10 Best 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. With its expandable design, it comfortably meets airline carry-on size rules while offering extra space when you need it. Weighing just over 2 pounds, it’s lightweight enough to carry without feeling too bulky. Comfort is addressed through adjustable shoulder straps, a ventilated back panel, and a sternum strap that helps spread the weight evenly across your chest.

The backpack’s convertible style, allowing you to hide the shoulder straps and carry it like a briefcase, adds flexibility for different travel situations. Organization-wise, it includes compartments for essentials like phones and headphones, plus internal compression straps to keep your items secure and neat. It also features four external compression straps that help stabilize the load and protect the zippers. Durability is a strong point thanks to water-resistant polyester, sturdy zippers, and solid stitching, ensuring it can handle various travel conditions.

The relatively large size might be a bit much if you prefer a more compact backpack. Also, while it has many useful features for travelers, those seeking specialized compartments for tech gear or hiking might find it basic. This backpack is well suited for weekend and business travelers who want a reliable, roomy, and comfortable carry-on option with good durability and organization.

The Peak Design Travel Backpack 45L is a versatile option for travelers needing a carry-on backpack that adjusts to different trip lengths. Its expandable design lets you switch between 35 and 45 liters of space, which is handy for packing light or bringing extra gear. At around 4.5 pounds, it strikes a good balance—not too heavy to carry long but still feeling sturdy. Comfort-wise, it includes padded shoulder straps and a hip belt that can be tucked away for a sleeker look, helping distribute weight during longer carries.

The backpack’s weatherproof 400D recycled nylon shell and solid zippers make it durable enough to handle rough travel conditions without looking bulky. It provides easy access through the top, rear, and sides, so you can grab items quickly without unpacking everything. Organizational features include a laptop sleeve and expandable side pockets for water bottles or tripods, which helps keep items organized and accessible.

Some may find the pack’s 22 x 9 x 13 inch dimensions a bit large for very strict carry-on limits depending on the airline, so it’s good to double-check that. Also, since it’s made with durable materials, it’s not the lightest backpack available, so if ultra-lightweight is your priority, this might feel a bit heavy. Cleaning requires spot treatment, as machine washing is not recommended. This backpack is well suited for frequent travelers who want a tough, adaptable bag with smart organization and weather resistance that can handle both daily use and longer trips.

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.
