Is this jacket warm enough for real winter?

It has a cotton fill and a hood, which handles cold, dry days and layering. Cotton fill insulates less than down and loses warmth when wet, so it is not the pick for wet or extreme cold.

No. The shell is a synthetic blend and the listing makes no waterproof or windproof claim. It sheds light drizzle at best; wear a shell over it in steady rain.

How does the fit run?

It is cut as a relaxed fit with a regular length. That leaves room for a sweater underneath, but slim builds may find it roomy through the body.

What is the fill made of?

Cotton, with a polyester lining. That gives soft, breathable warmth but slower drying and less loft than synthetic or down fills.

How does it compare with a down jacket?

Down is warmer for its weight and packs smaller. This jacket is bulkier and heavier for the same warmth, but the relaxed cut and hood suit casual everyday wear.

What should I check before ordering?

Confirm the shell is water-resistant enough for your climate and that the relaxed fit matches how you layer. The hood is fixed, so check you want that coverage.
