"A Traditional style swag" The new model Outback now has press studs and a zip. Each can be used independently or together for added security. The Outback model swag is manufactured in Western Australia using Australian water and rot proofed, 14oz poly cotton canvas and features press studs and a #10 chunky open ended zip down the full length of one side that are raised of the ground when set up, with a generous amount of canvas as a flood flap to stop water getting into your swag. Eyelets at each end allow it to be tied up from either or both ends. A generous extended top section at both ends prevents rain from getting into the ends of the swag. The Outback is open at both ends for airflow, and the press studs can be undone the full length, allowing the top of the swag to be thrown off to one side if required.
