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.

Goose down fill is the gold standard in thermal insulation, so down-filled jackets will definitely keep you warm.
