How to Choose the Right Carry-On Backpack
1. Check Airline Size Restrictions
Most major airlines allow carry-ons up to 22″ x 14″ x 9″ (56cm x 36cm x 23cm), but budget airlines can be stricter. All backpacks on this list fit standard requirements, but always check your specific airline before buying.
Pro tip: Backpacks under 40L generally fit everywhere, including budget airlines like Ryanair and EasyJet.
2. Consider Your Trip Length
- Weekend trips (2-3 days): 25-35L (Aer Travel Pack 3)
- Week-long trips (5-7 days): 35-40L (Osprey Farpoint 40)
- Extended travel (2+ weeks): 40-45L (Tortuga Setout, Peak Design)
Remember: With laundry access, you can travel indefinitely with just 40L.
3. Match the Bag to Your Travel Style
- Adventure travel: Prioritize durability and comfort (Osprey Farpoint 40)
- Business travel: Choose professional appearance (Aer Travel Pack 3)
- Tech-heavy travel: Get superior protection (Peak Design)
- Budget travel: Maximize value (Cabin Zero)
- Long-term travel: Focus on capacity (Tortuga Setout)
4. Key Features to Look For
Essential:
- Clamshell or front-panel opening (easier packing)
- Lockable zippers (security)
- Padded laptop compartment
- Comfortable shoulder straps
- Hip belt (removable or stowaway)
Nice to have:
- Multiple carrying options (backpack, duffle)
- Water-resistant materials
- External attachment points
- Quick-access pockets
- Compression straps
5. Don’t Overpack
Bigger isn’t always better. A 40L backpack that’s comfortably packed is better than a 45L bag stuffed to maximum capacity. Leave room for souvenirs and unexpected purchases.
Frequently Asked Questions
What size backpack is best for one-bag travel?
40L is the sweet spot for one-bag travel. It’s large enough for 5-7 days of clothing (or longer with laundry), yet small enough to meet carry-on restrictions on virtually all airlines, including budget carriers.
Can I really travel with just a backpack?
Absolutely! With smart packing techniques like rolling clothes, using packing cubes, and choosing versatile garments, you can comfortably travel for weeks with just a 40L backpack. The key is doing laundry every 5-7 days.
What’s the difference between 35L and 45L backpacks?
A 45L backpack holds about 30% more than a 35L. For perspective: 35L fits 3-5 days of clothes, 40L fits 5-7 days, and 45L fits 7-10 days. Choose based on your typical trip length and whether you’ll have laundry access.
Do I need a backpack with a laptop compartment?
If you travel with a laptop, a dedicated compartment is highly recommended. It protects your device from impacts and makes TSA security checks faster. Look for compartments with padding on all sides, not just the back.
Should I get a backpack with a hip belt?
Yes, especially if you’ll be walking with the backpack for extended periods. Hip belts transfer weight from your shoulders to your hips, dramatically improving comfort. Look for removable or stowaway options for versatility.
How much should I spend on a travel backpack?
Budget: $60-100 (Cabin Zero)
Mid-range: $150-200 (Osprey)
Premium: $250-300+ (Peak Design, Tortuga, Aer)
A quality backpack is an investment. If you travel frequently, spending $200-300 on a backpack that lasts 10+ years is worthwhile.
Can these backpacks be used as everyday bags?
Some yes, some no. The Aer Travel Pack 3 works great as a daily work bag. The Osprey Farpoint 40 is too large for everyday use. Consider how you’ll use the bag when not traveling.
Are these backpacks waterproof?
Most are water-resistant (light rain is fine) but not fully waterproof. For extended rain exposure, consider a rain cover or pack important items in dry bags.
