A lightweight jacket designed specifically to function as a coat bridges casual and coverage in ways that feel contemporary. The distinction is that these are proportioned and structured to work as coats rather than just being oversized jackets. The weight is moderate enough for mild seasons and also to layer under heavier coats if needed. These come in materials like quilted cotton, technical blends, and structured knits. The casual silhouette and relaxed cut make them feel approachable. These lightweight functional coats work over almost everything. These are the jackets that technically function as coats because they have the length and structure to do the job without the weight of traditional winter coats.
