HP 15.6-inch Modular Laptop Backpack — Three Bags in One, 27 L
Backpack + Sleeve + Pouch27 L · 1540 g51% Post-Consumer RecycledRFID Pocket + Rain Cover
HP describes the 15.6-inch Modular Laptop Backpack as three products in one, and that is literal: a 27 litre backpack, a detachable laptop sleeve and a removable pouch, with removable straps so the sleeve or the pouch can be carried on their own or together. Use the whole thing for a full day, or take out just the sleeve when you want to travel light. It is made from water-resistant twill polyester containing 51% post-consumer recycled plastic — the equivalent of 61 plastic bottles — in grey and green. The padded laptop compartment takes machines up to 15.6 inches, there is a dedicated RFID-blocking pocket, the zips are lockable with cable pass-throughs, and a water-resistant rain cover is included. It measures 325 x 200 x 495 mm and weighs 1540 g. HP covers it with a three-year limited warranty.
Compatibility — check before buying:
This is a backpack, and HP calls it one. Our previous listing described it as a “notebook carrying case”, which understates it considerably — HP’s own product name is the 15.6-inch Modular Laptop Backpack.
Make sure you receive all three parts. The box contains the backpack, a detachable laptop sleeve, a removable pouch and removable straps. Buyers who are not told this sometimes report the sleeve and pouch as “missing parts” when in fact they are the product. If anything is absent when your order arrives, tell us.
Colour is grey and green. HP’s datasheet states Gray and Green, and that is correct despite some listings recording it as black — an artefact of how HP’s regional product imagery is scraped.
Laptop fit: HP states the compartment fits most laptops up to 15.6 inches diagonal. HP publishes no internal compartment dimensions, no padding thickness and no individual dimensions for the sleeve or the pouch, so if your machine is unusually thick or large for its class, ask us before ordering.
What HP does not claim: there is no tablet compartment and no water bottle pocket published for this backpack, and no water-resistance rating or test standard — only “water-resistant twill polyester” plus the included rain cover. Note also that HP publishes no QuickSpecs document for this accessory; the product datasheet is the authoritative source and that is what we have used.
Best For
✓ Anyone who wants one bag for the commute and a slim sleeve for the meeting, without buying two
✓ Daily carry of a 15.6 inch laptop plus a charger, documents and a change of clothes in 27 litres
✓ Travellers — the trolley pass-through, lockable zips and included rain cover are all built for it
✓ Buyers with recycled-content procurement criteria: 51% post-consumer recycled plastic, published by HP
✓ Anyone carrying contactless cards or a passport, with a dedicated RFID-blocking pocket
Key Features
Three products in one
HP’s own wording: use the full laptop backpack, or separate the sleeve and the included pouch when you want to travel light. The pouch is described as a secure, detachable compartment for a wallet, passport and tickets, and the removable strap lets you carry the sleeve or the pouch separately or together. In practice this replaces a backpack plus a slim laptop bag plus a travel wallet.
51% post-consumer recycled plastic
HP publishes the figure as a percentage and as an equivalent — 61 plastic bottles per bag. Unlike many recycled claims, this is stated at product level rather than for the shell fabric alone, and the external fabric and interior lining are both specified as 100% polyester with PE foam padding.
A dedicated RFID-blocking pocket
HP’s wording is explicit: protect credit cards and other sensitive information with a dedicated RFID-blocking pocket. Increasingly relevant now that cards, passports and building passes are all contactless.
Lockable zips with cable pass-throughs
The zips take a lock, and the cable pass-throughs mean headphones or a charging cable can run out of a closed compartment. Small detail, meaningful on a bag left in a hotel room or a shared office.
27 litres and a trolley pass-through
Enough for a 15.6 inch laptop, its charger, documents and an overnight change. The pass-through slides the bag over rolling luggage, so a loaded 1540 g pack is not on your shoulders through an airport.
Rain cover included
HP supplies a dedicated water-resistant rain cover with the bag rather than selling it separately, alongside the water-resistant twill polyester shell. Most manufacturers charge extra for this.

