Synthetic insulation is mostly comprised of polyester and is created in short-staple fibers or long-staple fibers. Synthetic insulated jackets typically use short-staple fibers because they mimic down better, are more compressible, and keep you warmer initially.

What is synthetic insulation?
Synthetic insulation is designed to replicate the qualities of down, but retain them even when wet. It’s made with polyester fibers that are arranged in different sized filaments and intertwined, mimicking down’s lofty clusters. These ultrafine fibers trap warmth in air pockets, providing great warmth…
Is synthetic insulation good?
Synthetic fill does not lose its loft when wet, continues to insulate even when soaked, and dries out quickly. In addition, it’s more breathable than down and often cheaper.
What is a synthetic fill jacket?
Synthetic insulation is usually made from polyester, either raw or recycled. It’s engineered to mimic down’s lofty tendril structure trap warm air for insulation.
Are synthetic jackets as warm as down?
In addition synthetic insulation has a slightly higher weight-to-warmth ratio than down, meaning it needs to be heavier to achieve the same warmth as down. The upside to synthetic insulation is that it is much more resistant to moisture, and when it does get wet it dries faster.
What is the warmest jacket insulation?
Down Insulation
With a warmth-to-weight ratio three times that of synthetic insulation, down is pound-for-pound the best insulator in the world.
Which down jacket is warmest?
With the down weight and down to feather ratio being equal, an 800 fill power jacket will be warmer than a 500 fill power jacket. An 800 fill power jacket will require less down than a 500 fill power jacket to provide the same warmth.
Which is better puffer or padded jacket?
These jackets (along with your layers) can withstand temperatures up to -5 degrees. Having said that, if you compare the warmth to weight ratio, down jackets are the clear winner. If you have to attain the same warmth as a down jacket, the equivalent padded jacket tends to weigh a lot more.
What is the warmest synthetic insulation?
Synthetic Jacket Comparison Table

How warm is a polyester filled jacket?
Yes, polyester filling can be very warm and easily keep you warm at lower than 10°F, but it will weigh more than a down jacket. Many cold weather jackets are insulated by polyester, and some winter jackets feature multiple layers of polyester to make them extra warm.
How do I choose an insulated jacket?
The higher the fill power rating and the ‘loft’, the more warm air the down can trap, and the warmer and more packable the jacket. The maindrawback of down insulation is that it loses its ability to retain heat if it gets wet, because this causes the down to stick together.
Is goose down better than polyester?
You might have heard that down jackets are warmer than jackets with synthetic insulation. Down jackets do indeed offer a much better weight-to-warmth ratio – meaning that they offer more warmth for their weight than jackets with synthetic insulation.
Is down lighter than synthetic?
Synthetic insulation, which is made from polyester fibers, has a heavier warmth-to-weight ratio, which also affects a synthetic bag’s compressibility. This means that a synthetic piece with the same temperature rating as a down piece will be heavier and won’t pack down as small as a comparable down bag or quilt.
Which is better PrimaLoft or down?
The very fine fibers that make up this material keep you warm by trapping heat in the pockets of air that forms between them, similar to how down works. Even though PrimaLoft doesn’t have the same heat-keeping ability as down, it is the hands-down winner when it comes to water-resistance.
Are synthetic jackets waterproof?
Synthetic insulation doesn’t have the same issue – it doesn’t clump when it gets wet, so it can maintain the same performance level in different weather conditions. So, if you want a truly waterproof jacket, synthetic is the way to go.
What are North Face jackets filled with?
The North Face products are insulated with high-fill power goose down ranging from 500 to 800 fill, which represents the highest quality down commercially available.
What makes a jacket warm?
Down, synthetic materials, and wool are the most common types of insulation used in winter coats. Each has its own advantages, but the way they keep you warm is similar: Your body generates heat and warms the still air trapped between the fibers and filaments of the materials.
Is 80g synthetic insulation warm?
In general, 40g – 80g of insulation is considered thin loft insulation. It is on the thinner, lighter end of the insulation scale and is typically found in mid-layer pieces, or pieces that are intended to be layered. Both Arctica Heat 40 and Heat 80 are in this category.
What should I look for in a warm winter coat?
Special features
- A hood. Your head will lose heat quickly if it’s not covered properly, Lipman says, so prioritize a coat with a warm, insulated hood, even if it’s removable.
- Two-way zippers.
- Drawstrings at the hemlines.
- A color that suits your activities.
What does 700 fill goose down mean?
Down Fill Power
It is calculated by how much space 1 ounce of down clusters takes up in a cylindrical tube. For example, 1 ounce of 800-fill-power down will loft to 800 cubic inches, 1 ounce of 700-fill-power down will loft to 700 cubic inches, etc.
What temperature should I wear a down jacket?
You should wear your winter jacket if the temperature is above 30 degrees and your short walk takes more than 30 seconds. This theory is irrelevant if the temperature falls below 20 degrees. Even those who have survived frostbite are unable to go outside without protection.
