Don't freeze your face.
This balaclava is a very nice piece. Being merino it keeps warm even when wet from breathing. In fact, that is my favorite part. Every other face mask I have ever worn get cold and frozen after a short time of wearing it. This piece stays warm no matter how long I am out in the elements. The merino is also stink proof. You won't find yourself gagging after an hour or two of use because the smell is overpowering. I recommend this piece for cold weather activities.
