attractive energy and money-saver

I purchased this for my wife, who wears it almost daily. If you wear it in the house in winter, it allows you to turn the thermostat down, saving energy and money, while staying perfectly comfortable. Well-made, nice looking, light as a feather. Perfect for layering, too, as under a rain or wind jacket. This has for two months been her most-used article of clothing. Could easily pay for itself in the first month.
