Remember to double check all of the clothing and make sure you have enough to cover your entire trip. For this example, all of the articles mentioned will fit into a bag that is slightly larger than a basic backpack. Regulations allow for a larger carry-on than this, so find a suitable bag.
When searching for a proper carry-on bag, remember to keep aspects such as a computer compartment in mind when searching for proper carry-on luggage. Separate, zipped, compartments can also be useful. However, be sure to place valuable items inside the main area in order to keep them safe. Consider keeping cash and important documents on your person, including all travel documentation (tickets, passport, other forms of identification, etc.)
