What is a down jacket?
Down jackets are known as a staple winter outer layer.
They’re light, warm, and increasingly available in highly designed models—but many people are still unfamiliar with what’s inside and how they’re built.
Here, we’ll clearly explain the basics—“What exactly is down?”—and how it differs from other representative fills.
Down is a type of waterfowl feather
- Main characteristics
- ・Down is a fluffy, downy feather
・No central quill; soft, cloud-like structure
・Spherical clusters trap air
・Interlocking fibers hold a layer of air
It offers excellent warmth and is mainly sourced from goose and duck.
Why down is warm: its structure holds plenty of air
- Main characteristics
- ・Down is a downy feather without a stiff quill
・Its fluffy, spherical clusters trap air
・The intertwined fibers retain an insulating air layer
・Goose down is generally lighter and warmer
Down excels at thermal insulation—different from feather or synthetic fill in role
Down is characterized by high warmth retention, while feather and synthetic fills each have different roles. It’s important to understand the features and use them appropriately.
*Even if they look similar, their structures and performance differ clearly, and each material has strengths in different applications.
Features of feather
- Flat feathers with a central quill
- Less warm than down but more resilient and shape-retaining
- Often blended with down (e.g., 90% down + 10% feather)
Features of synthetic fill
- Primarily polyester and other man-made fibers
- Engineered to mimic down and retain warmth even when damp
- Generally heavier and less warm than down at the same loft
- Cost-effective and preferred by those avoiding animal-derived materials
