The merino wool tube scarf is made of a single layer of thicker and stretchy fabric that protects against freezing from autumn to spring winds. The tube scarf is comfortable to wear because it can be easily pulled over the head and neck. Merino wool is 100% natural and the finest and softest wool that responds to body temperature. Keeps you warm, but at the same time does not make you sweat, because it conducts moisture away from the body. With a tube scarf, the neck is always covered and you don’t have to worry about the scarf moving.
