The cheapest backpacks that actually work in 2026 are all made by MATEIN, and that’s not a coincidence — it’s the clearest signal in the budget backpack market right now. If you’re a student, a daily commuter, a weekend traveler, or anyone who refuses to spend $100+ on a bag that might fall apart anyway, this guide is built for you. We’ve cut through the noise to find three sub-$46 backpacks that real buyers are actually satisfied with, not just tolerating.
Every pick here is ranked using the Mavrino Score — our proprietary rating that weighs verified customer sentiment, review volume, price-to-performance ratio, and category-specific factors like organization, durability signals, and travel usability. We also dug into tens of thousands of real buyer reviews across all three products to surface what owners genuinely praise, what quietly frustrates them, and where each bag draws the line between ‘good enough’ and ‘surprisingly great.’ Price alone never drove a pick — value at that price did.
The shortlist runs from $36.99 to $45.99 and covers three distinct sweet spots: a 15.6-inch daily workhorse with the highest Mavrino Score in this roundup (9.7/10), a 17-inch option for bigger laptops and heavier loads, and a 40L flight-approved carry-on for travelers who want to skip checked-bag fees. The $36.99 MATEIN 15.6-inch is the top pick for most people — it earns that position with 42,000 reviews, a bias-corrected 4.6-star rating, and an 87% positive sentiment rate that holds firm at serious scale.
Key Takeaways
- Top pick: MATEIN 15.6-inch at $36.99 — 42,000 reviews, 4.6★, Mavrino Score 9.7/10.
- Best cheap travel bag: the 40L carry-on at $45.99 skips checked-bag fees entirely.
- All three bags score 4.6★ adjusted — price difference buys size, not quality.
- Biggest trade-off across all three: zipper noise, not build quality or durability.
- 87% positive sentiment across the whole lineup — rare consistency for sub-$46 bags.
⭐ Our Top Pick
MATEIN Travel Laptop Backpack, Anti-Theft, 15.6-Inch
The best cheap backpack for most people, full stop — 42,000 buyers can’t be wrong.
The MATEIN 15.6-inch earns a 9.7/10 Mavrino Score because it delivers a bias-corrected 4.6-star rating across 42,000 reviews — that’s not a small-sample fluke, it’s sustained real-world approval at massive scale. At $36.99, it undercuts the competition while matching their adjusted rating exactly, meaning you’re getting the same quality floor for less money. The 87% positive review rate confirms that ‘good value, easy to use, reliable’ isn’t marketing copy — it’s what tens of thousands of owners actually say.
⚖️ The honest trade-off: If your laptop is larger than 15.6 inches, step up to the 17-inch model — cramming a bigger machine into this bag will frustrate you fast.

Best Under $40 for Bigger Laptops — Cheapest 17-Inch Option
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 costs $39.99 — just $3 more than the top pick — and that $3 buys you two extra inches of laptop clearance plus TSA-approved lay-flat design that makes airport security dramatically less annoying. It holds a bias-corrected 4.6-star rating across 38,000 reviews and a Mavrino Score of 9.5/10, essentially matching the top pick in customer satisfaction while serving a different buyer. Owners praise the same core strengths: good value, ease of use, and reliability across repeated use. The 87% positive review rate at nearly 40,000 responses is a confidence signal that’s hard to argue with. The same zipper noise complaint appears here as in the 15.6-inch model — it’s a MATEIN-wide characteristic rather than a defect, but it’s worth knowing before you buy. If your laptop is 17 inches, this is the obvious pick; it’s the cheapest TSA-friendly 17-inch bag on the market with a verified track record at this scale.
👤 Best for: Anyone rocking a 17-inch laptop who flies regularly and wants to breeze through TSA without removing the bag’s contents.
🚫 Skip it if: Buyers who only carry a 15.6-inch laptop — you’d be paying $3 more for space you’ll never use.
✅ Pro: TSA-approved lay-flat design and 17-inch laptop compartment at under $40
⚠️ Consider: Zipper noise is more prominent than buyers expect
Works well overall but louder than expected. Would still recommend for the price.

