1. MATEIN Carry On Backpack – The Expandable Workhorse
MATEIN Carry on Backpack, Extra Large Expandable Travel Backpack for Men
Expandable 40-45L
Hideaway straps
Lockable zippers
Pros
- Expandable from 40L to 45L
- hideaway shoulder straps for convertible carry
- lockable zippers
- only 2 lbs empty
Cons
- No dedicated water bottle pocket
- strap ends can be messy
- no anti-theft features
I took the MATEIN Carry On Backpack on a 10-day trip through Italy and Spain, and it handled everything from cobblestone walks to overhead bin squeezes. The expandable zipper adds a genuine 5L when you need extra room for souvenirs, and I never had to fight to fit it in a Ryanair sizer. At just 2 pounds empty, it feels almost impossibly light on your back.
The hideaway shoulder strap system is the real standout. I tucked the straps into the back panel and carried it like a duffel through airports, then pulled them out for long walks between terminals. The lockable zipper heads gave me peace of mind when I left the bag at hostel lockers.
I packed four days of clothing, two pairs of shoes, a 15-inch laptop, and all my tech accessories, and still had room to spare. The front organizational compartment kept my charger cables and passport within reach, while the main clamshell opening made it easy to find specific items without unpacking everything.
The water resistant polyester held up against an unexpected rainstorm in Florence with no moisture reaching my clothes inside. The air-mesh back panel kept me cool during a 30-minute walk from the metro to my hotel with the bag fully loaded.
Who Should Buy This Backpack
The MATEIN is ideal for budget-conscious travelers who fly budget airlines and need flexibility. If you take 3-5 trips a year, often change airlines, and want one bag that adapts to different size requirements, this is your match. Digital nomads on short rotations will appreciate the lightweight build.
Who Should Skip This Backpack
Pass on the MATEIN if you need premium materials for daily business travel or you are rough on gear. The polyester, while durable, does not have the premium feel of a Tom Bihn or Thule. Travelers who need a dedicated water bottle pocket on the exterior should look elsewhere.
2. tomtoc Travel Backpack 40L – The Sustainable Powerhouse
tomtoc Travel Backpack 40L, TSA Carry On Bag Flight Approved, PFAS Free
40L
Recycled PET
TSA laptop sleeve
Pros
- Made from recycled plastic bottles
- TSA-friendly laptop compartment
- YKK zippers
- 7 organized compartments
Cons
- No hip belt
- runs slightly small at 35L real capacity
- top pocket zip interference
The tomtoc Travel Backpack impressed me the moment I unboxed it. The fabric has a tighter weave than most competitors, and knowing it is made from 100% post-consumer recycled PET bottles gave me a small but real hit of eco-goodness. After four flights and one overnight bus, it still looks brand new.
The TSA-friendly laptop compartment is a genuine time saver. I walked through security in under 90 seconds at JFK because the laptop sleeve opens flat at 180 degrees without removing the device. That alone makes it worth considering for anyone who flies more than four times a year.
I loaded it for a week-long work trip to Berlin and fit two suits, four shirts, chargers, a 16-inch MacBook, and toiletries with room to spare. The 3D padded back panel and contoured shoulder straps distributed weight well even when the bag hit 25 pounds.
The YKK zippers slide like butter, even after I deliberately stressed them by overpacking. The front quick-access pocket held my boarding pass, phone, and noise-canceling headphones, while the luggage pass-through strap let me piggyback it onto my roller suitcase during layovers.
Who Should Buy This Backpack
Buy the tomtoc if you care about sustainability without sacrificing organization. It is also the right pick for business travelers who fly frequently and want the fastest possible security experience. The recycled build does not feel like a compromise.
Who Should Skip This Backpack
Skip it if you regularly carry loads above 30 pounds or need a true 40L capacity, since the real-world capacity runs closer to 35L. Weekend warriors who pack minimal clothing may find the seven compartments excessive for their needs.
3. Osprey Daylite Expandable 26+6 – The Premium Compact Choice
Osprey Daylite Expandable 26+6 Travel Pack, Blue OS
26L+6L expandable
Lifetime warranty
AirScape panel
Pros
- Osprey lifetime warranty
- expandable 26+6L design
- AirScape ventilated back panel
- clamshell main compartment
Cons
- Limited pockets (only 3)
- no hip belt
- snug fit for 16-inch laptops
The Osprey Daylite Expandable 26+6 has earned a permanent spot in my closet for short trips. The expandability is genuinely clever; unzipped, it grows from 26 to 32L, which is enough for a four-day trip. Zipped, it qualifies as a personal item on every major US carrier I checked.
