After only a short time above the forest line, you will appreciate the warmth provided by this tunnel neck scarf. It effectively prevents the icy wind from penetrating under your clothes, and you can pull it up to protect your face. It's made from a soft, supple merino wool knit and has all the great properties of wool - it insulates even when wet, and it's moisture and odor resistant. The merino wool used in the base layers of the Bergtagen line is produced without shearing the sheepskin and is traceable back to the farm of origin.
