London Fog Coventry Wool-Blend Overcoat vs Michael Kors Men's Classic-Fit Sport Coat

Buy the London Fog Coventry if you need one coat for cold commutes and weekend wear. It is a long, insulated wool-blend overcoat with a full lining and a relaxed cut, and owners call it warm, well-made and good value, though many say it runs large. The Michael Kors sport coat is a lighter tailored blazer in a wool, silk and cashmere blend with a two-button front and double vent; its 5-star rating rests on only 33 reviews, so treat it as promising rather than proven. Pick it for dressier indoor occasions, not for winter warmth.

• Choose the London Fog Coventry if you want a long, insulated overcoat that covers a suit or sweater and holds up to cold weather.
• Choose the Michael Kors sport coat if you want a sharp tailored layer for weddings, offices and dinners where a heavy coat would be too much.
