MATEIN $36.99 vs $45.99 Backpack: Cheapest vs Most Expensive Backpack in 2026
Disclosure: Mavrino earns commissions from qualifying purchases made through links on this page. This does not affect our recommendations.
The cheapest vs most expensive backpack in 2026 debate doesn’t always mean a huge price gap — but even a $9 difference matters when you’re deciding between two very similar bags. The MATEIN Travel Laptop Backpack sits at $36.99 and earns a Mavrino Score of 9.7/10 across 42,000 reviews. The MATEIN 40L Flight-Approved Carry-On comes in at $45.99 — $9 more — with a Mavrino Score of 9.0/10 across 15,000 reviews. Both carry identical adjusted ratings of 4.6/5 and identical 87% positive review rates. The real question is whether the extra capacity and flight-approved carry-on sizing justify that price jump for your specific travel style.
For most people — daily commuters, weekend travelers, students — the $36.99 laptop backpack is the clear buy. It has three times the review volume, a higher Mavrino Score, and does the core job (laptop protection, anti-theft features, organized carry) without the bulk of a 40L bag. The $45.99 version earns its price only if you routinely need to pack for multi-day trips and want a single bag that clears airline carry-on rules. If that’s not you, the extra $9 buys you volume you’ll never use.
⭐ Our Recommendation
MATEIN Travel Laptop Backpack, Anti-Theft, 15.6-Inch
Buy the $36.99 MATEIN — higher Mavrino Score, triple the reviews, same daily performance.
The $36.99 MATEIN scores 9.7/10 on Mavrino — 0.7 points higher than the pricier model — and is backed by 42,000 reviews versus 15,000, giving far greater confidence in that 4.6-star adjusted rating. For anyone who isn’t specifically packing for a multi-day trip without checked luggage, the extra 40L capacity of the pricier bag adds weight and bulk that works against you, not for you.
⚖️ Pick the other one if: If you travel carry-on only for trips of two nights or more and need every cubic inch of airline-approved space, the $45.99 40L is the smarter buy.

Head-to-Head
| Category | MATEIN Travel Laptop Backpack, Anti-Thef | MATEIN 40L Flight-Approved Carry-On Trav |
|---|---|---|
| Price | $36.99 | $45.99 |
| Capacity & intended use | Laptop daypack with anti-theft design, built for 15.6-inch laptops and daily carry | 40L carry-on sized for multi-day travel and flight cabin compliance |
| Ease of use | Praised for straightforward organization and intuitive layout | Same core praise, but more compartments in a larger frame can mean more fumbling |
| Noise level | Flagged as louder than expected by some owners — zippers and fabric rustle noted | Same complaint surfaces in reviews — ‘louder than expected’ appears in both datasets |
| Cleaning | Standard wipe-down materials; no special cleaning instructions flagged positively or negatively | Larger surface area means more to wipe down after travel; no meaningful difference in material |
| Value for money | 9.7/10 Mavrino Score at $36.99 — the strongest value proposition in this comparison | 9.0/10 Mavrino Score at $45.99 — solid value, but only if you actually use the 40L capacity |
MATEIN Travel Laptop Backpack, Anti-Theft, 15.6-Inch
$36.99 ★ 4.6/5
The MATEIN Travel Laptop Backpack at $36.99 is the best-validated budget backpack in this comparison — 42,000 reviews at an adjusted 4.6/5 and a Mavrino Score of 9.7/10 is a rare combination of volume and quality. Owners consistently praise how well it does the basics: the 15.6-inch laptop compartment is snug and protective, the anti-theft features (hidden zippers, lockable design) work exactly as described, and the organization layout is intuitive enough that you stop thinking about it after day one. The standout strength is straightforward reliability — 87% of verified buyers rate it positively, and the most common 5-star phrase is simply that it ‘does exactly what it says.’ The honest limitation: the zippers and fabric generate more noise than you’d expect from a bag at this price, and a handful of buyers found the setup instructions unhelpfully vague.
👤 Best for: Daily commuters, students, and weekend travelers who carry a 15.6-inch laptop and want a reliable, organized bag without paying for capacity they don’t need.
“Really happy with this travel backpack. Does exactly what it says and the quality is excellent.”

MATEIN 40L Flight-Approved Carry-On Travel Backpack
$45.99 ★ 4.6/5
The MATEIN 40L Flight-Approved Carry-On at $45.99 earns its price for a specific traveler — one who packs for two-plus nights and refuses to check a bag. It carries a Mavrino Score of 9.0/10 across 15,000 reviews at an adjusted 4.6/5, which is strong, though the smaller review base makes that rating slightly less certain than the cheaper model’s 42,000-review dataset. The 40L capacity is the headline feature: it’s built to meet standard airline carry-on dimensions, meaning it can replace both a personal item and a checked bag for short trips. Owners echo the same core praise as the cheaper bag — good value, easy to use, reliable — which tells you these two bags share DNA; you’re paying $9 for volume, not a step up in build quality. The same noise complaint (louder zippers than expected) and unclear instructions surface here too, so don’t expect a premium feel at this price.
👤 Best for: Frequent carry-on-only travelers, light packers doing 2–4 night trips, and anyone who needs to consolidate their luggage into one flight-approved bag.
“Works well overall but louder than expected. Would still recommend for the price.”

The Verdict
The $9 price gap between these two MATEIN bags is real, but what it buys you is capacity — not quality. Both bags score an identical adjusted 4.6/5, share the same 87% positive rate, carry the same praise, and suffer the same complaints. The $36.99 laptop backpack edges out the $45.99 carry-on on pure value with a Mavrino Score of 9.7 versus 9.0, and its 42,000-review foundation makes that rating the more trustworthy of the two. For the vast majority of buyers — daily commuters, students, anyone not specifically traveling carry-on only — the cheaper bag is the correct call.
The $45.99 40L earns its premium only in one specific scenario: you travel without checked luggage for multi-night trips and need a single bag that won’t get gate-checked. If that describes you, the extra $9 is a legitimate investment. If it doesn’t, you’re paying for 40 liters of space you’ll leave empty. Buy the $36.99 bag, save the $9, and spend it on something you’ll actually use.
Frequently Asked Questions
Is the $9 price difference between these two MATEIN backpacks worth it?
Only if you specifically need carry-on-sized capacity for multi-night trips. Both bags have the same 4.6-star adjusted rating and 87% positive reviews. The cheaper $36.99 model actually scores higher on Mavrino (9.7 vs 9.0), so you’re paying for volume, not quality.
Does the MATEIN 40L actually fit in an airplane overhead bin?
It’s marketed as flight-approved carry-on size, which is its core selling point over the cheaper model. That said, airline size rules vary by carrier — always check your specific airline’s carry-on dimensions before flying.
Why does the cheaper MATEIN have a higher Mavrino Score than the more expensive one?
The $36.99 bag has 42,000 reviews versus 15,000 for the $45.99 model — triple the data. Higher confidence in a consistent 4.6-star rating across a much larger sample directly lifts the Mavrino Score, which factors in review volume and reliability, not just the star rating.
Both bags have the same complaints — is that a problem?
The shared complaints (noise, unclear instructions) are minor and appear in a small fraction of reviews given the 87% positive rate on both. Neither issue is a dealbreaker, but if you need a near-silent bag for a library or quiet office, factor that in before buying either.
