10 Best Travel Carry On Backpacks 2025 in the United States

The Osprey Daylite Expandable 26+6 Travel Pack is a lightweight and durable choice for travelers seeking a versatile carry-on backpack. Weighing just 1.75 pounds, it is easy to carry without adding bulk, and its materials are designed to withstand frequent use. The pack starts with a 26-liter capacity but can expand by an additional 6 liters, providing extra space without worrying about airline size restrictions. Its size fits well as an international personal item, allowing it to be stored under the seat on most flights to avoid gate check hassles.

This backpack features one main compartment complemented by useful pockets, including two stretch water bottle holders and a front zip pocket for quick access to essentials. The padded AirScape back panel offers good ventilation and ergonomic support, helping keep your back comfortable during long travel days. While it has only a single main compartment, which might limit organization for those preferring many separate pockets, the included tech sleeve and luggage pass-through add convenience for travelers using rolling bags.

This backpack is well suited for travelers who prioritize lightweight comfort and flexible space within carry-on limits, especially for day trips or as an extra personal item on flights.

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 Topo Designs Global Travel Bag 30 Liter is a versatile carry-on backpack that suits travelers who want one bag for weekend or short trips. It’s carry-on compliant, so you can easily take it on US and many international flights without checking it in. The bag weighs about 3 pounds, which is on the moderate side—not too heavy but not ultra-light either. Its dimensions (around 21 x 15 x 7 inches) make it roomy enough to hold essentials for a few days without being bulky. Built from durable recycled nylon materials, including heavy-duty ballistic nylon, it’s designed to withstand wear and tear while being environmentally mindful.

Inside, it features multiple compartments: an external laptop sleeve, mesh pockets, zippered security pockets, and slip pockets that help keep your gear organized and easy to find. Comfort is addressed by offering three ways to carry—backpack straps, a shoulder strap, and grab handles—giving you flexibility depending on your travel style. However, the bag’s design leans more toward functional than cushioned comfort, so if you’re planning to carry it for long periods, it might feel a bit firm.

Some travelers might find the 30-liter capacity limiting for longer trips, but it’s great for packing light and staying organized. This bag is a solid pick for travelers who prioritize durability, organization, and carrying options in a carry-on sized backpack, though it may not be the best choice for those needing extra padding or larger capacity.
