Is this jacket warm enough for winter?

No. It is a lightweight insulated layer for cool weather, not deep cold. In winter, wear it under a shell or a heavier coat.

Does it work in rain?

It is not a rain jacket. Light drizzle is fine, but sustained rain will soak the shell and flatten the insulation's warmth.

Yes. Its low bulk fits under a hardshell or parka, which is how most people get the most from it.

It compresses into a small bundle for a daypack or carry-on, though it does not include its own stuff sack.

Yes, for its weight. The insulated baffles trap more heat than a fleece of similar bulk, but a fleece breathes better on hard climbs.

Machine wash cold on a gentle cycle and tumble dry low with dryer balls to restore loft. Avoid fabric softener and high heat.
