10 Best Carry On Backpacks 2026 in the United States

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 Thule Aion Travel Backpack 40L is designed to be a reliable carry-on option for travelers who need a mix of durability, organization, and comfort. Its 40-liter capacity is generous, making it suitable for short trips or those who like to pack a bit extra. The backpack weighs about 1.45 kg, which is moderate—not too heavy but not ultra-light either, so it should be comfortable enough for carrying through airports or on day trips. Comfort is enhanced by padded shoulder straps and compatibility with an optional sling bag that can act as a hip belt, helping distribute weight better on longer hauls.

Durability is a strong point here; the materials include 100% recycled polyester with a water-resistant coating and waxed canvas, which offers good protection from rain and wear. The fabric’s natural, slightly broken-in look may show minor marks, but this adds character rather than detracts from quality. Organization-wise, the backpack scores well with multiple pockets, including a padded compartment for laptops up to 17 inches, an internal zipped pocket for small essentials, a dedicated water bottle holder, and compression straps to keep items secure during travel. A unique feature is the removable TPU rolltop bag inside, which prevents moisture or odors from spreading to the rest of the backpack—handy for toiletries or dirty clothes.

One consideration is that the backpack’s water resistance is good but not fully waterproof, so heavy rain might require extra protection. Also, the material requires hand washing, which might be less convenient for some users. While it meets most airline carry-on size requirements, its rectangular shape and 40L volume might feel large for minimal packers or those seeking a slimmer profile. This backpack offers a solid blend of eco-friendly materials, thoughtful organization, and casual style, ideal for travelers who want durability and practical features without opting for a bulky or complicated bag.

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.
