Yes they call it a sweater, but yes they say it is waterproof or resisitant. The product is well made and looked good on. Problem is that it is more like a liner then a winter jacket. It would be good in cool weather, but not cold. Sorry for those who said it was, they must have anti freeze for blood. I wore it when it was in the 40's with a sweatshirt and was not warm. Bit it was wll made and looked good. Wear it under a coat or in the early sring or fall.
