The SIXS multipurpose neck warmer protects your neck, nose and lips from the cold. At extreme temperatures, the neck warmer shields you from the cold but, at the same time, it lets out the excessive heat that would otherwise cause an uncomfortable damp feeling. It can also be used as a bandanna or as a balaclava. The seamless design gives this product top comfort and top performance. Good for sports training and competition during summer and winter.
