This will narrow your decisions of what to wear and pack. Warmer, tropical climates allow for lighter articles of clothing, such as shorts and tank tops. Colder climates require heavier clothes that would keep you warm, such as jackets, sweaters and coats. Pack a small umbrella if the forecast calls for rain. If an unexpected deluge happens at a time that you absolutely must be outside, ask your host or front desk at the hotel if you can borrow a larger umbrella.

To create even layers, drape the top of the second article on top of the bottom of the first. Make use of spaces that remain. Look for smaller spaces between layers and between articles of clothing. Tuck socks, underwear, and chargers in these spaces. Make use of its additional space. In addition to your computer, use pockets for any necessary paper documents.
