Is this jacket warm enough for winter?

No, not on its own. It is a light down layer for cool weather; in freezing temperatures you would wear it under a shell or a heavier coat.

Can it really pack into its own pocket?

Yes, that is the point of the design. It compresses small enough for a daypack or carry-on, which makes it a good travel layer.

How does it compare with Uniqlo Ultra Light Down?

Both are thin packable down layers. Uniqlo publishes its fill power and has a longer track record; this one stands out mainly for its plus-size range.

No. The shell is not waterproof or windproof, so it is best used in dry, mild conditions or under an outer shell.

How should I size it?

It is cut to layer, so most shoppers take their usual size for a mid-layer and size up only if they want to wear a sweater underneath.

Use a gentle cycle with down detergent, tumble dry low with dryer balls, and avoid fabric softener so the down keeps its loft.
