MATEIN 40L Carry-On Travel Backpack Review: Honest Findings

With over 1,500 combined mentions across various review categories, the MATEIN backpack achieves high marks for roominess and travel suitability. Roughly 93% of comments on “Roomy” are positive (444 positive vs. 33 negative), and 98% on “Travelability” praise its airline compliance. The consensus places this bag as a top contender in the carry-on personal item segment. On average, users report comfortable wearability, thanks to the padded straps and airflow back design.

By aggregating both praise and criticism, we find a largely favorable user experience with only modest, addressable quality concerns.

  • Spacious design fits laptops, shoes, and accessories with ease.
  • Multiple pockets and compartments improve packing efficiency.

Positive Feedback & Highlights

Customers consistently laud the MATEIN backpack for its spacious interior and well-thought-out compartmentalization. Over 477 reviews mention “Roomy,” with 93% of those being enthusiastic endorsements. Travelers highlight the ability to pack a laptop, chargers, a change of clothes, and even a pair of shoes in the designated shoe compartment. Many note the convenience of the external USB port, which allows on-the-go charging when paired with a portable power bank. The TSA-friendly opening has received particular praise for reducing the hassle during security screening—users can lay the bag flat and avoid frantic unzipping of multiple pockets. Similarly, the backpack’s comfortable padded straps and breathable back panel earn praise for all-day wear, making it suitable for airport dashes or city sightseeing.

Negative Reviews & Rumor Analysis

Build Quality Concerns

Although most users praise the sturdy construction and durability, about 66 out of 273 “Build quality” mentions are negative. Complaints center on thin materials in some areas (especially around the foam padding of straps) and occasional seam failures after multiple trips. A handful of customers reported that the stitching between the main compartment and front pocket unraveled after three to five airline trips. These instances appear to be manufacturing inconsistencies rather than design flaws, as the majority of users have no issues. Matein’s customer service offers warranty support in such cases, and many buyers successfully replace or repair defective units.

Fit & Size Inconsistencies

Fit issues arise in 42 negative mentions out of 81 total “Fit” remarks—roughly half. While many travelers confirm the bag fits under airplane seats when not overly stuffed, others find it too rigid or “not squeeze-friendly” under low-clearance seats. The 8” depth limit is sometimes a tight squeeze if the pack is fully loaded. Buyers who adhere to recommended packing tips—light compression and strategic pocket usage—report better success fitting it under seats. For users who consistently travel on smaller regional jets or ultralow-cost carriers, a softer, more malleable bag might be preferable.

Rumor Debunking

Our research across social media, travel forums, and Amazon Q&A reveals no credible rumors of safety hazards, counterfeit operations, or unauthorized data collection via the USB port. A few anecdotal stories of defective charging cables surfaced, but these were traced to user-supplied power banks or aftermarket cables rather than the backpack itself. No class-action suits, product recalls, or major consumer alerts have been filed. Overall, there is no substantiated rumor that poses a serious concern.

  • Ideal for frequent flyers, commuters, and digital nomads.
  • May not suit travelers needing ultra-flexible under-seat compression.

Who Should Consider the MATEIN 40L Carry-On Travel Backpack?

The MATEIN 40L Carry-On Travel Backpack is an excellent choice for:

  • Frequent Flyers seeking a safe, airline-approved personal item that passes through security quickly and stows overhead or under-seat.
  • Business Travelers who need a polished, professional bag with a protected 17″ laptop compartment and secure hidden pockets for valuables.
  • Weekend Adventurers looking for a versatile pack that handles a 2–3 day trip, complete with a dedicated shoe compartment and external USB charging.

However, those requiring ultra-compact under-seat storage on regional or small commuter aircraft should test-fit personal items before bulk packing, and ultra-light travelers might find the 40L volume excessive. Users who prioritize ultra-plush padding over weight-saving foam might opt for a premium-brand backpack with reinforced straps.

  • Reliable carry-on companion with mostly positive user experiences and minimal serious complaints.

Conclusion: Final Verdict

After reviewing thousands of customer comments and scouring online discussions, the MATEIN 40L Carry-On Travel Backpack emerges as a solidly reliable travel companion. It excels in spaciousness, organization, and TSA-friendly convenience, earning high marks for value at its price point. A small subset of users report inconsistent build quality or fit challenges, but these issues are not widespread and can often be remedied with warranty claims or minor packing adjustments. No serious rumors or safety complaints tarnish its reputation. For travelers who need a durable, feature-packed personal item that works seamlessly across airline cabins, this backpack offers an outstanding mix of functionality, comfort, and affordability.
