Should I pack a sleeping bag?

No. Hostels provide bedding and it's too hot for sleeping bags most of the year. Bring a silk liner if you're concerned about cleanliness.

How much cash should I carry?

Carry $200-300 USD in clean, new bills for visa fees and emergencies. ATMs are widespread in cities but can be scarce in rural areas.

Do I need hiking boots?

Only if you're doing serious trekking. Lightweight trail runners are better for most travelers—they dry faster and work for both cities and light hiking.

Should I pack formal clothes?

One nice outfit maximum. You can buy formal clothes cheaply if needed for temples or upscale restaurants. Most places are casual.

How to Pack for Backpacking Southeast Asia

Pack light with quick-dry clothing, a 40-50L backpack, and essentials for hot, humid weather plus sudden downpours. Bring minimal electronics, strong sunscreen, and leave space for souvenirs. Most toiletries and gear can be bought cheaply once you arrive.

Choose your backpack size. Get a 40-50L backpack maximum. Anything larger becomes unwieldy on crowded buses and trains. The Osprey Farpoint 40 or similar travel backpack works better than a traditional hiking pack for city travel.
Pack for hot and humid weather. Bring 4-5 quick-dry shirts, 2 pairs of shorts, 1 pair of lightweight pants, and 1 light jacket for air conditioning. Skip cotton—it never dries in the humidity. Merino wool or synthetic fabrics only.
Prepare for sudden rain. Pack a compact rain jacket and rain cover for your backpack. Cheap plastic ponchos sold locally work fine too. Waterproof phone case is essential—Southeast Asia has serious downpours.
Minimize electronics. Bring phone, charger, portable battery pack, and universal adapter. Skip the laptop unless you're working. Many hostels have computers, and phone cameras are good enough for travel photos.
Pack health essentials. Bring SPF 50+ sunscreen from home (expensive locally), insect repellent with DEET, basic first aid kit, and any prescription medications. Pack more malaria prevention than you think you need if going to rural areas.
Leave room for purchases. Pack your bag only 70% full initially. You'll buy clothes, souvenirs, and replacement gear as you travel. Shipping stuff home gets expensive—better to pack light from the start.