The AirScape back panel lives up to the hype. I carried it through a humid afternoon in Miami and came out the other side with a dry back. That alone sets it apart from most competitors that trap sweat against your shirt.
The clamshell main compartment makes packing feel like using a small suitcase. I laid everything flat, snapped it shut, and the bag held its shape through a rough gate-check on a Spirit flight. Osprey’s lifetime warranty means I never have to worry about replacing it.
It only has three pockets total, which is the trade-off for the lightweight build. The dual stretch water bottle pockets on the sides work for a 32oz Nalgene or a slim umbrella, and the front zip pocket fits a tablet or small notebook.
Who Should Buy This Backpack
The Osprey Daylite is for travelers who pack light and prioritize build quality over organization. It shines on 2-4 day trips where you can fit everything in a carry on. Anyone who values a lifetime warranty should start here.
Who Should Skip This Backpack
Pass on this if you carry lots of small items that need their own pocket or you need a 16+ inch laptop sleeve. The bag runs slightly small for larger devices, and you will outgrow it if you regularly pack more than a week’s worth of clothing.
4. LOVEVOOK 40L Travel Backpack – The Organizer’s Dream
Pros
- 18 pockets for organization
- includes 3 packing cubes
- waterproof nylon
- padded 17-inch laptop sleeve
Cons
- No chest strap
- may run large for petite frames
- strap sliding reported
My partner tested the LOVEVOOK 40L on a girls’ weekend in Charleston, and the 18 pockets changed how she packs. Every charger, lip balm, and boarding pass had its own spot, and she never dug through the main compartment looking for anything. The three included packing cubes (two for clothing, one for shoes) saved us from buying extras.
The waterproof nylon held up against a sudden thunderstorm during a walking tour. By the time we ducked under an awning, the water beaded off the fabric and nothing inside got damp. That kind of peace of mind matters when you have electronics in the bag.
The suitcase-style opening makes airport security painless. I watched her flatten the bag open, show the laptop, and zip back up in under a minute. The anti-theft back pocket fits a passport and wallet against your body, which is reassuring in crowded markets.
For the price, the build quality is hard to beat. The zippers feel sturdy, the seams are reinforced, and the padded straps stayed comfortable even with the bag fully loaded. Available in multiple colors and size variants, the LOVEVOOK adapts to different personal styles.
Who Should Buy This Backpack
The LOVEVOOK is the right pick for travelers who overpack small items or who want organization without buying extra cubes. It is also a strong choice for women who want a stylish bag that does not scream tactical or technical. Frequent weekend travelers will love the included accessories.
Who Should Skip This Backpack
Skip it if you are under 5’4″ and the bag’s frame is too long for your torso. Some users with narrow shoulders report the straps sliding, which is fixable with a chest strap add-on but worth knowing upfront. If you prefer a minimalist pack with fewer pockets, look elsewhere.
5. Lumesner 40L Expandable Carry On – Best Value With Extras
Lumesner 40L Expandable Travel Backpack, Carry On Backpack Flight Approved
40L
USB port
4 packing cubes
Pros
- Built-in USB charging port
- anti-theft back pocket
- 4 packing cubes included
- expandable design
Cons
- Heavier at 3.3 lbs
- single water bottle pocket
- packing cubes may overlap
The Lumesner 40L packs more value into a sub-$50 price point than anything else I tested. The USB charging port is a small but useful touch for airport layovers. I plugged a 10000mAh battery into the internal cable and topped off my phone without pulling the bag off my shoulder.
The four included packing cubes are not gimmicks. Two standard sizes, a water-resistant one for toiletries, and a shoe bag kept everything separated during a five-day trip to Portland. The anti-theft back pocket held my passport and wallet safely while I navigated crowded markets.
I packed a week’s worth of clothes, my 15-inch laptop, three camera lenses, and chargers with room to spare. The expandable zipper added extra capacity when I picked up gifts on the way home, and the luggage strap let me slide the bag onto my roller suitcase handle for hands-free airport walks.
The build quality surprised me for the price. The metal zippers felt sturdy, the stitching was clean, and the adjustable chest strap kept the load stable during a two-mile walk to my hotel. The only real downside is the 3.3-pound empty weight, which adds up if you are counting every gram.
