This is a waterproof zipper bag that you carry everywhere and it has important papers, clothes, medical items. The term "go bag" means you can leave or go at any time. It must have all you need to leave the country without returning to your accommodation. Be careful carrying your "go bag" it’s bad if it gets stolen. Before you travel photocopy all important documents (credit cards, passport. visa papers, anything government issued. Leave these copies with your office/next of kin.
