Should I get a backpack with wheels?

No. Wheels add significant weight and take up internal space. They are useless on cobblestone streets, gravel, or stairs—all of which you will encounter during solo travel.

Do I need a rain cover?

Yes, unless your bag is explicitly sold as 'waterproof' with sealed seams. Rain covers also double as a security deterrent in crowded areas by making it harder for someone to unzip your pockets.

Is a daypack necessary?

Yes. Bring a collapsible 15-20 liter daypack that fits inside your main bag. Use your main bag to move between cities and your daypack for daily exploring.

Choosing the Right Backpack for Solo Travel

Prioritize a pack between 35 and 45 liters that opens like a suitcase rather than a top-loader. If you cannot carry it comfortably for 20 minutes without setting it down, it is too big or too heavy for solo travel.

Determine your true capacity. Stick to 35-45 liters. Anything larger becomes a checked bag, which slows you down at airports and makes you a target for theft on public transit. If your gear doesn't fit in 45 liters, you are overpacking.
Select a clamshell opening. Avoid top-loading hiking packs. You need a 'clamshell' or 'panel-loading' design where the main compartment zips open fully, like a suitcase. This prevents you from dumping your entire contents on the floor every time you need one shirt.
Test the suspension system. The hip belt is more important than the shoulder straps. Load the bag with 15 lbs of weight at home and walk around for 15 minutes. 80% of the weight should rest on your hips, not your shoulders.
Verify carry-on dimensions. Check the maximum carry-on dimensions for the budget airlines you plan to use (usually 55cm x 40cm x 20cm). If your bag is larger, you will be forced to check it, losing your independence and mobility.