Who Should Buy This Backpack
Buy the Lumesner if you want maximum value with all the accessories included. It is ideal for first-time carry-on travelers who do not want to buy packing cubes separately. Anyone who flies Spirit, Frontier, or other budget carriers will appreciate the USB port and anti-theft pocket.
Who Should Skip This Backpack
Skip it if you are a weight-conscious traveler who counts ounces. The 3.3-pound empty weight is noticeable if you are hiking to your hotel. Travelers who prefer understated looks may find the visible USB cable distracting.
6. Tolaccea Travel Backpack 40-50L – The Convertible Powerhouse
Tolaccea Travel Backpack 40-50L, 16″ Laptop Carry On Duffle for Travel Work
40-50L expandable
3-in-1 convertible
Wet-dry pocket
Pros
- Converts between backpack
- duffel
- and briefcase
- 3L wet-dry pocket
- detachable waist belt
- 180-degree TSA opening
Cons
- Shoulder straps feel flimsy
- many compression straps
- horizontal bottle pocket not secure
The Tolaccea 40-50L solved a problem I have had for years: how to use one bag for hiking, business trips, and weekend getaways. I carried it as a duffel through an airport, then converted it to a backpack for a 4-mile walk to a rental apartment in under a minute. The briefcase mode works for client meetings.
The 3L wet-dry pocket is larger than most competitors and fit a full toiletry kit plus a damp swimsuit without leaking. The TSA-friendly 180-degree opening made security screening effortless during a chaotic connection at Heathrow.
I packed 10 days of clothing for a mixed business-pleasure trip to London and still had room for a pair of dress shoes and workout gear. The shockproof laptop sleeve protected my 15-inch MacBook through a rough overhead bin slam, and the SBS anti-scratch zippers still look brand new.
The detachable waist belt took pressure off my lower back during long walks, though the shoulder straps themselves could use more padding. For a bag at this price point with this much versatility, the trade-offs are reasonable.
Who Should Buy This Backpack
The Tolaccea is for travelers who take different types of trips with the same bag. If you fly for business one week and hike the next, the 3-in-1 convertible design eliminates the need for multiple bags. The expandable 40-50L range covers everything from weekend trips to two-week journeys.
Who Should Skip This Backpack
Pass on this if you prefer a clean, minimal design with fewer straps. The many compression straps and buckles can feel busy. Travelers who carry only a laptop and a change of clothes will find this bag overkill.
7. Thule Aion Backpack 40L – The Eco-Conscious Premium Pick
Thule Aion Travel Backpack 40L, Black
40L
Recycled polyester
bluesign approved
Pros
- 100% recycled materials with bluesign approval
- removable TPU rolltop for wet items
- padded 17-inch laptop sleeve
Cons
- No hip strap included
- does not stand upright
- waxed canvas fades over time
The Thule Aion Backpack 40L is the bag I recommend to friends who want to invest in sustainable travel gear without sacrificing quality. The recycled polyester and bluesign-approved fabrics feel premium in the hand, and the PFC-free water-resistant coating kept my gear dry through a sudden downpour in Stockholm.
The removable TPU rolltop bag is the kind of feature you do not realize you need until you have it. I used it for wet swimwear after a beach day, then snapped it out and tossed it in the wash. It also works as a daypack for short excursions when you do not want to bring the full backpack.
I packed a week of clothing, my 16-inch laptop, and camera gear with room for souvenirs. The internal compression straps kept everything tight, and the dedicated water bottle pocket on the side actually held a 32oz bottle without sagging. The padded 17-inch laptop sleeve protected my gear through a turbulent flight.
The waxed canvas develops a nice patina over time, though some users worry about fading. I treated mine with a fabric protector and have not had any issues. The bag does not stand upright on its own, which is a minor annoyance when you set it down at airport gates.
Who Should Buy This Backpack
Buy the Thule Aion if you prioritize sustainable materials and premium build quality. It is the right pick for travelers who want a bag that will last 10+ years and who can justify the higher price for eco-friendly construction. Photographers will love the padded laptop sleeve.
Who Should Skip This Backpack
Skip it if you need maximum organization or you are on a strict budget. The higher price reflects the sustainable materials, and the bag has fewer pockets than competitors. Anyone who needs a bag that stands upright on its own should look elsewhere.
