In choosing a down jacket, sometimes the warmth comparisons are easy. If two jackets are 800-fill-power, it’s very straightforward to check the fill weights and see how much warmer one is compared to the other (i.e. 5.6 oz. of 800-fill power will provide more warmth than 3.4 oz.).

How much insulation do I need jacket?
As a rule of thumb, 50g-100g of insulation is a good choice for spring or autumn, or as a technical mid-layer, whilst jackets with 100-200g of insulation are ideal for colder conditions.
What is a good insulator in a jacket?
Thermal insulation for jackets is typically made of two types of materials – down insulation, which is made from goose or duck plumage (the soft layer underneath the feathers); and synthetic insulation, or polyfill as its commonly referred are made of polyester fibers.
What is the warmest insulation for jackets?
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. Down used for insulation is derived from geese, ducks, or other waterfowl, and is a byproduct of the process of raising these animals for food.
How should an insulated jacket fit?
You should be able to lift an arm up above your head without the hem of the jacket lifting more than an inch or so, and the sleeves should be long enough that when carrying out the same motion, they aren’t mid-way up your forearm.
Do insulated jackets keep you warm?
Insulated shell jackets are a great addition to your COLD-WEATHER CLOTHING as they are designed to keep you warm in ways that noninsulated shells can’t. A typical insulated jacket is comprised of an outer layer—either a hard or soft shell—along with an insulating layer that’s constructed directly into the jacket.
How warm is 650 fill power down jacket?
A 650 down fill jacket with 330g of down may be as warm as an 800 down fill jacket with only 120g, but the 650 fill jacket will be bigger, heavier and take up more room when stuffed in your pack.
What does 40g insulation mean?
Thin Loft
Thin Loft. 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.
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.
What does 120g insulation mean?
Synthetic insulation is rated in gram weights — 60 grams (g) means a 1 meter by 1 meter piece of the insulation weighs that much. The heavier the weight, the warmer the insulation. Common synthetic fill weights range from 40 to 120 grams, and are often lighter in the sleeves than the body of a coat.

What does 550 mean on a North Face coat?
Thermal Insulation
The North Face® products are insulated with exclusive, high-fill power goose down ranging from 550 to 900 fill, which represents the highest quality down commercially available.
Are North Face jackets warm enough for winter?
How warm are The North Face jackets? Some The North Face jackets are warmer than others. It all depends on the kind of thermal insulation used in the jacket. The North Face uses traditional goose down fill for its warmest jackets to keep you warm.
Should jackets be a size larger?
Trying on Jackets in a Store. Opt for a jacket that’s 1 size larger than your shirt size. This is the general advice for buying a jacket so that it won’t be too tight. Having the jacket a little bigger than your normal size will also help to ensure that you can easily layer it over other items.
How do you know if a jacket is too big?
JACKET LENGTH
Raise your arms above your head and stretch your torso to see how long it is. A jacket that rides up past your waistband is probably too short — and can leave your midsection exposed to the cold. If raising up your hands causes the front of the jacket to billow out, it’s probably too big.
Should a jacket be loose or tight?
It should feel comfortable, but not so loose that there’s bunching of material. As with all winter coats, Alexander suggests trying it on with a jumper or whatever you’d normally wear underneath.
When should you wear an insulated jacket?

What is the warmest thinnest winter coat?
Consider the Kistler Aerogel Jacket. Its designers claim it’s the warmest and thinnest jacket on earth, in large part (okay, in practically all part) due to the fact that it incorporates a proprietary aerogel—aerogel being the lightest solid in the world, and the material NASA trusts to insulate its spacesuits.
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.
How do you determine the warmth of a down jacket?
One way to determine the quality of down is to look at its fill power. Ranging from about 450 to 900, fill power is the volume in cubic inches that one ounce of the down fills up; higher quality down lofts to a higher volume, so a higher spec number indicates warmer down.
Is 800 fill down warmer than 600?
The more insulating air pockets down traps, the warmer it will keep you! So in simple terms, the higher the fill power of a down jacket or sleeping bag, the warmer it will be for its weight. The image below illustrates the difference in volume between a gram of 600, a gram of 700, and a gram of 800 fill power down.