Frequently Asked Questions
What does “modular” mean here?
It is literal. HP’s own words are “three products in one”: you can use the full backpack, or separate the laptop sleeve and the included pouch when you want to travel light. Removable straps let you carry the sleeve or the pouch on their own or together.
What is in the box?
The backpack, a detachable laptop sleeve, a removable pouch and removable straps. Because listings often omit the sleeve and pouch, some buyers assume parts are missing when they are not — they are the product.
What colour is it?
Grey and green, per HP’s datasheet. Some listings record it as black; that comes from how HP’s regional imagery is scraped rather than from HP’s own specification.
Is there a tablet compartment?
Not one HP publishes. There is a padded laptop compartment for machines up to 15.6 inches, and the modular sleeve, but no separate tablet pocket appears in HP’s specification.
Is it waterproof?
No. HP describes the fabric as water-resistant twill polyester and includes a water-resistant rain cover, but publishes no rating or test standard. The rain cover is the thing to use in real rain.
How recycled is it?
HP publishes 51% post-consumer recycled plastic, equivalent to 61 plastic bottles. That is a product-level figure rather than a shell-only claim, which makes it more meaningful than most.
What warranty applies?
HP publishes a three-year limited warranty for this backpack, which is longer than the one year HP typically gives accessories. Our store warranty is one year, and both sit alongside your statutory rights.
Singular Expert Insight
Most “modular” bags are a marketing word applied to a removable pocket. This one is not: HP ships a backpack, a detachable laptop sleeve, a removable pouch and removable straps, and describes it in its own copy as three products in one. That matters in a specific situation — you commute in with everything, then walk into a meeting or a client office carrying just the sleeve with the machine in it. The alternative is owning two bags and remembering to transfer things between them.
The pouch is a smaller idea but a good one. HP positions it for wallet, passport and tickets, and it detaches with its own strap. Anyone who travels knows the awkwardness of the documents you need at four different points in a journey living in the bag you have just put in an overhead locker.
On sustainability, HP does something most bag makers avoid: it publishes a product-level figure. Fifty-one per cent post-consumer recycled plastic, equivalent to 61 bottles. Compare that with the common approach of claiming 100% recycled fabric while quietly lining the bag with virgin polyester. If you are buying against a procurement criterion, 51% is a number you can put in a tender and defend.
The security and travel details are unusually complete for the price. A genuinely dedicated RFID-blocking pocket rather than a vague claim. Lockable zips with cable pass-throughs, so a charging cable can run out of a closed compartment. A trolley pass-through. And a rain cover in the box rather than sold separately, which is a small cost to HP and a real convenience to you.
Two limitations to know. HP publishes no tablet compartment and no water bottle pocket for this bag, and it publishes no internal dimensions, no padding thickness and no individual sizes for the sleeve or the pouch. So if your laptop is thick or large for a 15.6 inch class machine, the honest answer is that HP’s data does not let anyone tell you definitively whether it will fit — ask us and we will check with the distributor rather than guess. There is also no QuickSpecs document for this accessory, which is normal for this product class; the datasheet is the authoritative source and it is what we have used here.
The three-year limited warranty is worth noting. HP’s usual accessory term is one year, so this is an explicit exception and a reasonable signal about expected life.
Buyer’s Guide
Buy it if
Buy the HP 15.6-inch Modular Laptop Backpack if you want one purchase to cover a commuting backpack, a slim laptop sleeve for meetings and a travel pouch for documents. Check that your laptop is comfortably within 15.6 inches, and be aware there is no published tablet compartment or bottle pocket. Expect grey and green rather than black, and make sure all three parts are in the box when it arrives.
Skip it if
You need a laptop larger than 15.6 inches, a dedicated tablet compartment or a water bottle pocket — HP publishes none of these. Also skip it if you want a plain black bag; this one is grey and green and HP does not publish an alternative colour under this part number.
Also consider
