A large travel backpack can save you from checking a bag, but only when its size, structure, and carrying system match your trip. The MATEIN Carry on Backpack, X-Large 40L gives you suitcase-style packing, hideaway shoulder straps, and a light polyester shell at a budget-friendly level. Its main strengths are capacity and flexibility, while its softer structure and basic harness are the key tradeoffs. This review helps you decide whether it suits short trips, overhead-bin travel, and occasional business use.

Key Takeaways

• The linked black X-Large model is a 40L backpack, not the 45L XX-Large version.
• Its 19 x 13 x 8-inch soft-shell design gives you roomy, suitcase-style packing at only 2 pounds.
• Hideaway shoulder straps, top and side handles, and a luggage passthrough make it easy to switch carrying styles.
• Internal and external compression straps help control the load, but the soft structure needs careful packing.
• It is best treated as an overhead-bin carry-on. Under-seat fit depends on the airline, aircraft, and how fully you pack it.

What Is the MATEIN Carry on Backpack?

The MATEIN Carry on Backpack is a soft-shell travel bag built around a clamshell-style main compartment. MATEIN, the consumer-facing brand of manufacturer YoTwo, positions it as an entry-level to mid-range travel pack. The linked ASIN is the black X-Large version with a stated 40L capacity, 19 x 13 x 8-inch dimensions, and a 2-pound empty weight.

You can wear it as a backpack, tuck away the shoulder straps, or use the top and side handles like a soft suitcase. Its main selling point is simple: you get a large packing area and several travel-focused features without moving into the price range of framed or heavily padded travel packs.

Who Should Buy It?

Design and Build Quality

The bag uses lightweight, water-resistant polyester with a soft-shell shape. That keeps the empty weight low and lets the body compress into tight spaces, but it also means the backpack does not stand upright or protect contents like a framed travel pack.

Lockable zipper heads add a useful travel feature when you supply your own small lock. The top and side handles help you lift the bag into an overhead bin, while the hideaway shoulder straps reduce loose webbing when you carry it by hand or slide it onto luggage.

The air-mesh back panel and padded shoulder straps improve comfort for airport transfers. Still, the padding and structure are basic for a 40L load. You will notice the difference most when the bag is filled with dense items such as shoes, electronics, or books. Independent long-term testing of this model has also flagged the lightweight fabric and unbranded hardware as the main question mark for durability over years of heavy use, even though early wear typically stays minor.

Packing and Organization

The full-perimeter opening lets you pack the main compartment more like a suitcase than a school backpack. Internal compression straps hold folded clothing or packing cubes in place, while four external straps help reduce bulging and take pressure off the main zipper.

The current listing describes three compartments and five pockets. The front organizer gives you faster access to items such as a passport, charging cable, earphones, or a small tablet. The large interior works best when you divide clothing and toiletries into packing cubes because the soft walls provide little built-in separation.

The listing also states compatibility with devices up to 17 inches. Because pocket layouts can differ between variants, compare the laptop or device compartment dimensions with your actual case before relying on the bag for a large computer.

Carry Comfort and Convertible Design

The adjustable shoulder straps and sternum strap help stabilize the bag during short walks through terminals, hotels, and parking areas. The straps tuck into a zippered space when you want a cleaner profile, and the side handle lets you carry the bag in a briefcase-style position.

The luggage passthrough is useful when you pair the backpack with a spinner suitcase. You can slide the bag over the suitcase handle instead of carrying all 40 liters on your shoulders. This is a practical advantage because the harness does not include the frame and supportive hip belt found on hiking-oriented travel packs.

Airline Carry-On Fit

At 19 x 13 x 8 inches, the bag is within many common overhead carry-on limits when it is not overstuffed. Airline rules still vary, and a soft expandable bag can measure larger after you fill the front pockets and tighten the compression straps unevenly.

Do not assume it qualifies as a personal item. Many under-seat allowances are smaller than this bag’s stated dimensions, especially on low-cost carriers. Measure the packed bag and compare it with your airline’s current allowance before you leave for the airport.

