I haven't been here in forever, but I make my own snuffer bags with relatively heavy nylon from sailrite. Problem is that it is in no way meant to stay out in the sun for a long time. If you leave the boat set up outside then it needs a cover. PM me if you want me to make you one, I am bored in the cold white north (you are colder) and could put it together for the cost of the materials.
lemme know
