I love this neck warmer. I love that it is a knit pattern on the outside with a warm fleecy liner on the inside and that it cuts the windchill when I bury my face into it. It also smells really nice, not sure if that is the Biotherm factor but doesn't matter to me. Even long after that wears away, I will love this piece of my winter kit. Note: It is a bit on the thick side of neckwear so it's hard to tuck into the neck of my winter coat, but that's not too big a deal for me, but it may be for others.
