A rain shower on the walk to the office is enough to turn an unprotected laptop bag into a ruined laptop. People who search for the best waterproof laptop backpacks usually have a specific route in mind: a bike commute, a long bus stop, a campus with no covered paths, or a flight where the bag sits on a wet tarmac. The decision comes down to how much weather protection the fabric and zippers claim, and how well the bag fits the laptop you actually carry.
This guide is for students, commuters, and travelers who want a padded home for a 15.6 or 17 inch laptop. A key point before you read on: the listings use two different phrases. Four say waterproof, and five say water resistant, which usually means light rain and splash protection rather than total sealing. One backpack in the brief, from The North Face, was left out because its title makes no water claim at all. Judged only on listing titles, the nine below are the ones that fit the 2026 commuter brief.

How to Choose
Know the difference between waterproof and water resistant
Water resistant fabric sheds light rain and splashes. A bag marketed as waterproof is claiming more, but zippers, seams, and the bottom panel are usually the weak points. If your commute is a long walk or a bike ride, look for a listing that names waterproof construction and pack electronics inside a sleeve anyway. Look at the bottom of the bag too, since a bag set down in a puddle takes water from below rather than above.
Match the laptop size
The titles here cover 15.6, 17, and 17.3 inch laptops. Check your laptop’s width and thickness, not only its screen size, since gaming laptops are often bulkier than the label suggests. A 17 inch bag holds a 15.6 inch laptop with room to spare, but a 15.6 inch bag will not take a 17 inch one.
Weigh the extras that matter
USB charging ports on the outside connect to a power bank you supply, so they help only if you carry one. Count the compartments as well: a separate pocket for a charger and mouse keeps cables from pressing against the screen. Anti-theft pockets, luggage straps, and padded sleeves protect against theft and bumps. For flying, personal-item size or 20L capacity makes the bag easier to slide under a seat.
Where budget bags cut corners
Thin padding, light zippers, and straps with little shaping are common at the low end. Heavier fabric, usually stated as a denier number such as 900D, tends to resist abrasion. Ignore vague marketing words like durable, and look for stated capacity and laptop size.
The 9 Best Options
DUSLANG 17 inch
A travel backpack for laptops up to 17 inches that is described as water resistant, with a protective pad, a business daypack look, and an anti-theft design. It is the water-resistant choice for someone who carries a big laptop and wants a conservative, office-friendly shape.
- Strength: the 17 inch size covers large laptops.
- Strength: protective padding and anti-theft details are listed.
- Trade-off: water resistant is a lighter claim than waterproof.
Skip it if your commute involves heavy rain or you need a stated waterproof claim on the listing. A student who mostly walks between covered buildings, though, will find the padding and the oversized compartment more than adequate.
BANGE Business Smart
This business backpack is labeled waterproof and fits a 15.6 inch laptop. The listing mentions a USB charging port but also shows a no USB variant in a large size, so confirm which version you are ordering.
- Strength: waterproof wording in the title.
- Strength: a business style that works for travel and the office.
- Trade-off: the title is ambiguous about the USB port, so check the variant.
Skip it if you carry a 17 inch laptop or need a clear, single configuration. Buyers who like a simple listing may prefer a bag whose title does not carry two versions at once.
hk Business Backpack
A slim, expandable backpack for a 17 inch laptop, stated as 900D waterproof, with a USB charger, anti-theft features, and a lightweight, large computer bag design. The expandable body adds room when a trip calls for extra clothing.
- Strength: 900D waterproof fabric is the most specific durability claim in the list.
- Strength: expandable design adds flexibility for travel.
- Trade-off: the title does not state a capacity in liters.
Skip it if you want a minimalist bag with no expansion zipper. An expandable body can also invite overpacking, which strains straps and seams over time.
MATEIN Travel 15.6 inch
A grey 15.6 inch laptop backpack aimed at college and travel, described as slim, sturdy, anti-theft, and water resistant. The title also lists personal item bag use, which suggests it is meant to fit under an airline seat.
- Strength: personal item sizing is useful for flights.
- Strength: a slim profile suits tight spaces.
- Trade-off: water resistant, not waterproof.
Skip it if you need to protect a laptop in heavy rain or carry more than a day of gear. A slim shape trades capacity for a tidy fit, so a long trip with a change of clothes may call for something roomier.
Volher Slim
A black 15.6 inch business and travel backpack that is slim, anti-theft, water resistant, and described as durable. The title is short on specifics, so it reads as a straightforward everyday bag.
