Best 40L Travel Backpacks
40L Travel Backpacks
40 litre travel backpacks built for carry-on trips across India and beyond. Every 40L backpack in this collection fits airline cabin size limits, includes a rain cover, and opens 180 degrees for suitcase-style packing. The HOBO40 V2.0 is our bestseller with aluminium back support that distributes weight evenly, a detachable waist pouch for your passport and boarding pass, and a padded laptop compartment that fits screens up to 15.6 inches. Whether you are packing for a 5-day trek through Himachal or a week-long work trip across Southeast Asia, a 40 litre backpack gives you enough room without crossing into checked luggage territory. Every bag ships with a rain cover, chest strap, and 2-year warranty.
For 5 to 7 Day Trips Without Checked Bags
One Bag, One Week, Zero Check-In Fees
If you travel with one bag and skip the check-in counter, a 40L backpack gives you exactly enough space for a full week. The HOBO40 V2.0 fits 5 to 7 days of clothes, a laptop, camera, and toiletry kit in one organised bag. Front-panel access means you never dig through the top to find something buried at the bottom. Everything is visible when you unzip, the same way it would be in a suitcase.
Carry-On Compliant on Every Major Airline
The HOBO40 V2.0 meets carry-on limits for IndiGo, Air India, SpiceJet, Akasa, and most international carriers including Emirates, Singapore Airlines, and Thai Airways. You walk straight to the gate, save Rs 500 to Rs 1,500 per domestic flight on checked baggage fees, and never wait at a baggage belt. For business travellers making multi-city trips, this means faster airport exits and tighter schedules without logistical stress.
Built for Long Carries
A fully packed 40L bag hits 8 to 12 kg. Without proper load distribution, that weight destroys your shoulders within an hour. The aluminium back support frame and padded hip belt on the HOBO40 V2.0 transfer the bulk of the load onto your hips, which are built to handle heavy weight. Long layovers, train station walks, and the 20-minute trek from a bus stop to your hostel in Manali stay comfortable instead of painful.
What Sets CarryPro 40L Bags Apart
Front-Panel Access, Not Top-Loading
Most 40L travel backpacks on the market are top-loaders. You stuff everything in from the top and hope you packed in the right order. The HOBO40 opens from the front panel like a suitcase, so you can see and grab anything without unpacking the entire bag. Lay it flat on a hotel bed, unzip, and access your clothes on one side and tech on the other. This single design choice eliminates the daily frustration of digging through a dark top-loading bag for a charger or a clean shirt.
Aluminium Back Support at a Fraction of the Price
An aluminium frame in the back panel is something you usually find in trekking rucksacks priced 3x higher from brands like Deuter and Osprey. It keeps the bag rigid against your back, prevents the load from sagging, and creates a consistent weight distribution point for the hip belt to work properly. Without a frame, a heavy 40L bag slumps and pulls backward, forcing your shoulders to compensate and causing fatigue.
Detachable Waist Pouch for Quick-Access Essentials
The hip belt on the HOBO40 V2.0 includes a detachable waist pouch that holds your passport, phone, boarding pass, and wallet. At immigration counters, security checkpoints, and ticket gates, you reach for your hip instead of unzipping your main bag. Detach it entirely and use it as a standalone fanny pack for exploring a new city once you drop your backpack at the hotel.

Packing Cubes for Internal Organisation
Keep your 40 litres organised with our packing cubes, available in six different sizes that fit the HOBO40 perfectly. Separate your tops, bottoms, underwear, and dirty laundry into individual cubes. On a 5-day trip, you pull out one cube per day instead of rummaging through a mixed pile of clothing. Packing cubes also compress clothes by 20 to 30 percent, giving you extra room for souvenirs on the return trip.
Tech Organiser for Cables and Chargers
Laptop charger, phone cable, power bank, earphones, USB-C adapter, and camera charger. That is 6 items that tangle into one knot if you toss them loose into your bag. The tech organiser keeps every cable in its own elastic loop and every charger in its own pocket. It fits inside the HOBO40's front organiser panel or slides into the laptop compartment alongside your device.
When 40L Is Too Much
Planning a 2 to 3 day weekend trip where 40 litres is overkill? Check our 30L weekend backpacks for a lighter, slimmer option that still opens like a suitcase and fits carry-on limits. The Overnighter 30L gives you the same front-panel access in a more compact package for shorter getaways.
