Abstract: A convertible garment bag is fabricated with alternate carrying means to permit the bag to be transported by the luggage handle, a shoulder strap or a backpack harness, thereby enabling a traveler to include in a single bag both formal wear and casual wear for all occasions, and, allowing the traveler the option of carrying the bag as conventional travel luggage or as a mountaineering pack. The garment bag is constructed in the form of an elongated casing with a hook at one end to hand the casing and contained garments for temporary storage with minimal wrinkling of the contained garments. The casing has a perimeter closure device to enable the casing to fold into multiple segments that interfasten to form a unitary compact pack for convenient transport by one of the alternate carrying means.
