Our proven market leading design has been improved. Now featuring a full opening top with two heavy duty #10 spiral zips both running the full length of the swag and across the top (one on the net and one on the canvas) with two double pull sliders per zip allowing for entry from either side or full removal of top down to the foot panel. The Tracker is manufactured in Western Australia using Australian water and rot proofed, 14oz poly cotton canvas and features a large sand fly proof mesh "stargazer" section at the head and a full sand fly proof mesh top section with canvas cover. This feature allows the swag to be used on hot humid nights when the mosquito's or sand fly's are bad. The Tracker also features a sand fly proof net in the head and foot end of the swag with a zipped canvas panel that can be undone to expose the netting for airflow or zipped up to enclose the heat in cold wet weather. The canvas section at the head end also has an organizer pocket sewn in for easy storage of necessities. Both the head and foot end of the swag have an extended flood flap to stop water coming in should you choose to leave the netting exposed to allow some airflow when it's raining. Plastic coated Fibre glass poles with unique zippered retainer are provided along with guy ropes and sand pegs for set up as pictured above and are stored in a convenient zippered bag attached to the base of the swag at the head end. This bag is the first thing you see when you start to roll your swag and prompts you not to forget to put the poles back in when packing away your swag. All zips are heavy duty #10 spiral zip so it won't pull apart as happens with smaller weaker zips when set up with the tension required to sit properly.