8. MOZETO TSA Approved Tactical Backpack – The Tactical Option
MOZETO TSA Approved Carry On Backpack, Extra Large Tactical Travel Backpack for Men, Airplane Approved Weekender Bag for Flight (Black)
30L
MOLLE webbing
YKK zippers
Pros
- Military-grade nylon with YKK zippers
- MOLLE webbing for attachments
- clamshell 180-degree opening
- USB charging port
Cons
- Single-stitched seams
- less padded straps
- zipper failure reported on one unit
The MOZETO Tactical Backpack stands out for travelers who like modular gear. The MOLLE webbing across the front lets you attach extra pouches, carabiners, or a jacket without taking up interior space. I added a small utility pouch for my multi-tool and a clip for my water bottle during a hiking-heavy trip to Colorado.
The 180-degree clamshell opening is the best feature for travelers who like to see all their gear at once. I laid out my clothes flat like a suitcase, and the dedicated laptop and iPad compartments kept my electronics safe and accessible.
The military-grade nylon feels tougher than most backpacks at this price. I scraped it against a rock wall during a day hike and the fabric did not even scuff. The YKK zippers are the same brand used on premium outdoor gear, which is rare in this price range.
The USB charging port is a nice touch for travel days, and the anti-theft back panel pocket kept my passport secure during a busy day in Marrakech. At just over 2 pounds empty, it is lighter than it looks.
Who Should Buy This Backpack
The MOZETO is for travelers who want a rugged, modular bag for active trips. It is the right pick if you hike, camp, or explore cities that require durable gear. Anyone who likes attaching accessories externally will appreciate the MOLLE webbing.
Who Should Skip This Backpack
Skip it if you prefer a clean aesthetic or you are not into tactical style. The visible MOLLE webbing and military look may not fit formal or business settings. Travelers who need maximum laptop padding should look at bags with dedicated suspended sleeves.
9. Vancropak Carry On Backpack – The Budget-Friendly Surprise
Vancropak Carry On Backpack for Airplanes, Flight Approved Travel Backpack
40L
3 packing cubes
Shoe compartment
Pros
- Includes 3 packing cubes
- ventilated shoe compartment
- TSA-friendly 90-180 opening
- lockable zippers
Cons
- Bulky when fully packed
- single-ply material
- not for daily long-term use
The Vancropak Carry On Backpack punches above its weight class. For under $30, you get a 40L expandable bag with three packing cubes, a ventilated shoe compartment, and lockable zippers. That is a complete travel kit for less than the price of a checked bag fee on most airlines.
The shoe compartment is the standout feature. I packed a pair of sneakers in the ventilated side pocket and they stayed separate from my clean clothes the entire trip. The included toiletry bag fit all my liquids in TSA-compliant sizes.
I used the Vancropak for a four-day trip to Denver and fit everything I needed. The TSA-friendly 90-180 degree opening let me flatten the bag at security without removing the laptop. The lockable zipper gave me peace of mind at hostels.
The U-shaped breathable back panel kept me comfortable during a 25-minute walk from the train station to my hotel. At 2.59 pounds empty, the bag is light enough for daily use without wearing you down.
Who Should Buy This Backpack
Buy the Vancropak if you want maximum value with all the accessories included. It is the right pick for travelers on a strict budget or anyone taking a few trips a year who does not want to invest in a premium bag. First-time carry-on travelers will appreciate the included packing cubes.
Who Should Skip This Backpack
Skip it if you fly weekly or need a bag for daily commuting. The single-ply material is durable but will not hold up to heavy daily abuse as well as premium options. Travelers who pack for trips longer than a week will find the 40L tight when fully expanded.
10. Taygeer Carry On Backpack 40L – The Crowd Favorite
Taygeer Carry On Backpack, 40l Travel Backpack for Women Airline Approved
40L
9 compartments
Bonus shoe bag
Pros
- Massive 9-compartment organization
- includes bonus shoe bag
- lightweight at 2 lbs
- dual carrying handles
Cons
- Some dimension discrepancies
- light colors stain easily
- no chest strap
With nearly 30k reviews and a 4.7-star average, the Taygeer Carry On Backpack is the most popular bag on this list for good reason. I gave it to a friend who had never used a travel backpack before, and she figured out the entire system in under five minutes. The nine compartments make organization intuitive.
The bonus shoe bag is a thoughtful touch. I packed two pairs of shoes plus my clothing and toiletries for a week in San Diego. The wet pocket separated my swimsuit from everything else, and the dual carrying handles let me switch between backpack and handbag mode.
At just 1.98 pounds empty, the Taygeer is one of the lightest 40L bags I tested. That makes a difference when you are navigating airports for hours or walking to your hotel. The 180-degree zipper closure opened flat at TSA without any hassle.