Cheapest That Lasts on the Road — Best for Carry-On Travel
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 at $45.99 is the priciest of the three, but it’s still one of the cheapest flight-approved 40L bags on the market with a credible review base behind it. It carries a bias-corrected 4.6-star rating across 15,000 reviews and a Mavrino Score of 9.0/10 — lower than the other two picks, but that drop reflects the smaller review pool (15,000 vs 38,000–42,000), not a quality gap. The 87% positive sentiment holds firm across all three products, which tells you MATEIN’s build quality is consistent regardless of which model you pick. The 40L capacity means it fits the personal-item size requirement for most major US carriers, making it a legitimate checked-bag-fee killer for weekend trips and work travel alike. The familiar zipper noise issue appears here too, and at 40L of packed gear you may notice it more when digging through the bag in a quiet space. Travelers who want to skip checked luggage fees entirely — and want to do it without spending more than $50 — have no better option at this price point.
👤 Best for: Frequent travelers who want to carry on everything and avoid checked-bag fees, without spending more than $50 on the bag itself.
🚫 Skip it if: Everyday urban commuters — 40L is overkill for a laptop and lunch, and the extra bulk will wear on you quickly.
✅ Pro: Flight-approved 40L capacity that genuinely replaces a carry-on suitcase at a fraction of the cost
⚠️ Consider: Zippers are louder than expected — a consistent MATEIN characteristic across the lineup
Really happy with this travel backpack. Does exactly what it says and the quality is excellent.

How to Choose
The single most important buying decision in this price range isn’t brand — it’s sizing. A backpack that’s too small for your laptop is useless; a 40L bag for a daily commute is a physical burden you’ll resent by week two. Measure your laptop diagonally before you buy anything. 15.6 inches covers the vast majority of consumer laptops and most Chromebooks. If you’re on a 17-inch gaming laptop or a large Dell or HP workstation machine, the 15.6-inch compartment will reject it outright. Get the 17-inch model. If you genuinely don’t know your laptop size, flip it over — the model number is usually on a sticker, and a quick Google search returns the exact screen size in seconds.
Anti-theft features matter more than most budget-bag buyers expect — until the day they actually matter. The MATEIN 15.6-inch and 17-inch models both include hidden back-panel zipper pockets that press against your spine, making them nearly impossible for someone behind you to access in a crowd. If you commute through a busy city, use public transit, or travel internationally, this is a feature worth prioritizing even at the budget end of the market. At $36.99–$39.99, getting it included is genuinely unusual.
TSA approval is only relevant if you fly — but if you fly even twice a year, it becomes relevant fast. The 17-inch model’s lay-flat laptop compartment means you unzip the bag, lay it flat on the conveyor belt, and walk through without removing your laptop. Anyone who has fumbled with a bag at security while a line builds behind them will understand why this is worth the extra $3 over the base model. The 40L carry-on takes this further: it’s sized to fit overhead bins and under seats on most major US carriers, effectively replacing a checked bag.
Budget backpacks fail at two points: zippers and stitching. The most common complaint across all three MATEIN models in this roundup is zipper noise — they’re louder than buyers expect. This is a functional quirk, not a durability failure; none of the high-volume reviews flag broken zippers as a widespread problem. If you work in a library, a quiet office, or share a bedroom and pack early in the morning, this is worth knowing. It won’t make the bag unusable, but it will mildly irritate you on a weekly basis. Stitching, by contrast, gets consistent praise across the lineup for holding up under regular use.
One mistake budget buyers repeatedly make: choosing the cheapest possible price point when they actually need the next size up. The $3 difference between the 15.6-inch and the 17-inch model is genuinely negligible — but buying the wrong size costs you either a cramped laptop or a bag that flops around empty. Be honest about what you’re carrying daily, add a small mental buffer for the days you pack more than usual, and buy to that realistic load rather than the minimum.
The Bottom Line
The MATEIN 15.6-inch at $36.99 is the single best cheap backpack to buy in 2026 — 42,000 reviews, a 4.6-star adjusted rating, and a 9.7/10 Mavrino Score make it the most validated budget bag in this roundup by a clear margin. If your laptop is 17 inches, spend the extra $3 on the TSA-approved model — same quality, right fit, less airport hassle. Frequent flyers who want to ditch checked-bag fees should step up to the 40L carry-on at $45.99; it’s the most expensive pick here and still one of the cheapest flight-approved 40L bags you’ll find anywhere. The one bag to skip: none — all three deliver, but only if you match the bag to your actual laptop size.
