10 Best Travel Carry On Backpacks 2025 in the United States

The MATEIN 45L Travel Backpack is a solid choice for travelers looking for a large, versatile carry-on bag. Its 20 x 13.4 x 8.6 inch size meets most airline carry-on requirements and offers expandable storage, which is great if you need extra packing space for weekend trips or business travel. Weighing just over 2 pounds, it’s lightweight enough to carry comfortably without adding much bulk. The backpack is made from water-resistant polyester, which helps protect your belongings from light rain or splashes, and the strong zippers add durability for frequent use.

This backpack shines in organization, with a large main compartment featuring compression straps to keep your items secure and multiple pockets for smaller essentials like your phone or earphones. The convertible design is a neat feature—hideaway straps let you switch from backpack to briefcase style, and a luggage strap lets you easily attach it to rolling suitcases, making airport navigation smoother. Comfort is taken care of with padded, adjustable shoulder straps, a ventilated back panel to reduce sweat, and a sternum strap to distribute weight evenly on your chest.

On the downside, while its size is generous, it might be a bit bulky for travelers who prefer minimalism or need to fit this under tighter airline seat spaces. The material, though water-resistant, isn’t fully waterproof, so heavy rain could still be a challenge. Also, the backpack’s style is somewhat plain, which might not appeal to those wanting a more fashionable look. This backpack is a practical and comfortable option ideal for weekend travelers, business commuters, or anyone who needs a durable, expandable carry-on. Its thoughtful features and solid construction make it a dependable travel companion, especially for those who value flexibility and organization.

The Thule Aion Travel Backpack is a solid choice for travelers looking for a functional and stylish carry-on option. With a capacity of 40 liters, it offers ample space for personal items, making it ideal for short trips or as an additional bag for your travels. One of its standout features is the use of 100% recycled polyester and a durable water-resistant coating, which not only supports eco-friendly practices but also helps keep your belongings protected from the elements. The removable TPU rolltop bag allows for additional organization, helping users keep items separate and easily accessible. This is particularly useful for travelers who want to streamline their packing.

On the comfort front, the backpack is designed with padded storage that can accommodate a 15.6-inch laptop and a 12.9-inch tablet, ensuring your tech gear is safe during transit. However, the optional Thule Aion Sling Bag, sold separately for use as a hipbelt, might not be necessary for everyone and can add to the overall cost if you choose to purchase it.

While the Thule Aion Backpack has many strengths, it’s essential to consider its weight of 1215 grams (approximately 2.68 lbs). This might feel a bit heavy for some users, especially when fully packed. Additionally, the size dimensions (6.3 x 13.78 x 21.65 inches) are relatively standard, but could be a tight fit in some airline overhead compartments, depending on the specific airline regulations.

The Osprey Fairview 36L Women's Wheeled Travel Backpack is designed as a versatile and convenient carry-on option, especially for those who want the flexibility of wheeling their luggage or carrying it on their back when needed. It meets the common carry-on size limits, measuring about 22 x 14 x 9 inches and holding 36 liters, which is enough space for a short trip or light packing. Weighing just over 5 pounds, it strikes a good balance between being sturdy and not too heavy to carry. Made from durable polyester, this backpack can handle rough travel conditions and should last a long time.

It features two main compartments, which is a bit limited if you prefer highly segmented packing, but it keeps things simple and straightforward. The backpack is comfortable to carry thanks to its padded shoulder straps, hipbelt, and a mesh backpanel that can be stowed away when you prefer to wheel it instead. Also, its design allows attaching extra smaller packs if you need more space.

The wheeled option is smooth and useful for airports or paved surfaces, while the backpack straps provide freedom on uneven terrain. One downside might be the limited compartments for organizing smaller items, which could be less convenient for travelers who like many pockets. This pack suits travelers looking for a durable, lightweight, and versatile carry-on that can adapt to different travel scenarios, particularly those who value comfort during longer walks or transfers.
