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 Osprey Sojourn 22"/45L Wheeled Travel Backpack offers a versatile option for travelers who need both a suitcase and a backpack. Its 45-liter capacity makes it spacious enough for extended trips, while the dimensions (25L x 15W x 9H inches) are generally within carry-on size limits for most airlines. One of its standout features is the deployable AirScape harness and hipbelt, which can be used when needed and tucked away when not, providing flexibility between wheeled and backpack carry options.

The high tenacity and ballistic recycled materials ensure durability, making it a sustainable choice. The oversized 90 mm wheels are designed to handle rough terrain, making it easier to maneuver in various conditions. However, at 7.7 pounds, it is relatively heavy for a carry-on backpack, which might be a drawback for those who prioritize lightweight luggage. Comfort is enhanced by the optional harness and hipbelt, but the weight could still be a concern for long periods of carrying.

With a customer rating of 4.3 out of 5 stars, it is well-received, but some users may find the weight and size a bit cumbersome. This backpack is ideal for travelers who need a durable, flexible, and spacious carry-on that can adapt to different travel conditions.
