So I just bought my first Kifaru pack, a woodsman. And I am looking to add a larger pocket to the back side basically covering the zipper. I found a photo on here of someone running a Sherman pocket in that position. With it in clipping and falling vertically away from the pack. And I am wondering if there a way to add a large compression pocket or shape charge in that same location. Either unclipping down vertically or sideways like a book to allow access to the main bag zipper?
