CargoVise uses four overlapping wings and an internal roll-up bag that stow, fold and compress like a burrito! See how it works here:How It Works
I love that I can use one bag for all my gear. Hunting trips are now easy and functional with my Cargovise in tow.
Finally, a compact bag for all my gear! Thank you! Now I don't have to worry about things breaking or getting lost in my trunk.