How It Performs in Real Use

For Weekend Trips

The 40L main compartment gives you enough room for several outfits, toiletries, and a spare pair of shoes when you pack with restraint. The clamshell opening makes it easier to see your clothing than a narrow top-loading backpack.

For Air Travel

The stowable straps and side handle simplify security lines, boarding, and overhead-bin loading. The bag works best as your main carry-on, not as a guaranteed under-seat personal item.

For Business Travel

The black exterior and briefcase-style carry option look restrained enough for casual business trips. Keep electronics in protective sleeves because the lightweight body offers less padding and structure than a dedicated laptop travel bag.

For Long Walking Days

The shoulder and sternum straps are suitable for airport transfers and short walks. For long city walks or heavy loads, a framed pack with a supportive hip belt will distribute weight more effectively.

How to Pack It for Better Comfort

1. Keep dense items close to your back. Place electronics, shoes, and toiletry bags near the back panel instead of at the outer edge.
2. Use packing cubes. The soft interior holds its shape better when clothing is divided into firm rectangular sections.
3. Do not fill every expansion area. Extra bulging can push the bag beyond an airline’s size limit and make the load pull away from your shoulders.
4. Tighten compression straps evenly. Balance the left and right sides so the bag does not twist while you walk.
5. Use the sternum strap. Adjust it high enough to stabilize the shoulder straps without restricting your breathing.

Durability, Water Resistance, and Care

The polyester shell is water resistant, not waterproof. It should handle light rain and small splashes, but seams and zipper openings can still let moisture reach the interior during prolonged exposure.

The lightweight material and unbranded hardware support the low price and low empty weight. They also make the bag feel less substantial than premium luggage. Avoid dragging it, overloading the zipper track, or carrying exposed sharp objects that can stress the fabric.

For cleaning, follow the listing’s care guidance: hand wash or wipe the bag with a damp cloth, and do not machine wash it. Empty every pocket, use mild soap for spot cleaning, and let the backpack air dry completely before storage.

Pros and Cons

Customer Ratings and Feedback

During this August 2026 review update, the Amazon listing showed an average rating of 4.7 out of 5 stars from 14,214 ratings. That makes it a consistently well-reviewed option, but the score covers buyer experiences across a product family that includes several sizes and colors.

Positive feedback commonly centers on capacity, easy packing, and value. The most useful criticism to keep in mind is the soft construction: it gives you more packable space for the weight, but it does not provide the support or polished structure of a higher-end travel backpack.

Warranty and Support

MATEIN publishes a limited lifetime warranty against defects in materials and workmanship. Its policy requires purchase information, and the brand states that warranty registration should be completed within one month of receiving the product. Normal wear, misuse, accidents, fading, tearing from extended use, and expected zipper or buckle wear are not covered.

Return terms depend on where you buy the backpack. The 30-day policy on MATEIN’s website applies to eligible direct purchases, while Amazon return eligibility can vary by seller, order date, and item condition. Check the return window and seller details shown on your order before purchasing.

Is It Worth the Price?

The MATEIN Carry on Backpack sits in the budget travel-pack category. It offers strong value for the price when your priorities are 40L capacity, a clamshell opening, convertible straps, and low empty weight.

You get the most value from it as an occasional travel bag for weekends, holidays, or backup carry-on use. It is not the best fit if you need a highly supportive harness, rigid protection for electronics, or a bag designed for daily long-distance walking.

How It Compares to Alternatives

The Osprey Farpoint 40 is a better comparison for travelers who want an adjustable torso, frame, hip belt, and more supportive load transfer, but it sits in a much higher price tier. The Cotopaxi Allpa 35L offers a more structured, premium travel design with stronger organization and a smaller capacity.

The MATEIN makes the most sense when you want maximum storage and basic travel convenience at a lower cost. Choose a premium alternative when comfort under heavy loads, long-term structure, or technical carry support matters more than price.

Frequently Asked Questions

The Bottom Line

The MATEIN Carry on Backpack is worth considering when you want a light, roomy 40L travel bag with suitcase-style access and several carrying options. Buy it for budget-friendly short-trip organization, but skip it when you need premium structure, heavy-load comfort, or guaranteed personal-item sizing.
