Discovered today @ Home Depot. They're called gear ties. They are twist type ties, similar to what is on a loaf of bread. But they are of course heavier . They can be twisted or double wrapped. I played with the 'demo' laying there, and it seemed very strong. They come in 3" to 18" and in various colors. Could easily replace, take the place of Zip-Ties, and of course reusable .