Frequently Asked Questions
Is a 40L backpack allowed as carry-on on Indian flights?
Yes. The HOBO40 V2.0 fits within standard cabin baggage dimensions (55 x 40 x 20 cm) for all Indian domestic airlines including IndiGo, Air India, SpiceJet, and Akasa. The key is staying within the 7 kg cabin weight limit, not the litre capacity. A well-packed 40L bag typically weighs 7 to 9 kg, so you may need to wear your heaviest jacket and shoes to stay under the limit on some flights.
How many days of clothes fit in a 40 litre backpack?
A 40L backpack holds 5 to 7 days of clothes depending on the season. In summer, when clothing is light, you can fit 7 days of outfits plus a toiletry kit, laptop, and charger. In winter, bulkier layers reduce that to 4 to 5 days. Using packing cubes and rolling clothes instead of folding adds roughly 20 to 30 percent more space. For trips beyond a week, plan to do laundry at your destination rather than packing more.
What is the difference between a 30L and a 40L travel backpack?
A 30L backpack is built for 2 to 4 day trips where you want to stay light and mobile. A 40L backpack is for 5 to 7 day trips or longer, carries more clothes and gear, and pushes closer to maximum cabin size limits. The 30L is a better daily-use crossover bag. The 40L is a dedicated travel bag that replaces a suitcase. If most of your trips are weekends, start with 30L. If you regularly travel for a full work week or longer, 40L gives you the room.
Can I use a 40L backpack for trekking?
Yes. The HOBO40 V2.0 has an aluminium back support frame, padded hip belt, sternum strap, and compression straps that make it function as a trekking backpack. For organised treks where the operator provides tents, sleeping bags, and meals (like most Himalayan treks booked through Indiahikes or YHAI), 40L covers all your personal gear. The hip belt transfers weight to your hips for steep ascents, and the rain cover protects your gear during mountain weather.
Does the HOBO40 V2.0 have a laptop compartment?
Yes. A dedicated padded laptop compartment in the rear panel fits screens up to 15.6 inches. The compartment has its own zip access from the back, so you can pull your laptop out at airport security or a cafe without opening the main bag. Foam padding on all sides and a raised base protect your device from drops and bumps during transit.
Does the 40L backpack come with a rain cover?
Yes. Every HOBO40 V2.0 ships with a fitted rain cover that stows in a dedicated bottom pocket. It deploys in seconds when the weather turns and wraps the entire bag in a waterproof shell. The cover is sized to fit the bag at full capacity, so it works whether the backpack is lightly packed for a 3-day trip or stuffed for a full week. You do not need to buy a separate rain cover.
What does 180-degree opening mean on a backpack?
It means the front panel of the bag unzips fully and lays flat, splitting the bag into two halves like an open suitcase. One half holds your clothes flat and compressed, the other holds your tech, documents, and accessories. You see everything at a glance without digging through layers. This is the opposite of a top-loading backpack where you stack items vertically and pull everything out to reach the bottom.
Is 40L too big for everyday use?
Yes, for most people. A 40L backpack is a dedicated travel bag, not a daily commute bag. It is too large and too heavy for carrying just a laptop, lunch, and a charger to work or college. For everyday use, a 20L to 25L backpack like the Mojo V2 or Hobo 25 is the right size. Keep your 40L bag packed and ready for trips, and use a smaller everyday backpack for the other 350 days of the year.
How heavy is the HOBO40 V2.0 empty?
The HOBO40 V2.0 weighs approximately 1.5 kg empty, which is heavier than a basic travel backpack but lighter than trekking rucksacks with similar frame support. The extra weight comes from the aluminium back frame, padded hip belt, and reinforced base panel, all of which pay for themselves in comfort once the bag is loaded to 8 to 12 kg. On a fully packed week-long trip, you will not notice the difference between a 1 kg bag and a 1.5 kg bag, but you will notice whether or not it has a frame.
What is the best 40L travel backpack for international trips?
The HOBO40 V2.0 is built for international carry-on travel. It fits cabin limits for most global airlines, has a rear-access laptop compartment for quick security pulls, includes a detachable waist pouch for passports and boarding passes at immigration, and uses water-resistant fabric with a rain cover for unpredictable weather. The 180-degree opening lets you pack and unpack like a suitcase in hotel rooms and hostels. For multi-country trips across Southeast Asia, Europe, or Japan, it replaces a rolling suitcase with a bag you can carry on your back through cities, trains, and trails.
