Pack in Plastic

consider packing all your luggage in transparent nylon bags, preferably zip lock, divided by item kind (underwear, shorts, t-shirts etc.) before you pack your backpack or suitcase. One plastic bag for each type of clothing. All this is extremely useful in quite a few ways: for instance, when unpacking your backpack just remove from the backpack a few nylon bags in order to immediately see piece of clothing you want. This way any overnight stay simply means taking a single clothing item that out of a nylon bag and not rummaging. This makes customs inspections a great deal of more pleasant.
