In the Antipodes, swag used to mean travel with one's personal belongings in a bundle. Nowadays, the word swag has moved on to mean a canvas bed roll that one would use for sleeping in while travelling lightly (walking, motorcycle, horse, camping in 4WD, etc.). I've got a fancy swag that's fully enclosed, with a hoop pole at the head end, and a mesh panel to let the fresh air in but keep the mozzies out.