- Strength: the slim anti-theft design keeps it low-profile.
- Strength: it fits a 15.6 inch laptop and notebook.
- Trade-off: no capacity, padding detail, or USB port is listed.
Skip it if you need a big laptop, a charging port, or stated waterproofing. It suits a light, dry commute where the bag is mostly a tidy way to carry a laptop, a charger, and a notebook.
MATEIN Business
A black 15.6 inch laptop backpack for work and college, listed as water resistant, with a personal item size, an anti-theft pocket, and a luggage strap. The luggage strap slides over a rolling suitcase handle, which helps with airport days.
- Strength: the luggage strap simplifies travel.
- Strength: an anti-theft pocket protects valuables.
- Trade-off: water resistant only.
Skip it if you want a USB port or true waterproof claims. The strap and the pocket are the selling points, so it works best for people who ride trains more than they walk in the rain.
SUIKIHUM 20L
A 20L backpack for 15.6 inch laptops, labeled anti-theft, flight approved, and water resistant, with a padded laptop sleeve and organized storage. It is one of the few titles to state a capacity.
- Strength: the 20L figure makes packing easier to judge.
- Strength: a padded laptop sleeve is listed.
- Trade-off: water resistant rather than waterproof.
Skip it if you need a 17 inch laptop compartment. A traveler who also wants to carry a jacket and shoes may find 20L tight, so think about your usual load.
LOVEVOOK for Women
A women’s laptop backpack in beige, black, and brown, labeled waterproof, with a pouch pocket for a large cup, 15.6 inch laptop support, and a purse-like look for teachers and office workers.
- Strength: waterproof wording and a dedicated cup pocket.
- Strength: a styled look that suits professional settings.
- Trade-off: the title does not state a capacity or padding detail.
Skip it if you prefer a plain tech look or need space for a 17 inch laptop. The cup pocket is a convenience for commuters who carry a drink, though it will not help if you want a bag that disappears into a crowd.
MARK RYDEN 17.3 inch
A business backpack for 17.3 inch laptops, labeled waterproof, with a USB charging port, and positioned for travel, office, college, commuting, and hiking.
- Strength: it carries the largest laptop size in the list.
- Strength: waterproof wording and a USB port.
- Trade-off: the title gives no capacity figure.
Skip it if you carry a small laptop and want a slimmer bag. A 17.3 inch compartment is generous, and it can feel oversized on a petite frame or a short commute.
Which One Fits Your Situation
You commute in the rain
Take the hk Business Backpack or the MARK RYDEN, since both are labeled waterproof and fit large laptops. The BANGE is also labeled waterproof for a 15.6 inch laptop. Whichever you choose, keep the laptop in an inner sleeve, because a waterproof outer shell does not protect an open zipper in a downpour.
You fly often
The SUIKIHUM 20L and the MATEIN Business bag both mention flight or personal-item sizing, and the MATEIN adds a luggage strap. Measure the airline’s under-seat limits first, because the titles describe sizing without giving the exact dimensions.
You carry a 17 inch laptop
The DUSLANG, hk, and MARK RYDEN all state 17 inch or larger support. The MARK RYDEN goes up to 17.3 inches, so it is the one to check first if your laptop is a chunky gaming model. Compare the listed size with the dimensions printed on your laptop’s spec sheet.
You want a professional look
The LOVEVOOK has a styled design with a cup pocket, while the Volher keeps a slim, understated profile. Anyone who wants a quiet design with a stated weather claim can also look at the MATEIN Travel, which pairs a slim shape with water resistant fabric.
Common Mistakes
- Treating water resistant as the same as waterproof.
- Ordering by screen size without checking the laptop’s thickness.
- Assuming a USB port includes a battery.
- Skipping a rain cover when the zippers are the weak point.
- Overloading a slim bag and straining the seams.

Frequently Asked Questions
Does waterproof mean it can be submerged?
Not necessarily. Most backpack listings use the word for rain protection, and zippers and seams limit how much water the bag can take.
Can a 15.6 inch bag hold a 17 inch laptop?
Generally no. Pick a bag that names the larger size, and compare the interior width with the laptop’s width rather than relying on the screen number alone.
Is a USB port useful?
It passes power from a power bank you place inside. It does not charge by itself.
How can I keep my laptop dry in any bag?
Put it in a padded sleeve and avoid setting the bag on wet ground. A rain cover adds another layer, and a zip bag inside the backpack gives a last line of defense for chargers and papers.
