The Best Travel Backpack for International Travel in 2024

Ditch the hassle of checked baggage and cumbersome rolling suitcases. A carry-on backpack is your ideal travel companion, offering practicality, functionality, and freedom. Perfect for navigating airports, bustling city streets, or even venturing off the beaten path, the right travel backpack can hold a week’s worth of essentials, streamlining your international adventures. Whether you’re planning an extended backpacking trip across continents or a quick international weekend escape, a top-tier travel backpack will enhance your journey’s efficiency and enjoyment.

To find the best options, we rigorously evaluated 90 carry-on backpacks through seven comprehensive tests in our New York City lab. Our unique testing environment included a simulated airplane cabin, complete with actual seats and overhead bins. Following lab testing, we put each bag to the real-world test, using them on diverse trips for at least six months. Based on our extensive evaluations, these are our top recommendations for the best travel backpacks for international travel.

Photo: A vibrant Cotopaxi Allpa 42L Travel Pack in a well-lit studio, showcasing its robust design and carry-on size, ideal for international travel.

Pros:

  • Durable and water-resistant construction for diverse travel conditions.
  • Spacious 42-liter capacity, suitable for extended international trips.
  • Comfortable to carry even when fully loaded, enhancing travel experience.

Cons:

  • Larger size may only fit in overhead bins on smaller aircraft, requiring careful consideration for underseat storage.

Overview:

Cotopaxi, renowned for its commitment to sustainability and vibrant outdoor gear, consistently ranks among our favorite backpack brands. While we previously lauded the Allpa 35L Travel Pack as our top choice, the updated 42L Travel Pack has claimed the best overall spot as the ultimate carry-on backpack for international travel. This upgrade, launched in August 2024, features enhanced durability, improved weight distribution, and traveler-friendly additions like breathable air mesh shoulder straps, a convenient luggage pass-through strap, and an external stretch water bottle pocket.

During my personal testing of this backpack in the Travel + Leisure lab, I found the design significantly improved over the 35-liter model. The 42L offers more practical features tailored for the modern traveler. Although it’s a substantial backpack that might seem large or heavy for some, I found it remarkably manageable due to the supportive straps and updated hip belt. Navigating airports is also noticeably easier compared to wheeling a traditional suitcase. While additional internal organization would be beneficial, I easily packed enough clothing for a five-day international trip with room to spare.

The pack’s clamshell design features a large zippered mesh compartment on one side and two smaller zippered pockets on the other. A medium-sized zippered front pocket and a smaller top zippered pocket provide quick access to essentials like passports or phones. The padded rear laptop compartment includes a divider, accommodating multiple devices. While not designed for daily use due to its size, the Allpa 42L is exceptionally versatile for international flights, business trips, camping, road trips, and more.

The Details:

  • Capacity: 42 liters
  • Dimensions: 22 x 14 x 11 inches
  • Weight: 3.1 pounds
  • Material: TPU-coated 1000D polyester, 840D ballistic nylon paneling
  • Laptop Sleeve: 15-inch
  • Water-Resistance: Water-resistant

Best Anti-theft

Pacsafe Venturesafe EXP45 ECONYL

:max_bytes(150000):strip_icc()/pacsafe-exp45-anti-theft-carry-on-travel-pack-75449e6f2a3b497db73921d1032c780f.jpg)

Photo: Secure and feature-rich Pacsafe Venturesafe EXP45 ECONYL, highlighting its anti-theft technology for worry-free international travel.

Pros:

  • Advanced anti-theft features like locking zippers and wire-reinforced inner layer provide enhanced security for international travel.

Cons:

  • Some anti-theft features may be initially complex to use, requiring a learning curve for full utilization.

Overview:

The Pacsafe Venturesafe EXP45 ECONYL is our top pick for anti-theft carry-on backpacks for international travel, following recent anti-theft backpack testing. With a generous 45-liter capacity, it replaces a standard carry-on, offering RFID-blocking pocket, lockable zippers, and slashproof fabric for superior security. The clamshell compartment packs like a suitcase, accommodating our entire packing list with extra space. Numerous internal pockets enhance organization, but the safety features are paramount. Main zipper pulls lock together with a built-in padlock, deterring opportunistic theft.

Constructed from recycled polyester with a water-repellent coating, the exterior is durable. While a box cutter could slash outer layers, a wire-reinforced inner layer prevented penetration and damage to contents. Slashproof straps and an interior padded laptop sleeve further protect valuables. A stainless steel cable secures the backpack to fixed objects, though initial use can be slightly challenging. Comfortable to wear, albeit a bit bulky and heavy, this versatile backpack is packed with smart anti-theft features for peace of mind during international travel.

Other Carry-on Backpacks We Liked

While many carry-on backpacks met our quality standards, some fell short of our top recommendations due to minor weaknesses discovered during testing.

Earth Pak Summit Dry Bag Backpack: Durable, comfortable, and water-resistant 35-liter backpack with a waterproof phone case. However, the cumbersome roll-top closure makes packing less convenient for carry-on use, better suited for outdoor travel than international air travel.

Bellroy Transit Backpack Plus: Adjustable sternum and waist straps that tuck away, but pricier than better-performing alternatives.

Amazon Basics Carry-on Travel Backpack: Organized compartments and durable material, but lacks standout features.

Vancropak Carry-on Backpack, Extra Large 40L: Spacious and fits under airplane seats, but budget pick Asenlin performed slightly better at a lower cost.

Our Testing Process

We conducted over seven separate tests in our New York City lab to identify the best carry-on backpacks for international travel from trusted luggage and backpack brands. Our latest tests used a custom-built airplane set with real seats and overhead bins. To date, we’ve evaluated over 90 carry-on backpacks, assessing capacity, design, comfort, durability, and value. Following lab tests, T+L editors used backpacks on real-world travels for long-term insights.

Capacity tests involved packing three shirts, two pants, a jacket, shoes, and a toiletry bag, noting leftover space and compartment functionality. Design evaluation included assessing zippers, buckles, pocket functionality, and packability.

Comfort was rated by wearing backpacks for 10 minutes, noting weight distribution. Durability was tested by throwing bags from a height, checking for damage and content safety. Value was assessed unbiasedly, without price knowledge during lab testing. Real-world testing followed for up to six months to assess performance in actual international travel situations.

Tips for Buying a Carry-on Backpack

Consider under-the-seat versus carry-on bags

Check airline underseat dimensions if underseat storage is preferred. Verify carry-on size restrictions to avoid fees for overhead bin bags.

Keep in mind what the bag will be used for

Consider primary use: smaller, lightweight backpacks for walking-intensive travel; compression or organizational bags for air travel to maximize limited baggage space. Consider rolling options like rolling backpacks, weekenders, or duffel bags for added convenience when flying.

Frequently Asked Questions

How much can fit in a carry-on backpack?

Our tests packed three shirts, two pants, a jacket, shoes, and a toiletry bag with extra space. Ensure a laptop compartment and check laptop pocket size. Use compression packing cubes for more capacity.

Are all carry-on backpacks airline-approved?

Size restrictions vary by airline. Check product specs for dimensions. Verify underseat fit when packed.

Can I bring a backpack and an additional carry-on bag onto the plane?

Typically, one carry-on (overhead bin) and one personal item (under seat) are allowed, both within airline size limits.
