Why should you choose your down jacket based on the temperature?

The cold affects us differently depending on the intensity:

-5°C: crisp cold, but often bearable with thermal layers and a mid-season down jacket.
-10°C: need for maximum insulation, dense down or advanced technical materials.
-15°C and colder: long down jackets, premium filling, fur-lined hoods, and essential accessories.

The choice also depends on your activity: city life, mountains, brisk walking, or daily commuting.
