Highly reflective black-colored winter scarf is knitted with super warm black and silver reflective yarn. It is warm and stylish, and is not noticeably reflective or different than a typical scarf. However, when light shines on it, such as from a vehicle's headlights, the scarf 'jumps into action' and lights up the night! The scarf is comfortable, long and wide (appx 65"x11"), and is designed with your safety and warmth in mind.
