The loose structure of down feathers traps air. As a result, energy cannot be transmitted easily through down feathers. This means birds are insulated from cold air outside, plus their body heat doesn’t escape easily either. Human beings discovered that down feathers are good for insulation long ago.

Is goose down the best insulator?
The warmest, lightest down comes at a premium price because it’s sourced from mature geese. This is the best insulator because the high-loft goose down has a very fine construction.
Why are down jackets good insulators?
Like a sponge that traps water, down traps air and allows it to heat up yet also breathe at the same time. Compared to artificial fibers, down is one of the best insulators of clothing, being lighter and trapping more heat than other materials.
Does goose down keep you warm?
Down jackets keep you warm the same way goose down keeps geese warm—which is also the same way the newer synthetic insulation materials keep you warm. By trapping pockets of warm air close to the skin, keeping the warm air in and the cold air out.
How does down trap heat?
Down clusters trap pockets of air, which in turn trap warmth from your body, giving you the comfort and insulation you need. What is Fill Power? In simple terms, Fill Power measures the loft of the down clusters. The more loft the clusters achieve, the more air is trapped and the more insulation is achieved.
What is the warmest synthetic insulation?
Synthetic Jacket Comparison Table
| Jacket | Price | Insulation |
|---|---|---|
| Cotopaxi Teca Cálido Hooded | $150 | Recycled polyester (60g) |
| Patagonia Micro Puff Hoody | $299 | PlumaFill (65g) |
| Arc’teryx Proton LT | $299 | Coreloft Compact (60g & 80g) |
| Patagonia Nano Puff | $199 | PrimaLoft Gold Eco (60g) |
Is goose down warmer than synthetic?
Down is lighter and weight-for-weight it’s warmer than synthetic insulation. But down fails to insulate when it’s wet. Synthetic insulation, on the other hand, maintains its insulating power in damp conditions.
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.
Why does down keep you warm?
Down feathers and other insulation keep you warm through trapping heat from your body in tiny air pockets within the insulation, so higher fill ratings mean more trapped air, which translates to more warmth per ounce of down.
Does down still insulate wet?
Down requires air to create a thermal barrier that retains warmth. Performance When Wet: Down provides zero insulation when wet. Having said that, treated Water Repellent Down absorbs 30% less water than untreated down, dries 60% faster and retains much of its loft even when exposed to moisture.
How long should a goose down duvet last?
five years
How long should a goose down duvet last? A good quality goose down duvet should definitely last the recommended five years. Particularly if you look after it well. Don’t over wash your duvet, just once every 6 to 12 months, and always protect it with a duvet cover, preferably cotton which is breathable.
What kind of down is the warmest?
Numbers don’t lie, the higher the fill power, the higher quality the down, and the more compressible it will be. A high fill power combined with a high fill weight is a recipe for maximum warmth. “
Why is down such an effective insulator?
The loose structure of down feathers traps air. As a result, energy cannot be transmitted easily through down feathers. This means birds are insulated from cold air outside, plus their body heat doesn’t escape easily either. Human beings discovered that down feathers are good for insulation long ago.
Is down or wool warmer?
Down coats often provide more warmth than wool coats, but you should always check the warmth rating of the coats you’re considering.
Are down jackets warmer than synthetic?
What is the difference between down and synthetic jackets? 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 synthetic down as warm as real down?
Although it works in the same way as down—body heat gets trapped by the fibers’ loft—synthetic insulation in general is less warm, heavier, and less compressible than down.
Which is warmer down or PrimaLoft?
PrimaLoft vs Down Insulation: Who’s the Winner? In most situations, down insulation will be your best bet. It’s warmer, lighter, more compactable, and will last longer than any synthetic insulation coat.
Can polyester fill be as warm as down?
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.
Is down warmer than Thinsulate?
Ounce for ounce, down is warmer than nearly all synthetic insulations. Very few manmade fibers can match down’s warmth-to-weight ratio. Down retains its shape and loft well. With proper care, it can last for decades.
What happens if down gets wet?
When down gets wet it clumps together and loses its loft, so it performs poorly at holding in heat. But when it’s properly washed and dried, down will fluff up just like new and insulate your body much better. In addition, washing a down coat is super easy.
Are down jackets too warm?
Down is known to be a really good insulator. It creates several small air pockets which trap warm air and retain heat, thus keeping you really warm. Down jackets are very comfortable in extreme cold temperatures.
