A headover is not exactly a new idea. It is a multifunctional garment that can be used as a hat, a scarf, a bandana etc. One of the problems when using the product in a cold climate is that you get a lot of ice on the inside when you breathe.   The neck gaiter is a 2 layered headover with WoolNet Original on the inside, and wool interlock on the outside.     You get a warmer product because of all the air trapped inside, and the garment also has a hole in which to breathe. This minimizes the ice problem a great deal.   One size. 55g.
