How much should my packed backpack weigh?

Keep it under 15kg (33lbs) when fully packed. Aim for 10-12kg if possible. Your back will thank you after the first week of carrying it.

Should I pack a sleeping bag?

Only if camping or doing multi-day treks. Most hostels provide bedding. A silk sleep sheet (200g) is lighter and more versatile for cleanliness.

How often will I do laundry?

Every 5-7 days in most places. Laundromats cost $3-8 per load. Hand washing in hostels saves money but takes time.

What about altitude sickness gear?

If visiting places above 3,000m (Cusco, La Paz, Quito), pack Diamox pills and extra warm layers. Altitude hits everyone differently.

Pack a Backpack for 3 Months in Latin America

Pack for variable climates with 2-3 weeks of clothes, focusing on quick-dry fabrics and layers. Keep your pack under 15kg and prioritize versatile items that work from beach towns to mountain cities.

Choose the right backpack. Get a 45-55L backpack with front panel access. Osprey Farpoint 55 or Gregory Compass 55 are reliable choices. Test the fit with weight before buying.
Pack for three climate zones. Bring lightweight clothes for hot coasts (30°C+), layers for temperate cities (15-25°C), and warm gear for mountains/Patagonia (0-15°C). Pack 2 pairs shorts, 3 t-shirts, 2 long pants, 1 warm jacket, 1 rain jacket.
Choose quick-dry fabrics only. Synthetic or merino wool. Avoid cotton except for 1-2 comfort items. Everything should dry within 24 hours. Uniqlo Heattech and Patagonia Capilene work well.
Pack 2 weeks of underwear and socks. 8-10 pairs each. ExOfficio underwear and Darn Tough socks last longest. This lets you do laundry weekly without stress.
Include practical footwear. Trail runners for walking, flip-flops for hostels/beaches, and hiking boots only if doing serious trekking. Allbirds Tree Runners or Merrell trail shoes work for most situations.
Pack tech essentials. Universal power adapter, portable charger (20,000mAh), waterproof phone case, backup USB cables, and offline maps downloaded. Anker makes reliable chargers.
Include health and safety items. First aid kit, water purification tablets, sunscreen SPF 50+, insect repellent with DEET, prescription medications for 4 months, and copies of important documents.
