I was tired of the wife always stealing my Coal M.T.N. neckwarmer so I got her this. And that is probably the best purchase I've made. It's a game changer. Thin enough to tuck under the helmet, or goggles if want to pinch it over your nose. Breathable. She has worn this night boarding, powder conditions, and chilly blue bird days at 12k feet in Colorado. She still raves about it.