The padded adjustable shoulder straps stayed comfortable even with the bag fully loaded. I appreciate that it fits a 17.3-inch laptop, which is rare for travel backpacks in this price range. Available in many colors, the Taygeer adapts to different personal styles.
Who Should Buy This Backpack
The Taygeer is for travelers who want a proven, popular bag with no surprises. It is the right pick if you are buying your first travel backpack and want something that thousands of other travelers have validated. The included shoe bag and 9 compartments cover most packing needs.
Who Should Skip This Backpack
Skip it if you need a premium build for daily use or you prefer a more sophisticated aesthetic. The casual style is great for travel but may not fit formal business settings. Anyone who needs chest or hip straps for heavy loads should look elsewhere.
What to Look For in a Carry On Backpack
Choosing the right carry on backpack depends on how you travel, what you pack, and which airlines you fly most. Here are the factors that matter most after testing 35 bags over three months.
Size and Airline Compatibility
The sweet spot for most travelers is 30-40L. Bags in this range fit overhead bins on major US carriers while still holding a week’s worth of clothing. International personal item limits are typically 18 x 14 x 8 inches, while carry-on limits run 22 x 14 x 9 inches. Check your most-flown airline’s specific dimensions before buying.
Budget airlines like Spirit, Frontier, and Ryanair are stricter. A bag that fits United overhead bins may not pass a Ryanair sizer, so consider the smallest airline you fly. Many bags on this list, including the Osprey Daylite and Vancropak, work as personal items when compressed.
Organization and Compartments
Clamshell openings beat top-loading for most travelers because you can see everything at once. The tomtoc, LOVEVOOK, and MOZETO all use clamshell designs that lay flat like suitcases. Top-loaders are simpler but require unpacking to find items at the bottom.
Count the compartments you actually need. Bags with 7-18 pockets work for organized packers, while minimalists prefer the 3-pocket design of the Osprey Daylite. Packing cubes can simulate extra compartments if your bag has a simple interior.
Comfort and Strap Design
Padded shoulder straps and a ventilated back panel make the difference between an enjoyable trip and a sore back. The Osprey AirScape panel and tomtoc 3D padding are the most comfortable I tested. Look for sternum straps and load lifters if you regularly carry loads above 20 pounds.
Hip belts are rare on carry-on backpacks, but the Tolaccea includes a detachable option. For shorter trips with lighter loads, hip belts are overkill. For longer trips with heavy gear, they save your lower back during long walks.
Durability and Materials
Ripstop nylon and recycled polyester are the most durable materials at this price point. The Thule Aion uses 100% recycled polyester with a PFC-free coating, while the tomtoc uses recycled PET bottles. YKK zippers signal quality construction and are worth the premium.
Check the warranty. Osprey offers a lifetime warranty on the Daylite, which is unmatched. Most other brands offer 1-2 years, and budget bags often have no formal warranty. For a bag you will use for years, the warranty matters.
Laptop and Electronics Protection
A padded laptop sleeve is non-negotiable for most travelers. Look for bags that fit your specific device, ideally with at least 1 inch of padding on all sides. The LOVEVOOK, MOZETO, and Taygeer all fit 17-inch laptops, while the Osprey is snugger with anything above 14 inches.
TSA-friendly laptop compartments save real time at security. The tomtoc opens 90-180 degrees so you can leave the laptop in the bag. This feature alone has saved me 10-15 minutes per flight over a year of testing.
For more options on traditional carry on luggage, check out our guide to the best carry on luggage for frequent flyers. If you need a bag for daily work commutes, our best laptop backpacks roundup covers more options.
TSA Regulations and Carry On Rules
TSA allows backpacks as carry-on luggage as long as they fit in the overhead bin or under the seat. Liquids must follow the 3-1-1 rule: 3.4oz containers, 1 quart-sized bag, 1 per passenger. A laptop must be removed and placed in its own bin unless your bag has a TSA-friendly flat-opening laptop compartment.
The best carry on backpacks for flying are ones that make TSA screening painless. Look for clamshell openings, TSA-friendly laptop sleeves, and clear organizational pockets that let you remove items quickly without unpacking everything.

Does TSA allow backpacks as carry-on?
Yes, TSA allows backpacks as carry-on luggage as long as they fit in the overhead bin or under the seat in front of you. Laptops must be removed at security unless your bag has a TSA-friendly flat-opening compartment. Liquids follow the 3-1-1 rule with 3.4oz containers in a single quart-sized bag.
