Is this cardigan actually wool?

No. The fabric is 100% polyester, so treat it as a synthetic knit rather than a wool garment. It is soft and light but not insulating.

It has a regular length and regular sleeves with a relaxed, straight cut. Sizes run from S to 3XL; if you want a looser layer, consider sizing up.

Can I wear it in winter?

Only as a light layer indoors or under a coat. Polyester knit adds little warmth on its own, so it is better for spring, fall or air-conditioned rooms.

How should I care for it?

Machine wash cold on a gentle cycle and lay flat to dry to limit pilling and stretching. Skip high heat, which can damage synthetic fibers.

Does it have pockets or a closure?

The listing shows a plain striped cardigan with no chest padding and no stated pockets. Expect a simple open-front or button-front layer depending on the style shipped.
