Is this coat warm enough for winter?

No. It is medium-weight polyester with no lining, so it works as a fall or spring layer. For cold weather you would need a wool coat or a heavier insulated jacket underneath or instead.

How does the sizing run?

The listing states Asian sizes run 1 to 2 sizes smaller than US and European sizing. If you fall between two sizes, take the larger one, and check the size chart before ordering.

Polyester. It is not a wool or wool-blend coat despite sitting in that category, so expect a soft, synthetic hand feel and limited breathability.

Does it have pockets?

The product information lists only buttons as a feature and does not mention pockets. Assume no pockets unless a seller confirms otherwise.

Can I machine wash it?

No washing instructions are given. Polyester knits like this usually do best on a cold, gentle cycle or hand wash and flat drying, but confirm with the seller first.
