Last updated July 2026 · prices and ratings re-checked regularly.
The cheapest backpacks that actually work in 2026 are all three of these MATEIN picks — starting at just $36.99 — and collectively they’ve earned over 95,000 real buyer ratings without a single one dropping below 4.6 stars. This guide is for anyone who refuses to spend $80+ on a backpack but also refuses to watch a zipper blow out at the airport gate. If that’s you, read on. All three bags sit under $46, and the best one costs less than a tank of gas.
To separate the genuinely good cheap bags from the ones that just photograph well, we ran every candidate through the Mavrino Score — a proprietary rating that weights real review volume, verified sentiment, and value-adjusted performance. We also dug into the actual praise and complaints from thousands of owners: what held up after months of daily use, what annoyed people, and whether the gripes were deal-breakers or just minor niggles. The buying factors that mattered most here were organization layout, laptop protection, carry comfort under load, and how the bag handles travel-specific needs like TSA checkpoints and airline size limits.
The shortlist is three MATEIN bags at three price points: $36.99, $39.99, and $45.99. The 15.6-inch Travel Laptop Backpack takes the top spot with a Mavrino Score of 9.7/10 and the largest review base of the three — 42,000 ratings that give it the strongest data confidence we have. The 17-inch TSA model steps up for bigger laptop users, and the 40L carry-on bag is for people who want to skip checked luggage entirely. All three are genuine workhorses at prices that frankly have no business performing this well.
Key Takeaways
- Top pick: MATEIN 15.6-inch at $36.99 — 42,000 reviews, Mavrino Score 9.7/10.
- All three picks score a bias-corrected 4.6★ across 95,000+ combined ratings.
- Spend under $46 and still get TSA-friendly, anti-theft, laptop-ready design.
- The 40L carry-on at $45.99 can replace a checked bag — that’s the surprise win.
- None of these bags are silent — owners consistently flag zipper noise as the one trade-off.
⭐ Our Top Pick
MATEIN Travel Laptop Backpack, Anti-Theft, 15.6-Inch
The best cheap backpack you can buy right now, full stop.
The MATEIN 15.6-inch Travel Laptop Backpack earns its top spot with a 4.6-star adjusted rating across 42,000 reviews — the largest, most statistically reliable sample of the three picks here — and a Mavrino Score of 9.7/10. At $36.99, 87% of buyers say it delivers good value and reliability, and the anti-theft design and dedicated laptop sleeve are features you’d normally pay twice the price to get. The raw numbers are backed by owner sentiment that keeps returning to one word: quality.
⚖️ The honest trade-off: If you carry a 17-inch laptop or want to use your backpack as airline carry-on luggage, step up to one of the other two picks — this bag isn’t built for either of those use cases.

Best Under $40 for Big Laptops
MATEIN 17-Inch TSA-Approved Travel Laptop Backpack
$39.99 ★★★★½ 4.6/5 (38,000 reviews)
★ Mavrino Score: 9.5/10 · Outstanding
The MATEIN 17-inch TSA-Approved Travel Laptop Backpack solves the one problem the top pick can’t: it fits a 17-inch laptop, and it does so for $39.99 — still well inside the budget ceiling most shoppers set. It holds a 4.6-star adjusted rating across 38,000 reviews and a Mavrino Score of 9.5/10, which means it trails the #1 pick by a whisker on data volume but not on quality. The TSA-approved clamshell opening is the practical differentiator here — it lays flat through the scanner without you having to yank out your laptop, which any frequent flyer will tell you is worth every cent of the $3 premium over the base model. Owners echo the same praise: good value, easy to use, reliable day after day. The complaints are identical too — the zippers are louder than expected — so this isn’t a quieter bag, just a bigger one. If your laptop is 17 inches, this is the pick; if it’s not, save the $3 and get the #1.
👤 Best for: Frequent flyers and professionals who carry a 17-inch laptop and want fast, hassle-free TSA screening.
🚫 Skip it if: Anyone who doesn’t need a 17-inch sleeve — the added bulk isn’t justified for smaller machines.
✅ Pro: TSA-friendly clamshell design makes airport security genuinely painless.
⚠️ Consider: Same zipper noise complaint as the rest of the lineup.
Works well overall but louder than expected. Would still recommend for the price.

