The best 40L backpack for men depends on where you take it. A hiking pack needs a frame and a hip belt; a travel pack needs a suitcase opening and a laptop sleeve.
We picked the best men’s and unisex 40L packs for both, with a focus on longer torsos and comfortable harnesses.

Detailed Reviews
1The 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)
2The Kestrel LT 35 is a classic top-loading rucksack with a men’s fit and an adjustable torso length, so you can dial it to your back instead of hoping a fixed size works.
Osprey gives it a fixed top lid with a zip pocket, stretch side pockets, a front shove-it pocket, trekking pole attachments and a side zip that reaches into the main compartment without unloading from the top. It ships with a raincover. At 35 liters it is the right size for long day hikes and efficient overnights where you carry a light sleep system.
Pros & Cons
What we like
- Adjustable torso length
- Side-zip access to main compartment
- Raincover included
Watch out for
- Men’s fit only in this listing
- 35L is tight for cold-weather overnights
Key Specs
- Capacity: 35 liters
- Fit: men’s, adjustable torso
- Loading: top lid plus side zip
- Raincover: included
- Extras: trekking pole attachment, shove-it pocket
3The Talon Pro 40 is Osprey’s light, fast multi-sport pack. NanoFly fabric with a triple-grid UHMWPE ripstop gives it strength well beyond its weight, and the stretch pockets are tougher than standard mesh.
It is versatile enough for long day hikes, scrambles, fastpacking and alpine approaches. It has a men’s fit and a hip belt.
Pros & Cons
What we like
- Very strong for its weight
- Durable stretch pockets
- Versatile multi-sport design
Watch out for
- Premium pricing
- Men’s fit only in this listing
Key Specs
- Capacity: 40 liters
- Fabric: NanoFly with UHMWPE ripstop
- Fit: men’s, with hip belt
- Use: hiking, scrambling, fastpacking
4The Thule Landmark 40L is a carry-on adventure travel pack with security features for cities and transit. A hidden CashStash pocket under the SafeZone holds a passport and cash, and LoopLocks secure zipper pulls to deter pickpockets.
It also fits a 15-inch MacBook and a 12.9-inch tablet. It is a strong choice for international trips where theft protection matters as much as capacity.
Pros & Cons
What we like
- Hidden passport and cash pocket
- LoopLocks deter pickpockets
- Laptop and tablet storage
Watch out for
- Premium pricing
- Heavier than ultralight packs
Key Specs
- Capacity: 40 liters
- Security: CashStash, LoopLocks
- Laptop: 15 in MacBook
- Tablet: 12.9 in
5The 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
6Naturehike’s Rock pack combines a 40-liter body with a 5-liter extension, an internal frame, a rain cover and a hydration port. The brand lists it at 22 x 10.2 x 7.1 inches.
Ergonomic shoulder straps and a padded back panel make it a real trekking pack rather than a stretched daypack. Naturehike is a well-known camping brand, and this pack sits between budget no-names and premium Osprey models.
Pros & Cons
What we like
- Internal frame
- 40L plus 5L extension
- Rain cover and hydration port
Watch out for
- Fit range not as adjustable as premium packs
- Fewer reviews than Osprey
Key Specs
- Capacity: 40 + 5 liters
- Size: 22 x 10.2 x 7.1 in (brand listing)
- Frame: internal
- Rain cover: included
- Hydration: compatible
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

How We Chose
We compared published specs, materials, fit ranges and features for more than 40 backpacks in the 30 to 50 liter range, then read verified owner feedback to spot durability and comfort problems that spec sheets miss. We did not receive free products, and we do not claim hands-on testing. TOR Scores combine published specs, verified owner feedback and overall value.
Choosing a 40L Backpack for Men
Men’s-specific packs usually have longer torso ranges, wider shoulder straps and straighter hip belts. For taller men or broad shoulders, a dedicated men’s fit like the Osprey Farpoint 40 or Kestrel LT 35 can be more comfortable than a unisex pack.
- Torso length. Most men fall between 17 and 21 inches. If you are over six feet, check the upper limit.
- Load. If you carry heavy camera gear, climbing kit or water, choose a framed pack with a padded hip belt.
- Style. For travel and work, a clean, dark pack like the Thule Landmark or tomtoc Navigator blends in at the office and airport.
What to Look for in a 40L Hiking Backpack
Forty liters is the sweet spot between a daypack and a full backpacking pack. It holds the Ten Essentials, layers for changing weather, lunch, three liters of water and still has room left for a light sleeping bag on an overnight. Here is what separates a good hiking pack from a big school bag.
- Frame or no frame. Frameless packs (Maelstrom, Nerlion) are light and cheap but feel heavy above about 20 pounds. Internal frames (Osprey, Naturehike, N NEVO) move weight onto your hips and stay comfortable to 30 pounds or more.
- Hip belt. A padded hip belt carries most of the load. A thin webbing strap only keeps the pack from swinging.
- Back ventilation. Mesh or channeled back panels reduce the sweaty patch on hot climbs.
- Rain protection. Most packs are water resistant, not waterproof. A rain cover or a liner bag keeps your sleeping bag and spare clothes dry.
- Hydration. A bladder sleeve and hose port let you drink without stopping, which helps you drink enough.
- Access. Side zips, front shove-it pockets and hip-belt pockets save you from unpacking the whole bag for one item.
For long day hikes, a frameless pack is fine. If you plan to carry a tent, stove and sleeping bag, choose a framed pack with a padded hip belt.
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
How do I know what size backpack I need?
Measure your torso from the C7 vertebra at the base of your neck to the top of your hip bones. Match that number to the pack’s size chart or adjustable range.
Do I need a frame in a 40L backpack?
If you will carry more than about 20 pounds, yes. An internal frame and padded hip belt move weight onto your hips. For lighter day hikes and travel, a frameless pack is fine.
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.
How much should a 40L pack weigh empty?
Frameless 40L packs often weigh around 1 to 2 pounds, while framed hiking and travel packs usually weigh 2.5 to 4 pounds. Wheeled backpacks are heavier, often 4 to 6.5 pounds.
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
For travel, the Osprey Farpoint 40 is the best 40L backpack for men. For hiking, the Osprey Kestrel LT 35 wins, and the Talon Pro 40 is the choice for fast, light days.
