A simple Google search of "packing list + world travel" will show you how varied everyone's preferences are when globetrotting. I want things to be as simple as possible. I don't need fancy packing cubes; I opt for the gallon ziplock bags. When looking at clothing, I want a base wardrobe that is nimble enough to be used in multiple climates. Also, I'm known to be a penny pincher. I don't want to be throwing away stuff just to buy it again elsewhere.
So, with those things in mind, my packing scheme isn't the lightest and it isn't the most technical. It just gets the job done, which is seeing this amazing world of ours and not worrying about tearing my $500 puffy jacket on the last trek.

Recommendation
Be strategic in your storage system. I use four ziploc and vacuum storage bags to store all of my clothes and gear. With a backpack, you are consistently pulling everything out, so it's easier to have fewer storage compartments than a lot of little ones as you unload your backpack to find something.
