Whether you are planning to be gone for a few months or a few years, packing for an around-the-world trip can seem like an impossible task. You have to assume you will experience the extremes of weather and climate, and that you won't always have access to a laundromat or, particularly, a dryer. You'll encounter cultural and religious sites that have a more conservative dress code. And, if you're like most long-term world travelers, you'll be staying in budget accommodations and couchsurfing, which necessitates a few additional items.

I have read many articles in travel magazines and even on some blogger's websites that focus on stylish travel attire, with photos depicting fitted jeans, silky tops, cute purses and jewelry, and fashionable shoes. While that may be fine to pack for a week-long city break, I wouldn't bring a single one of these items on an around-the-world trip. Why? Because in the end, comfort, function and durability matter far more than scoring style points for the traveler slogging through the rain with their 30 lb pack. In general I carry loose-fitting, stain-resistant, machine-washable, quick-dry fabrics in neutral colors that can easily be layered for cooler weather. Only things that really serve a purpose make the cut, as well as items that cannot be easily purchased in some places overseas.

After more than 20 years of extensive travel, including visiting all 50 states and more than 70 countries, this is now my go-to packing list for trips of two months or longer. It is originally based on my around-the-world trip from August 2010 to May 2011 which encompassed 278 days in 22 countries on four continents. Of course, the list gets modified if I expect the weather to be pretty consistent throughout the trip and/or if I plan to do a certain activity that requires specific gear e.g. camping. Still, the goal is always to carry as little as possible.

A good test is to do a trial packing session at least one month before you plan to leave. Then carry your bag around during your regular day-to-day activities and be sure it fits properly (or rolls easily if you decide to go that route) and isn't too heavy. Ideally you should also wear the clothes you've packed, essentially living out of your bag for at least one, but preferably two weeks while you're still at home. You really are going to be wearing the same clothes over and over again so be sure you're happy with the fit and color options. I also recommend washing your clothes all together in one machine, then hanging them to dry on your portable clothes line. This is the most likely scenario during your travels and you want to be sure they dry quickly and don't wrinkle horribly. Finally, if your main pack weighs over 30 lbs then I suggest you start paring down. Do you really need that extra pair of [fill in the blank]?

This list leaves minimal to no room for anything extra. That means you cannot buy souvenirs unless you are willing to pay to ship them home immediately or unless it is something that is consumable, doesn't take up space (like jewelry or postage stamps), or can be worn 24/7 (like a tattoo!). Besides, the best souvenirs are your experiences, your photos, and your lifelong memories.

In the list below, I have included the exact items that I own in most cases. These are all well-tested by yours truly; my toiletry kit is more than 20 years old! Also note that no company or manufacturer paid me to feature their products in this list. I selected and purchased every item myself, after trying almost every brand that makes a comparable product. Ultimately the list contains the items that fit me the best, were available at a low to moderate price, and that have held up over years of extensive use. For that reason, some of the exact styles are no longer available; you can find similar items by searching on each company's website or by entering key words on Amazon.

Do your research in advance and consult with your physician to get a sufficient quantity of any special medications and necessary vaccines a few months prior to your departure. Always carry a copy of your vision and medical prescriptions; I take a photo of mine and upload them to Google Drive for access anywhere. Don't forget that if you plan to carry your bags in the cabin on flights, the maximum size for liquids, gels and pastes is 3.4 oz or 100 ml and they must all fit in a quart-sized bag.
