A laptop backpack is the bag most people carry most days, and the shelf is sold on two words that mean less than they sound. Seventeen bags and three padlocks are on this page, and the useful numbers are on a minority of the titles.

The laptop, and why the sleeve is the whole fit

A laptop sleeve is a padded pocket sewn to a size. Nine titles here state that size: 14, 15.6, 16.2, 17 and 17.3 inches. The other eight say laptop and leave the number out.

A 15.6-inch sleeve fits a 15.6-inch Windows laptop. It does not fit a 16-inch MacBook Pro, which is wider, and one title here has noticed that and says 16.2 by name. Measure your laptop’s width and depth, not its screen, and buy a sleeve that states a size that covers it. A bag that says laptop without a number is a bag you may be sending back.

Litres, on one title

Capacity is how a backpack is actually sized, and one title here gives it: 39 litres. The rest say large capacity, or nothing.

For scale: 20 to 25 litres is a commute, laptop, lunch and a jumper. 30 is a commute with the gym. 35 and up is a night away, and a 39-litre bag on a train every day is a bag that is mostly air. If the listing photographs show a dimension in centimetres, height times width times depth divided by a thousand is the litres, near enough.

What anti-theft means on a bag

Fourteen titles say anti-theft. On a backpack the phrase means one thing: the main zip opens against your back, so that a hand in a crowd behind you cannot get into it without taking the bag off you. That is a real design and it works for what it is.

What it does not mean, on any title here, is cut-resistant fabric, lockable zip pulls, a hidden pocket or a steel cable. Those exist and none of these twenty says it has them. The one bag that has a mechanism is the WiWU, with a fingerprint lock on the main compartment. The three padlocks sold beside the bags, one with a three-digit combination and a cable, one a certified luggage lock, one a fingerprint padlock that pairs to a phone, are the other honest answer: anti-theft is a lock, and a lock costs a few pounds extra.

The USB port

Three titles have a USB port on the strap. It is a short cable through the fabric that runs from a socket outside to a plug inside, where you put a power bank you already own. It charges nothing by itself, it is one more hole in a bag that says waterproof, and it saves you the trouble of running a cable out of the top. Treat it as free rather than as a feature, and never as a reason to pay more.

Waterproof, water resistant, and the rain

Six titles say waterproof or water resistant, and they use the two words as if they were one. A backpack with a zip is water resistant at best: the fabric sheds a shower and the zip lets a downpour in. None of the six gives a rating, and none mentions a rain cover, which is the thing that actually keeps a laptop dry on a wet walk. If you cycle or walk in rain, buy the cover separately whatever the title says.

Nine names

Nine of these twenty titles carry a maker’s name, which is more than most shelves on this site manage. Tigernu, Mark Ryden, BOPAI, OZUKO and WiWU are bag makers with catalogues you can look up. Heroic Knight and HK are the same maker, three times. A name is a size chart with real centimetres in it, a stated weight, and somewhere to send a bag when a zip fails, and on this shelf it is worth a pound or two.

One title says cowhide, which is leather, and two say oxford or PVC, which are the two cloths most of these are made of whether they say so or not. Oxford is the woven nylon that most rucksacks are; PVC is a coated fabric that wipes clean and is heavier.

What none of them says

Weight. Six titles say lightweight and none gives grams. An empty laptop backpack is somewhere between 700 grams and a kilo and a half, and you carry the difference every day.

A trolley sleeve. None. The strap on the back that slides over a suitcase handle is the difference between a bag you can travel with and one you cannot, and no title mentions it.

Chest or waist straps. None. For a 39-litre bag with a laptop in it, that is a missing answer.

The card holder guide covers the other thing on this shelf that is sold on a word rather than a number.

What I would actually do

For most people, the Tigernu. A maker’s name, the laptop size, the litres: it is the only title on the page that states all three, and 39 litres is big enough to be the one bag for a night away.

For a 16-inch MacBook, the WiWU. It is the one title that says 16.2 by name, and its fingerprint lock is the one anti-theft claim here that is a part rather than a word.

For a daily commute, the Heroic Knight. Thin, expandable for the day it needs to be bigger, and sized for the laptop most people carry.

For school, the daypack that is sold to girls as well as boys. Most of this shelf says men in the first three words, and a school bag should not.

Whichever you buy, measure the laptop, ask for the litres, and buy the padlock if you actually want the word on the title to mean something.

What is good

What a title here can settle

  • The laptop it fits, on nine titles: 14, 15.6, 16.2, 17 and 17.3 inches. A laptop sleeve is a fixed pocket, and a 16-inch machine does not go in a 15.6 sleeve however the rest of the bag stretches. This is the one number to match before anything else.
  • Nine titles carry a maker's name. Tigernu, Mark Ryden, BOPAI, OZUKO, WiWU, Heroic Knight and three from HK. On a shelf where most bags are one design sold by twenty shops, a name means a size chart, a weight and a warranty address.
  • Litres, on one title, 39. Capacity is the number that says whether a bag is a day bag or a weekend bag, and one seller printed it. Twenty to thirty litres is a commute; thirty-five and up is a night away.
  • A lock in the box, on one bag with a fingerprint lock, and three padlocks sold beside them, one of them a fingerprint padlock you open with a thumb. A lock is what anti-theft actually means, and the bags that say the word mostly do not have one.
What is not great

What to read twice

  • Anti-theft means the zip is against your back. Fourteen titles say it. On a backpack it means the main zip sits against your spine where a hand in a crowd cannot reach it, and that is all it means. No title here says cut-resistant, lockable zips or a hidden pocket, which are the other things the phrase can mean and would have been worth saying.
  • A USB port is a cable through a hole. Three titles have one. It connects a power bank you bought separately, inside the bag, to a socket on the strap. It charges nothing on its own, it is a hole in a bag that says waterproof, and it is a feature to ignore rather than pay for.
  • Waterproof and water resistant are different words and the titles use both. Six say one or the other. Neither comes with a rating or a rain cover, and a backpack with a zip is water resistant at best. Assume a shower is fine and a downpour is not.
  • Not one title gives a weight. Six say lightweight. A laptop backpack weighs between 700 grams and 1.5 kilos before the laptop goes in, and the difference is a bag of sugar on your shoulder every day. Look for grams in the listing, and if there are none, assume the heavy end.
