How to pack for a tropical backpacking trip

Limit yourself to a 40L backpack to stay mobile in heat and humidity. Focus on lightweight, moisture-wicking synthetic fabrics that dry overnight and leave 25% of your bag empty for souvenirs or necessities.

  1. Choose your luggage. Use a 40-liter maximum capacity backpack with a harness system. Anything larger will get too heavy for humid weather and won't fit in the overhead bins of smaller regional airlines.
  2. Select the right fabric. Avoid cotton entirely. It stays damp and heavy. Pack merino wool or synthetic materials that wick moisture and dry within 4 hours.
  3. Utilize packing cubes. Use three medium-sized compression cubes: one for tops, one for bottoms, and one for undergarments/socks. This keeps your clean clothes dry when the humidity hits 90%.
  4. Manage your liquids. Bring solid versions of soap, shampoo, and sunscreen. They won't leak in your bag and count as zero ounces toward your carry-on liquid limit.
How many changes of clothes do I actually need?
Pack for 7 days. Even if you are gone for a month, you will wash your clothes weekly at local laundry drop-off services.
Should I bring a towel?
Bring a microfiber travel towel. They are tiny, dry fast, and take up 1/4 of the space of a standard cotton towel.
