When it's cold, a scarf can really make a difference to your comfort and can stop cold air from getting into your jacket and cooling down your core. For outdoor sports, though, a long scarf can get in the way and end up being a hindrance. If you still want to protect your neck in cold and windy conditions, you should reach for the versatile tube scarves. These can be worn around the neck, pulled over the mouth and ears, and used as a headband. Tube scarves in sports are made of functional materials, are soft, very light, breathable, warm, are moisture-regulating, dry quickly and are available in a wide variety of colours and designs. There are also summer scarves made of a cooling material that protects against UV rays and keep insects away from your neck.
