Do I really need a mosquito net?

No. Almost all hostels and guesthouses provide them if you are in a rural or malaria-prone area. Don't waste the space.

Should I bring a money belt?

They are often uncomfortable in the humidity. A neck pouch under your shirt or a hidden zippered pocket in your pants is more effective and less conspicuous.

Is it better to buy gear there?

Buy your backpack and shoes at home where you can test them. You can buy toiletries, cheap t-shirts, and sunscreen anywhere in Southeast Asia.

Essential Gear for Backpacking Southeast Asia

Focus on a 40L to 45L carry-on compatible backpack and lightweight, moisture-wicking clothing. You only need one week’s worth of laundry, as inexpensive wash-and-fold services are available on every corner.

Select the right bag. Choose a 40L backpack with a clamshell opening rather than a top-loader. This allows you to see everything you packed without dumping it out.
Adopt the packing cube system. Use three packing cubes: one for tops, one for bottoms, and one for underwear/socks. This keeps your bag organized and prevents the 'everything-everywhere' mess during transit.
Prioritize quick-dry materials. Avoid heavy denim or cotton. Choose linen or synthetic performance fabrics that dry overnight, as high humidity makes air-drying cotton impossible.
Simplify your footwear. Bring one pair of comfortable walking sandals (like Tevas or Chacos) and one pair of lightweight sneakers. You will be taking your shoes off constantly to enter temples and homes, so avoid complicated laces.
Pack for monsoon and AC. Bring one lightweight, packable rain shell and one thin long-sleeve layer. Buses and trains in the region are often kept at freezing temperatures despite the heat outside.
