The Helmet Liner is flat-stitched micro fleece, cut close so it fits under a ski or snowboard helmet and stays flat where the straps sit. It covers the head, ears, and neck on lift mornings and cold walks to the hill. For a piece that works three ways as a gaiter, a hood, and a face mask, the Long Neck is the one to look at. For the coldest mornings when the wind is the problem, the Balaclava covers more of the face.
