Should I get a bag with wheels?

Generally, no. Wheels add significant weight and take up space inside the bag. Unless you have specific physical limitations, a soft-sided backpack is superior for navigating cobblestones, stairs, and crowded transit.

Is a daypack necessary?

Yes. Bring a packable 15-20 liter daypack inside your main bag. Use the main bag to move between cities and the daypack for your daily activities.

Choosing the right backpack for long-term travel

Prioritize a pack between 40 and 50 liters with a robust internal frame and a weight under 3 pounds empty. Focus on fit and accessibility over features like extra pockets or built-in rain covers, which are easily added separately.

Determine your torso length. Measure from the C7 vertebrae (the bony bump at the base of your neck) to your iliac crest (the top of your hip bones). Match this measurement to the manufacturer's size chart; buying the wrong torso size guarantees back pain.
Select the right volume. Aim for 40-45 liters. This fits international carry-on requirements (typically 22" x 14" x 9") and prevents you from overpacking. Anything over 50 liters becomes a burden on budget airline weigh-ins.
Prioritize suspension systems. Look for a pack with a padded hip belt that transfers 80% of the weight to your hips rather than your shoulders. If the hip belt is flimsy, do not buy the bag.
Test with actual weight. Load the bag with at least 15 pounds of weight and walk around the store for 20 minutes. If the bag pulls away from your back or the straps dig into your collarbone, return it to the shelf.
Evaluate entry style. Choose a front-loading or 'clamshell' opening rather than a traditional top-loading hiking bag. This allows you to access your clothes at the bottom without dumping out the entire contents.
