Printed with a special ink that not only glows in the dark, it can also be directly drawn onto with a small penlight. The afterglow of the drawing remains on the sweat for up to five minutes and then gradually disappears, ready to be drawn on again. You can have endless fun creating illuminous shapes, lines and letters. A perfect sweatshirt for camping, festivals or parties. The graphic is cool for day or night. Everyone loves the interactive element of this t-shirt.
