10 Best Travel Carry On Backpacks 2025 in the United States

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 coowoz Travel Backpack is a versatile and practical option for short trips or daily use, especially for travelers who want a lightweight, comfortable carry-on backpack. It’s made from waterproof polyester, which helps protect your belongings from rain and makes the bag durable over time. The padded shoulder straps improve comfort during longer wear, and the material also allows good air flow to keep you cool. At about 2.2 pounds, it’s light enough to carry around without feeling heavy.

The backpack offers multiple compartments including a wet bag for separating damp items and a separate shoe compartment, which is very handy for travel and sports activities. It also has two laptop sections that fit a tablet and a 15.6-inch laptop, making it suitable for work or study on the go. The size is designed to hold about 1-2 days worth of clothes and essentials, with dimensions around 17 x 31 x 42 inches, though the exact capacity is noted between 17 and 25 liters. This size works well for short getaways but might be tight for longer trips.

Some users might find the bag’s design more casual than sleek, which suits outdoorsy or everyday use better than formal business travel. The backpack excels in versatility, comfort, and protective features but may have minor inconsistencies in size details and is best suited for travelers needing a compact, organized bag for short trips or daily activities.

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.
