The travel backpack checklist: 9 things to check before you buy
A good travel backpack passes nine checks: an opening you can pack flat, the right litres for the trip, a laptop sleeve against the back, an empty weight under 800 g, water-resistant fabric, a luggage strap or sleeve, a bottle pocket, a way to separate shoes or dirty clothes, and padded straps. Score any bag against these before you buy. Below, the Fieldwrks Reroute and Teleport are scored honestly.
Key takeaways
- Nine checks decide whether a travel backpack works: opening, litres, laptop sleeve, weight, water resistance, luggage attachment, bottle pocket, dirty-clothes separation and strap comfort.
- The Fieldwrks Reroute (35 L, 780 g) passes all nine, with a clamshell opening, a shoe compartment and a laptop compartment for up to 16 inches.
- The Fieldwrks Teleport (29 L, 795 g) passes eight; it has no separate shoe compartment, so shoes travel in a bag inside the bag.
- Both are soft, frameless flat-fold bags that compress to fit an overhead bin or the space under a seat.
The nine-point travel backpack checklist
Run any backpack for travel through these in order. A bag that fails two of the first four is not a travel bag, whatever the listing says.
- Opening style. A clamshell that unzips fully lets you pack flat and see everything. A top-loader is fine for one or two nights, and worse every night after that.
- Litres for the trip length. 21 to 26 L for a day or one night, 29 L for two nights, 35 L for three to five days. More is not better; it is heavier and it becomes a checked bag.
- Laptop sleeve. Padded, against the back panel, and sized for your actual laptop. A travel backpack with laptop compartment on the front wall puts the laptop where the bag gets knocked.
- Empty weight. Under 800 g. Airlines weigh the bag with your things in it, and every gram of bag is a gram of clothes you cannot bring.
- Water resistance. A water-resistant exterior fabric for the auto ride in the rain.
- Luggage strap or sleeve. A strap or a sleeve on the back that slides over a suitcase handle.
- Bottle pocket. Ideally one that hides or closes, so the bottle does not fall out in the overhead bin.
- Shoe or dirty-clothes separation. A shoe compartment or a divider. Without one, day three's shirt shares space with day one's socks.
- Strap comfort. Ergonomic padded straps. A 6 kg bag on thin straps is a bad hour between the station and the hotel.
How many litres does a travel backpack need?
Litres are the check people get wrong most often, in both directions. The table pairs trip length with capacity and with the Fieldwrks pack that fits it. Every Fieldwrks bag is a lightweight travel backpack by the weight check above; the difference is litres and opening.
| Trip | Litres | Fieldwrks pack | Weight | Opening |
|---|---|---|---|---|
| Day trip | 21 L | Sidewalk | 700 g | Wide-access bucket |
| One night | 26 L | Pitstop or Switch | 620 g or 805 g | Bucket (Pitstop); flat-fold with tote handles (Switch) |
| Two nights | 29 L | Teleport | 795 g | Top-loading, flat-fold |
| Three to five days | 35 L | Reroute | 780 g | Clamshell, zips fully open |
For what 35 L actually holds in shirts, shoes and a toiletry kit, the 35-litre guide lays it out item by item.

Fieldwrks Reroute780 g · 35 L · 16" laptop
₹3,699How does the Reroute score?
The Fieldwrks Reroute backpack passes all nine. Honest notes on each.
- Opening: clamshell. The 35 L main compartment zips completely open and lies flat like a suitcase. A built-in mesh divider holds one side down.
- Litres: 35 L. Three to five days, or a wedding weekend with two outfits.
- Laptop: a padded tech compartment for up to 16 inches, the largest sleeve in the Fieldwrks range.
- Weight: 780 g. Lighter than the smaller Teleport, which tells you where the money went.
- Water resistance: Aerology™ nylon, a feather-light, water-resistant exterior with a polyester lining.
- Luggage: a built-in luggage strap for a suitcase handle.
- Bottle: a hidden zippered side pocket.
- Separation: a dedicated shoe compartment, plus the mesh divider.
- Straps: plush, ergonomic padded shoulder straps.
The one thing to know is what it is not. Reroute is a clamshell travel backpack; it does not convert into a tote. In 2026 it comes in VCR Blue, Robo Black and Dad Brown.
How does the Teleport score?
The Fieldwrks Teleport backpack passes eight of nine, and the miss is a fair one.
- Opening: top-loading and flat-fold. Fine for two nights. You will not pack it flat on a bed.
- Litres: 29 L. Two nights of clothes around a laptop.
- Laptop: a padded sleeve for up to 15.6 inches.
- Weight: 795 g.
- Water resistance: the same Aerology nylon.
- Luggage: a full luggage sleeve rather than a strap.
- Bottle: a hidden zippered side pocket.
- Separation: no shoe compartment. A top mesh zip pocket separates small things, and shoes go in a cloth bag inside the main compartment.
- Straps: plush, ergonomic padded shoulder straps.
Teleport is the travel backpack with compartments for people who do not pack shoes: dual vertical front zip pockets for documents and a charger, two internal slip pockets and two pen loops. The weekender backpack guide is built around it.
Is a travel bag for men different from a travel backpack for women?
No. The labels are a search habit, not a design category. A travel bag for men and a travel backpack for women are the same bag if they pass the same nine checks. What actually changes fit is torso length: a shorter torso wants the bag's base to sit above the hips, which means a shorter bag or a tighter strap adjustment, not a different colour.
Three things to check instead of the label: the strap padding does not dig into the collarbone, the straps do not slide off the shoulders when pulled tight, and the bag's base does not bounce on the lower back when you walk.

Fieldwrks Teleport795 g · 35 L · 15.6" laptop
₹3,699Flying with a travel backpack in India
Both Reroute and Teleport are soft, frameless, flat-fold bags. That matters on an IndiGo or Air India flight because a frameless bag squashes to fit the overhead bin or the space under the seat, where a framed bag of the same litres would not. Pack the laptop last so it comes out first at security, weigh the packed bag on the bathroom scale before you leave, and keep the bottle pocket empty until you are through.
The airlines publish their own cabin limits and change them, so confirm with the airline before you fly. The cabin bag size cheat sheet has the current figures for IndiGo, Air India and Akasa in one table.
Frequently asked questions
What is the best travel backpack in India for a 3-day trip?
A 35 L clamshell with a shoe compartment, which is the Fieldwrks Reroute: 780 g, a 16-inch laptop compartment, a mesh divider and a hidden bottle pocket. It packs flat like a suitcase and separates shoes from clothes, which are the two things that matter most from the third day onward.
Does a travel backpack need a laptop compartment?
If a laptop is coming, yes, and it should sit against the back panel. A laptop loose in the main compartment gets hit by every wall you lean the bag against. Every Fieldwrks pack has a dedicated sleeve: up to 15.6 inches on four of them and up to 16 inches on the Reroute.
Can I use a travel backpack as cabin baggage?
Usually, if it meets the airline's weight and size limits, which change and should be confirmed before flying. Soft, frameless bags such as the Reroute and Teleport compress to fit, and empty weights of 780 g and 795 g leave most of a 7 kg cabin allowance for your things.
Which is better for travel, a clamshell or a top-loading backpack?
Clamshell for anything over two nights. It unzips fully so you pack flat and see everything, and a divider keeps one side in place. Top-loading bags are simpler and fine for a night or two, but every item below the top one has to be dug for.
Score your current bag against the nine. If it fails on opening or separation, the Reroute fixes both; if it only fails on weight, either fixes that, and the Teleport is the smaller of the two.
