.

  • Thin ISOSOFT is suitable for sewing demi-season jackets and coats at temperatures below -5°C.
  • More dense varieties of the material can be used for the manufacture of winter clothing designed for frosts down to -30° C.

Is polyester hot or cool?

Polyester is a synthetic fabric that doesn’t let air circulate, as well as natural fibers, such as cotton or linen. This means that it can trap heat and moisture against your skin, making it feel hot and uncomfortable.

However, polyester can also be made with moisture-wicking properties, which can help to keep you cool by pulling sweat away from your body. Whether polyester is hot or cool depends on the fabric’s properties.

If you’re looking for a cool and breathable fabric, consider natural fibers or fabrics specifically designed for hot weather.

What season should you wear polyester?

Polyester is a synthetic fabric that is commonly used in clothing and other textiles. It is a versatile material that can be worn in different seasons depending on the style and thickness of the garment. Polyester is an excellent option for warm weather, as it is lightweight and breathable.

However, it can also be worn in cooler weather if the garment is thick enough or layered with other clothing. So, the season you should wear polyester depends on the specific garment and your personal preferences.

Is 100% polyester good for cold weather?

It depends on the specific polyester type and the temperature. Normally, polyester is warmer than natural fibers like wool, but it can still provide insulation in cold weather.

Some polyester fabrics are designed specifically for cold weather and have added features like a fleece lining or moisture-wicking technology to keep you warm and dry. However, if you are in extremely cold temperatures, it may be best to opt for a natural fiber or a synthetic insulation like PrimaLoft.

But, it’s important to consider the specific fabric and its intended use when determining whether it suits cold weather.


So, Different types of polyester filler are designed for different temperatures and weather conditions. When choosing clothes with synthetic insulation, you need to ask the seller about the production method of the warming layer, its density, and other properties.

It is important to find out which company made the product you like and whether you can trust this manufacturer.
