Do I need an internal frame?

Yes. For anything over 30 liters, an internal frame is essential to maintain the structural integrity of the bag and distribute weight to your hips.

Is a travel backpack better than a hiking backpack?

Travel backpacks are built for accessibility and security (lockable zippers, stowable straps for flights), while hiking backpacks are built for aerodynamics and hydration bladder access. For general travel, a travel-specific design is superior.

Choosing the Right Backpack for Long-Term Travel

Choose a 40-50 liter pack that fits your torso length perfectly, not just your height. Prioritize a pack with a sturdy hip belt to transfer weight off your shoulders and front-loading access instead of traditional top-loading.

Measure your torso. Use a soft tape measure to measure from the C7 vertebra (the bony bump at the base of your neck) to your iliac crest (the top of your hip bones). This measurement determines your pack size (Small, Medium, or Large), not your total body height.
Prioritize suspension over features. The most important part of a bag is the harness system. Ensure the hip belt is padded and centered on your iliac crest. If the bag doesn't have load-lifter straps at the shoulders, do not buy it.
Pick a front-loading design. For travel, avoid 'top-loaders' where you have to dump your entire bag to find a clean shirt. Look for a 'clamshell' or front-opening zipper system so you can access your belongings like a suitcase.
Limit your capacity to 45 liters. If you have a 60+ liter bag, you will fill it. Aim for 40-45 liters. This is the sweet spot for carry-on compatibility on most airlines and ensures you aren't carrying unnecessary weight for months on end.
