1. At the bottom of the vertical zipper, there is a piece of fabric you can hold to help rip open the top 2 zippers. 2. You can create a duffle bag opening if you keep the top 2 zippers closed and just open the vertical zipper.
Thanks for the feedback. We referenced Mystery Ranch's own video and they seem to have said 3-Zip. I guess as long as everyone faham what we're trying to say. haha
