10 Best Carry On Backpacks 2025 in the United States

The NOMATIC Navigator Rs 15L is a versatile carry-on backpack that easily adapts from 15 to 21 liters, offering extra space when needed without being bulky. It weighs about 2.7 pounds, which is on the heavier side for a backpack this size, likely reflecting its sturdy build and many compartments. Its design is sleek and modern, suitable for both business and travel use. The backpack’s size and structure suggest it’s made for everyday wear but might feel a bit firm when fully packed.

Organizational features are a strong point, including specialized pockets like an RFID-lockable security pocket, mesh zippered sections, and a fleece-lined laptop compartment that fits up to a 16-inch device, helping keep belongings safe and well organized. Durability seems solid given the brand's reputation and the higher weight, implying quality materials and construction.

This backpack is ideal for travelers and professionals who want a stylish yet practical carry-on that can store tech gear and personal items securely. It may not suit those who prioritize a very lightweight pack or require more than 21 liters of capacity. For anyone seeking a functional, well-organized, and adaptable backpack that carries essentials comfortably on the go, the NOMATIC Navigator Rs 15L is a strong contender.

The MATEIN Mens Backpack is a strong choice for travelers looking for a versatile carry-on bag. Its expandable design offers generous packing space, meeting airline size limits while letting you fit extra items when needed. Weighing just 13.7 ounces, it’s very lightweight, easing the burden when moving through airports or on day trips. Comfort is well addressed with padded, adjustable shoulder straps, a ventilated back panel, and a sternum strap to help distribute weight more evenly, which is great for longer wear. The backpack converts neatly between a traditional carry-on style and a briefcase look by hiding the shoulder straps, adding flexibility for different travel situations. Organizationally, it includes a front pocket for small essentials like phones and earphones, a large main compartment with compression straps to keep items secure, and multiple grab handles for easy handling.

Durability is impressive due to its water-resistant polyester fabric, sturdy zippers, and solid stitching, which should hold up well under various travel conditions. A luggage strap also lets you attach it securely to a suitcase handle, simplifying transit. On the downside, while the backpack is large, its expandable feature might add extra bulk that could be tricky in very tight overhead bins. Also, it’s designed as a unisex bag but the styling and color options may not suit everyone’s taste. This backpack is well suited for frequent travelers, weekend adventurers, or anyone wanting a practical, lightweight carry-on with smart features and good durability.

The TUMI Alpha Bravo International 2 Wheeled Duffel Backpack Carry-On is a versatile travel bag designed for convenience. Its standout feature is the combination of a backpack and duffel bag with wheels, making it adaptable to various travel situations. The size, at 21.8 x 14.0 x 9.0 inches, provides a substantial 40-liter capacity, ideal for short to medium-length trips. It's crafted from durable, weather-resistant ballistic nylon, ensuring that it can withstand the rigors of frequent travel while keeping your belongings secure.

Organizational features include interior tie-down straps and two zipper pockets, enhancing its practicality by keeping items organized and easily accessible. The weight, at 7.1 pounds, might be on the heavier side for a carry-on backpack, which could be a drawback for those prioritizing lightweight gear. Comfort-wise, its multiple carrying options—including wheels and backpack straps—offer flexibility, though it may not be as comfortable as dedicated backpacks when carried for extended periods.

Additionally, handy travel-smart features like a TSA-friendly lock and the TUMI Tracer add extra layers of convenience and security. This backpack is particularly suitable for travelers who value durability and versatility, but the weight and potentially higher price point could be deterrents for others.
