Cozy fashionable and effective heated scarf for those brisk winter months. Comes with a lightweight rechargeable 7.4V battery, charger and User Manual. I've been wearing this heated scarf under my jackets and over my sweaters for complete wind-blocking warmth. It's made of 3M Thinsulate, breathable and feels premium to the touch. The flexible heating coils are located in the rear of the scarf and evenly distributes heat in three different modes: Low, Medium and High. After charging the battery and connecting it, simply long-press the Ororo button, wrap the scarf around your neck and insert the other end of the scarf into the slit. It will stay in place and warm you up in a few seconds. Perfect attractive fit for both men and women. Ororo recommends handwashing only without the battery and of course, zip locking the battery compartment. A winter must have. Great for outdoors while working, camping, biking/running or having a stroll in the cold months. Recommended.
