This is a beautiful and distinctive jacket, well built, light in weight, rain-resistant,and comfortable to wear; but it lacks a lining of warm material. As stated in its description, it has a fancy "satin lining" with no insulation. However, it has room to allow a warm flannel shirt or a thin sweater underneath, because it is a full-cut jacket. I bought a medium size and have a 44 inch chest with 33 inch arm length. If one is tall or has long arms, better go with a larger size.

I recommend it alone for lightly cold/wet weather and for show (It attracts attention, lady attention!), but certainly not for functionality in very cold weather.
