Is this jacket warm enough for real winter?

Yes. It is a heavyweight down puffer with a high fill power, so it handles freezing urban temperatures well. The cropped cut means you should pair it with a longer layer in wind.

It has a relaxed, boxy fit and runs large. Most buyers take their usual size for layering, or size down for a closer fit.

No. The nylon satin shell resists light drizzle but is not waterproof, and seams are not sealed. It is a cold-weather jacket, not a rain jacket.

Can I machine wash it?

Moncler advises dry cleaning for most down styles. Machine washing can clump the down and damage the satin finish.

How does it compare with a Canada Goose puffer?

It is lighter, shorter and more fashion-forward, with less weather protection and fewer pockets. Canada Goose jackets are built for harsher conditions; this one is built for the city.
