This bag was designed specifically for giant Hangar 9 RV 4, to carry both wing panels in one bag. It has all our exclusive features including a full-length, custom zipper, pockets for a small hardware box and the wing tube. It also has our canvas/3/4"-thick padding/fleece fabric stack that does a great job at protecting wing panels. There is also a padded, flannel-wrapped divider to keep the panels separate.
