windbreaker

This term describes a specific category of outerwear that prioritizes utility and protection over heavy insulation. It evokes an image of athletic or outdoor activity, typically associated with transitional weather where a full coat would be too heavy but a shirt alone would be insufficient.

In a fashion context, the word carries a casual, sporty connotation. It is distinct from a raincoat in that its primary purpose is to block wind, though many modern versions are water-resistant.
