Detailed Reviews
1The LOVEVOOK 40L comes with three packing cubes, so it is ready for a trip out of the box. LOVEVOOK lists it at 18 x 14 x 8 inches and markets it for budget-airline size limits.
Four compartments and many small pockets make it easy to separate clean clothes, electronics and toiletries. It is one of the most popular women’s-styled travel backpacks on Amazon, though the cut and straps are unisex enough for most travelers.

2MATEIN’s carry-on backpack is one of the most widely bought budget travel bags on Amazon. Unzip the expansion panel and it grows to about 45 liters, enough for packing cubes, a toiletry kit and a camera bag.
Unexpanded, it is designed to fit standard overhead bins. It is a soft, simple travel bag, so it suits occasional travelers and weekenders more than people who walk all day with a full load.
Pros & Cons
What we like
- Expands to about 45 liters
- Low cost
- Plenty of organizer pockets
Watch out for

3. 40L Flight-Approved Laptop Travel Backpack
3This 40L travel backpack is a no-frills value pick that fits a 15.6-inch laptop, clothes and daily essentials. It uses high-density polyester with reinforced stitching.
It works well as a work-to-weekend bag. It is a lesser-known brand, so we rank it below tomtoc and Osprey for long-term durability, but it covers the basics at a low cost.
Pros & Cons
What we like
- Fits a 15.6-inch laptop
- Water-resistant polyester
- Low cost
Watch out for
- Lesser-known brand
- No hip belt
Key Specs
- Capacity: 40 liters
- Laptop: 15.6 in
- Fabric: high-density polyester
4Tolaccea’s expandable travel backpack is a value pick for people who travel with a laptop. The 15.6-inch laptop compartment is suspended off the bottom to soften knocks, and it opens from the side so you can grab the laptop without opening the main compartment.
It works as a carry-on, a work bag and a duffel-style weekender. The expansion zip adds room for souvenirs on the way home, though a fully expanded bag may no longer meet stricter carry-on limits.
Pros & Cons
What we like
- Suspended laptop sleeve
- Side access to laptop
- Expands for the return trip
Watch out for
- Expanded size may exceed carry-on rules
- Bulky for daily commuting
Key Specs
- Capacity: 40-50 liters (expandable)
- Laptop: up to 15.6 in, suspended
- Access: side laptop zip
- Use: carry-on, work, weekend
5The Maelstrom 40L is the budget hiking pack we point most first-timers toward. The shell is 210D ripstop nylon, and a rain cover lives in a small pocket under the base, so a surprise shower does not end the day.
It is a frameless daypack-style design, so it carries best below about 20 pounds. Within that range, the padded straps, chest strap and simple hip strap keep it steady on a day hike, a hut trip or a weekend in a city where you walk a lot. Owners mostly praise the pocket count and the value; the main complaint is that the thin hip strap does little to move weight off your shoulders.
Pros & Cons
What we like
- Rain cover stored in a base pocket
- Ripstop nylon resists snags
- Lots of pockets for the money
Watch out for
- Thin hip strap, no frame
- Not for heavy overnight loads
Key Specs
- Capacity: 40 liters
- Fabric: 210D ripstop nylon
- Rain cover: included
- Frame: none (soft back)
- Hydration: bladder-compatible sleeve

How to Get the Most from a Budget 40L Backpack
Budget packs have improved a lot. You can get rain covers, many pockets and even internal frames for much less than a premium pack. Here is how to choose wisely. If you are comparing options, our guide to the best 40L backpack for travel is worth a look.
- Check the stitching and zippers. Reinforced stress points and solid zippers are the biggest durability factors.
- Look for rain covers. They are a cheap way to keep your gear dry.
- Do not overload frameless packs. Keep them under about 20 pounds.
- Read recent reviews. Budget brands sometimes change materials between batches.
For occasional hikers and travelers, a well-chosen budget pack is all you need. If you hike every weekend or carry heavy loads, a premium pack will last longer and carry better. For a different angle, see our picks for the best 40L backpack ultralight.
How to Choose a 40L Travel Backpack
A 40L travel backpack is the classic one-bag size. It holds a week or more of clothes and usually still fits within carry-on limits, so you skip checked-bag fees and baggage-claim waits. For a different angle, see our picks for the best 40L backpack with wheels.
- Carry-on size. Many US airlines allow carry-on bags around 22 x 14 x 9 inches, but international and budget carriers are often stricter. Always check your airline before you fly.
- Clamshell opening. A zip that opens the bag like a suitcase makes packing and finding items much easier than a top-loader.
- Compression. Straps that cinch a half-full bag keep it inside size limits and stop contents from shifting.
- Laptop sleeve. A separate sleeve speeds up security screening and protects your device.
- Harness. Padded straps, a sternum strap and a hip belt make a big difference when you walk from the station to your hotel.
- Security. Lockable zippers and hidden pockets help in crowded places.
Packing cubes turn a 40L bag into a tidy, easy-to-unpack system. Roll clothes rather than fold them, and wear your bulkiest shoes and jacket on travel days. For a closer look, see our guide to the best 40L travel backpack women.
Carry-On Rules for 40L Backpacks
Liters measure volume, not dimensions, so a 40L pack can be either carry-on friendly or too long depending on its shape. Check the listed dimensions, not just the capacity. We cover this in more depth in our roundup of the best 40L travel backpack for women.
- Main carry-on. Many US carriers allow roughly 22 x 14 x 9 inches. Most 40L travel packs are built around that size.
- Personal item. Budget airlines often limit free personal items to about 18 x 14 x 8 inches or less. The LOVEVOOK 40L is marketed for that size, but rules vary by airline and fare.
- Weight limits. Some international airlines cap carry-on weight at 7 to 10 kg. Heavy wheeled bags use up a lot of that allowance before you pack anything.
- Liquids. Keep liquids, gels and aerosols in a quart-size bag in an outside pocket so you can pull them out quickly.
Gate agents care about how the bag looks, too. A compressed, tidy pack that fits the sizer is far less likely to be challenged than an overstuffed one.
