So I would just slip this into my other tips of packing, but once you see these photos, you will understand.
Space Bags are the bomb. Why? Because you pretty much DOUBLE your clothing space for packing. (And trust me, I didn’t believe the cheesy infomercials either.) Kyle and I got a car top carrier that literally went from being full from a few winter coats and blankets, to transporting the majority of condensable clothing.
TIP: We did originally try backing them into out suitcases, but found it much more advantageous to save those for the nice clothing. With the majority of our clothes over top, much of the trunk space opened up.
