Packing cubes make organizing your luggage a lot easier. They are simply a lightweight fabric cube (although most are actually rectangular) which hold your clothes nice and compact and also allow you to sort and separate different items.
Think of this situation:
You’ve arrived at your destination with your lightweight carry on bag. This bag is small, but you managed to fit all your clothes in by using your very efficient fold and roll method.  Everything fits just perfectly with no extra space.  But now unfortunately, you need to undo this hard work and try and find that tshirt which happens to be at the bottom of your bag. Now you need to rummage through your luggage, taking everything out.
The great thing about using packing cubes is, its so easy to unpack and repack clothes. When you arrive at your destination, its simply a matter of taking out the cube thats needed. No more rummaging through a bag! Packing cubes are essential for those flying, digital nomads, and one bag travellers.
