Is this jacket warm enough for winter?

It handles dry cold as a top layer or as a mid-layer under a heavier coat. The fleece lining adds real warmth, but it isn't windproof or waterproof, so it's not a substitute for a parka in wet or windy weather.

How does it compare with a regular denim jacket?

Same trucker shape and pockets, but the fleece lining makes it warmer, heavier and roomier. A plain denim jacket is lighter and more fitted but far less useful in cold weather.

Does it run true to size?

It tends to run roomy because of the lining. Check the chest and sleeve measurements and consider sizing down if you want a closer fit, or stay true to size if you plan to layer a sweater underneath.

Is the faux fur collar removable?

On most versions of this style the collar is attached, not detachable. If you want a cleaner look, check the product details before buying, since a fixed collar is a common complaint.

What can I wear under it?

A thin knit or tee works for milder days; a sweater fits if you size up. The lined body leaves less room in the sleeves, so very thick knits can feel tight.

How should I care for it?

Follow the care label. Denim with a fleece lining and faux fur usually needs a cold, gentle wash and air drying, and the fur collar is best brushed rather than tumble dried.
