waddy Report post Posted November 2, 2018 Has anyone had any experience using the heavy duty (even heavier than #10 sippers)? I have seen some that look like they might work really well as they are very tough and work as smooth as any zipper I have ever seen. I have seen them on a few products, but so far I haven't been able to find a source and I wonder if they would hold up in the long run. I'm talking about honest to gosh WORK chaps, not play toys!
