I’m all for a real backpacking backpack, but this North Face Duffel is a great alternative if you aren’t needing to hike with all your gear long distances. This bag is water proof and perfect for rainy climates. It even has straps for carrying it on your back.
I love a sheet sleeping bag liner. They are great for questionable hostel beds. You can sleep comfortably in the sheet and not worry about touching anything else. This Cocoon is 100% cotton, but I love 100% ones as well.
If you are traveling for a long period of time, you are going to need to do laundry. Laundry mats are not easy to find overseas, so I do a lot of sink washing. A solid laundry detergent won’t spill in your bag and you’ll have not trouble getting it on a plain.
And speaking of laundry, there is no better underwear to travel with then Ex Officio underwear (there are of course ones for woman as well). You can wash them at night and they will be dry by the morning.
I’m a redhead, so sunscreen is a MUST. I love solid version like this Neutrogena one. Again, the less liquids you pack the better, and this one is great for sensitive skin types.
A dry bag is awesome if you are going to be on boats or the rainforest at all. I carry a small one like this one from REI to put my camera and valuables in.
When you are living out of a backpack, organization is key. I love ditty bags and sorters like this mesh set from Ikea. It’s nice to not have to dig through your whole bag to find one specific thing.
If you are heading to the tropics, I hope that involves tropical reefs. We love snorkeling and diving, this waterproof digital camera is a fun travel camera. Not only can you take pictures underwater, but you don’t have to worry about dirt, sweat and dust.
