How and what to pack? Anyone who's Euro-Railed across Europe or trekked through South America has faced the questions. And there are really an infinite number of items that fall under "packing aid." But we've found a few key items really make a difference. First, packing cubes. Definitely stock up on a few of these. They let you pack so much more stuff in the same amount of space and keep everything organized. A good toiletries bag is also vital. Preferably one that you can hang in the shower or your room. We also recommend bringing carry on size containers. And finally, money belts and travel locks are a bit more on the security side of things, but keep what you pack secure. Everyone has their own packing theory. So choose a few key items and stay mobile, compact and organized.
