Abstract: Apparatus and a method for converting a conventional crew cap into a tubular article of outerwear. The crew cap includes a flexible outer layer and a flexible inner layer that together forms a crown portion and an opened end. An opening is positioned on and defined by either the inner layer or outer layer. In a first use, the open end of the inner layer is adapted to be worn by a wearer such that the crown portion of the inner layer covers the wearer's crown. To convert the cap into tubular article of outerwear, the layer not containing the opening is completely pulled through the opening to form a tubular article of outerwear having a first and second open end. The tubular article is adaptable to be worn by the wearer as a headband or neck warmer.
