Should I bring a rain cover?

Yes. Even if your pack is 'water resistant,' bus roofs and heavy tropical downpours will soak your gear. A dedicated rain cover doubles as a theft deterrent in crowded markets.

Is a rolling suitcase better?

No. South American cities frequently have steep hills, stairs, and unpaved, uneven sidewalks. A backpack is the only way to stay mobile.

What's the best way to secure my bag on night buses?

Always keep your daypack with valuables on your lap. For the main bag stored in the under-bus compartment, use a lock and a personal luggage tag, but assume the contents could be vulnerable—never pack your passport or electronics in the main bag.

Choosing the Right Backpack for South America

Prioritize a 45-55 liter pack with a robust, adjustable hip belt and a front-loading zipper. You need to be able to carry your life on your back for transit while keeping it light enough to avoid checked bag fees and stress on cobblestone streets.

Define your capacity. Stick to 45-55 liters. Anything larger encourages overpacking and will be forced into checked luggage, which increases the risk of airline loss. If you can't fit your gear into 50L, you are carrying too much.
Prioritize front-loading access. Avoid top-loading hiking packs. In hostels, you need to access your gear without dumping everything out. Look for a 'clamshell' or front-zipping design that opens like a suitcase.
Test the suspension system. South American travel involves long walks to terminals and uneven pavement. Ensure the pack has a proper internal frame and a weight-distributing hip belt. If the hip belt is thin webbing, skip it.
Check for security features. Lockable zippers are non-negotiable. Look for packs where the main zippers meet at a single point, allowing you to secure them with a single TSA-approved padlock.
