Is the DB Coat warm enough for real winter?

It is a wool-style overcoat, so it handles cool to cold city days when worn over a sweater or suit. For freezing temperatures or long time outdoors, a down or insulated coat is warmer.

Can I wear it over a suit jacket?

Yes. The cut is described as accommodating comfortable layering, so a suit jacket or a mid-weight sweater fits underneath. Very thick knits may feel tight at the chest because of the double-breasted overlap.

No. It is a tailored wool-style coat, not a raincoat. Light snow and drizzle are fine, but it is not built for heavy rain.

What is a double-breasted coat good for?

The overlapping front gives a more formal, structured look than a single-breasted coat. It suits business wear and dressier occasions and adds warmth across the chest.

How should I care for it?

Wool-style coats are usually brushed clean and spot-treated, then dry cleaned at the end of the season. Store it on a wide hanger so the shoulders keep their shape.
