Detailed Reviews
1This version of the Maelstrom swaps to a more water-resistant fabric and spreads storage across nine pockets: the main compartment, two front zip pockets, two hip-belt pockets, two side pockets and two mesh pockets.
The brand lists the pack at about 13.4 x 8.6 x 22 inches, a tall and narrow shape that stays close to your back on narrow trails and in crowded train aisles. Hip-belt pockets are the standout here; snacks, a phone and a map stay reachable without stopping. Like the standard Maelstrom it has no real frame, so treat it as a big daypack rather than an overnight hauler.
Pros & Cons
What we like
- Two hip-belt pockets for snacks and phone
- Water-resistant fabric
- Slim profile for trails and transit
Watch out for
- No frame for heavy loads
- Back panel runs warm in summer
Key Specs
- Capacity: 40 liters
- Size: about 13.4 x 8.6 x 22 in (brand listing)
- Pockets: 9 including 2 hip-belt pockets
- Fabric: water-resistant nylon
- Frame: none
2The tomtoc Navigator-T66 is a structured, carry-on travel backpack with a separate laptop compartment and lots of internal organization. tomtoc lists it at 20.47 x 12.99 x 9 inches, with usable capacity of about 38 to 40 liters depending on how you pack.
It is built for flights and cities, not trails: think airline cabin bag with good straps rather than a hiking pack. The fabric is PFAS-free, and the stiff sides hold their shape so packing cubes slide in and out easily.
Pros & Cons
What we like
- Dedicated laptop compartment
- Structured shape suits packing cubes
- PFAS-free materials
Watch out for
- Not built for hiking
- Heavier than soft travel packs
Key Specs
- Capacity: about 38-40 liters
- Size: 20.47 x 12.99 x 9 in (brand listing)
- Laptop: separate compartment
- Materials: PFAS-free
3The 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.
Pros & Cons
What we like
- Three packing cubes included
- 18 x 14 x 8 in footprint
- Lots of small pockets
Watch out for
- Soft back, no frame
- Organization can feel busy
Key Specs
- Capacity: 40 liters
- Size: 18 x 14 x 8 in (brand listing)
- Extras: 3 packing cubes
- Compartments: 4 plus pockets
4The adidas Excel 6 is a 40L school backpack with LoadSpring shoulder straps that soften the bounce of a heavy book load. An interior sleeve holds up to a 15-inch laptop.
The material wipes clean with soap and water, and adidas backs it with a lifetime warranty. It is our top pick for high school and college students who need room for books, a laptop and gym clothes.
Pros & Cons
What we like
- LoadSpring straps ease heavy loads
- 15-inch laptop sleeve
- Lifetime warranty (brand)
Watch out for
- Basic back panel
- Not a travel bag
Key Specs
- Capacity: 40 liters
- Laptop: up to 15 in
- Straps: LoadSpring
- Warranty: lifetime (brand)
5The Farpoint 40 is one of the most recommended one-bag travel packs for good reason. It meets most carry-on size limits, opens wide like a suitcase, and has a real load-lifting frame with a men’s-specific harness.
WingJacket compression straps cinch the pack down when it is not full, a direct-zip 3-1-1 pocket keeps liquids ready for the security line, and front and bottle pockets handle quick-grab items. It is not cheap, but it carries better than most travel backpacks because it borrows its suspension from Osprey’s hiking packs.
Pros & Cons
What we like
- Suitcase-style opening
- Real frame and hip belt
- 3-1-1 liquids pocket for security
Watch out for
- Premium pricing
- Hip belt adds bulk in the overhead bin
Key Specs
- Capacity: 40 liters
- Fit: men’s-specific
- Frame: load-lifting
- Compression: WingJacket
- Carry-on: meets most limits (check your airline)
6The Loowoko is a 50L budget pack that gives you an extra 10 liters over the 40L class for bulky winter layers or a sleeping bag. The upgraded version has stronger straps, sturdier zippers and an included rain cover.
It is one of the most reviewed budget hiking backpacks on Amazon. We include it as a stretch option for anyone who thinks 40 liters will be tight, especially for cold-weather or shared-gear trips.
Pros & Cons
What we like
- Extra room over 40L
- Rain cover included
- Machine-washable per brand
Watch out for
- Bigger than many need
- Soft back, limited load transfer
Key Specs
- Capacity: 50 liters
- Rain cover: included
- Care: machine wash (brand)
- Frame: none
7The Nerlion 40L is a simple, light hiking and travel pack. Nerlion lists the bag at 0.9 kg, and the thick nylon is treated to resist water and abrasion.
One main compartment, several zip front pockets and two side pockets keep it easy to pack. It is a good all-rounder for students, casual hikers and travelers who want one bag for many uses without spending much.
Pros & Cons
What we like
- Light for a 40L pack
- Water-resistant nylon
- Simple, easy layout
Watch out for
- No frame
- Basic hip strap
Key Specs
- Capacity: 40 liters
- Weight: 0.9 kg (brand listing)
- Fabric: water-resistant nylon
- Pockets: main, front zips, 2 side
8The 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.
- 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.
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.
- 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.

Frequently Asked Questions
Are cheap 40L backpacks worth it?
For occasional hikes and travel, many budget packs work well. Check the stitching, zippers and recent reviews, and do not overload frameless designs.
Is a 40L backpack carry-on size?
Many 40L travel packs are designed around common carry-on limits of about 22 x 14 x 9 inches, but airlines differ. Check the listed dimensions and your airline’s rules, and compress the pack before you fly.
Are 40L backpacks waterproof?
Most are water resistant rather than waterproof. Seams and zippers let water in during heavy rain. Use a rain cover or a liner bag for anything that must stay dry.
How many days of travel can a 40L backpack hold?
With packing cubes and quick-dry clothes, most people fit five to seven days of clothes in 40 liters, which works for longer trips if you do laundry along the way.
How do I clean a backpack?
Empty it, shake out debris, and hand wash with mild soap and lukewarm water. Avoid the washing machine unless the brand allows it, and air dry away from direct heat.
Final Verdict
On Amazon, the Maelstrom 40L Waterproof is the best budget hiking pick, the tomtoc Navigator-T66 is the top carry-on, and the Osprey Farpoint 40 is worth the premium if you travel often.
