Is this jacket warm enough for winter?

It is down-filled, so it insulates well for its weight. Down holds heat effectively in dry cold, but it loses loft when wet, so it is not the jacket for heavy rain.

What size does it fit?

It is listed as fitting a medium. The 1990s cut is boxy, so it leaves room for a sweater or hoodie underneath.

It is a secondhand Gas puffer from the 1990s, listed in very good condition. Expect light signs of age rather than a factory-new jacket.

How should I wash a down puffer?

Use a down-specific detergent on a gentle cycle, then tumble dry low with dryer balls to break up clumps. Never dry clean down unless the care label says so.

How does it compare with a new puffer?

It offers genuine down warmth and vintage Gas styling that modern jackets do not copy. New puffers give you technical shells, warranties and packability instead.
