[header] How to pack a duffel bag [title] Pack only what you need. [step] Make a list, and check off items as you pack them so that you know exactly what you do and do not have. Separate your list into categories: e.g. clothing, electronics, food, toiletries, documents, and gear. 
Consider the weather, the duration of the trip, and the range of expected activities. Make sure that you will be prepared for every situation that you will reasonably encounter-but be careful not to over-pack.