Cheapest That Replaces a Checked Bag
MATEIN 40L Flight-Approved Carry-On Travel Backpack
$45.99 ★★★★½ 4.6/5 (15,000 reviews)
★ Mavrino Score: 9.0/10 · Outstanding
The MATEIN 40L Flight-Approved Carry-On Travel Backpack is the most ambitious of the three picks, and at $45.99 it’s still a remarkable deal for what it does. A 40-liter flight-approved carry-on that replaces a checked bag starts at $150+ from most travel brands — here you’re getting that functionality for under $50, with a 4.6-star adjusted rating from 15,000 buyers and a Mavrino Score of 9.0/10. The review base is smaller than the other two picks, which is why the Mavrino Score is fractionally lower, but 15,000 ratings is still a solid, high-confidence data set. Owners praise the same trio — good value, ease of use, reliability — and the core promise of fitting in an overhead bin without airline fees is the headline feature that makes this bag genuinely special at this price. The trade-off is that 40L of capacity means more bag to carry, and if you’re not using it for overnight or multi-day trips, the size works against you on shorter outings. The zipper noise complaint shows up here too, consistent across the whole MATEIN range. For weekend trips, light packing travel, or anyone trying to dodge $35 checked-bag fees, this bag pays for itself on the first flight.
👤 Best for: Weekend travelers, light packers, and frequent flyers who want to skip checked-bag fees with a flight-approved 40L bag under $50.
🚫 Skip it if: Daily commuters or students — 40L is overkill for a laptop and lunch, and you’ll feel the extra size.
✅ Pro: Flight-approved 40L capacity that genuinely replaces a checked bag at a fraction of the cost.
⚠️ Consider: Noticeably noisy zippers, same as the rest of the MATEIN lineup.
Really happy with this travel backpack. Does exactly what it says and the quality is excellent.

How to Choose
The single biggest mistake budget backpack shoppers make is treating price as the only filter. A $25 bag that falls apart in three months costs more than a $45 bag that lasts three years. The sweet spot isn’t the lowest price — it’s the lowest price at which the bag stops being a liability. All three picks here clear that bar, which is exactly why they’ve accumulated tens of thousands of positive reviews rather than the angry one-star pile-up that plagues truly cheap bags.
Laptop fit is the spec most people get wrong. The 15.6-inch sleeve on the base MATEIN model fits the majority of consumer laptops sold in the US — if you bought your machine in the last four years and it’s not a gaming laptop or mobile workstation, check the actual dimensions before assuming you need the 17-inch model. Getting the right sleeve size matters because a too-large compartment lets the laptop shift and bounce, which defeats the entire point of having a padded sleeve. The 17-inch bag is genuinely bigger overall, not just a wider sleeve, so if you don’t need that extra clearance, the base model is the smarter buy.
For travel specifically, two specs matter above everything else: TSA compatibility and airline size compliance. The 17-inch model’s clamshell flat-open design is the TSA feature worth paying $3 extra for — having to remove your laptop from a bag in a security line adds stress you don’t need. The 40L model addresses the bigger question of whether your bag counts as a personal item or carry-on. Airline size policies vary, so measure against your specific carrier’s limits before flying — 40L is on the generous end of what most US domestic carriers allow as carry-on, and some budget airlines will flag it. Know your airline’s rules before you board.
Anti-theft features are genuinely useful on budget bags, not just marketing copy. The hidden zip pocket on the back panel of these MATEIN bags sits flush against your body when worn, making it inaccessible to anyone behind you in a crowd. For city travel, commuting on public transit, or any situation where your bag is in a busy environment, this is real protection. It’s not a vault — a determined thief with a blade can still get in — but it eliminates the opportunistic grab that accounts for most travel theft.
Finally, think about the noise. Every owner across all three bags flags zipper loudness as a complaint, and it’s worth taking seriously if you work in quiet environments or travel with a light sleeper. These aren’t whisper-quiet zippers — they’re functional, durable, and loud. If you’re opening your bag in a library, a meeting room, or at 6am in a shared hotel room, you will hear them. It’s the one real lifestyle trade-off across this entire lineup, and no amount of great value changes that acoustic reality.
The Bottom Line
The MATEIN 15.6-inch Travel Laptop Backpack at $36.99 is the single best cheap backpack you can buy in 2026 — 42,000 buyers and a Mavrino Score of 9.7/10 make that a data-backed call, not a guess. If you carry a 17-inch laptop or want TSA-friendly clamshell access, pay the extra $3 for the 17-inch model and don’t look back. And if your real goal is to stop paying checked-bag fees, the 40L carry-on at $45.99 pays for itself the first time you walk past the baggage drop. The bag to skip is any no-name alternative under $20 — you’re not saving money, you’re just buying the same bag twice.
