8 Best Waterproof Backpacks for Travel, Reviewed

A 17.3-inch laptop is the reason this bag exists, and it’s the reason to skip every other pick here if you carry one. The sleeve is padded and deep enough for the big workstation machines, there’s a second spot for a tablet, and the main body is divided so cables, a power bank, and a folder of papers aren’t all sharing one hole.

We think of the KROSER as a mobile office that happens to travel. The water-repellent ballistic fabric is the most abrasion-resistant shell in this group, the RFID pocket takes cards out of the pickpocket conversation, and 45 liters means it can double as a week’s luggage if you aren’t checking a suitcase as well. The USB pass-through is the one feature that only earns its keep if you remember your own power bank and cable — the port is a wire, not a battery.

Rain is where the wording matters: the fabric repels water rather than sealing it out, which handles a wet walk from the terminal and not a soaking on an open tarmac. Keep documents and electronics in a sleeve and the difference stops mattering. The bigger issue is the shape — at 18.6 by 13.5 by 10.8 inches this is an overhead-bin companion, so budget for it in your carry-on allowance instead of assuming it slides under the seat.

Two compartments earn the coofay its place: a dedicated shoe space for a pair of sneakers or sandals, and a separate wet pocket for anything damp. On a two- or three-day trip that’s the difference between unpacking at the hotel and living out of a plastic bag, and we think it’s worth more than any charging port on this list.

The rest is sensible budget-bag design. Twenty-five liters covers a short trip’s clothes, the laptop sleeve takes a 15.6-inch machine, and the back panel is ventilated with thick multi-panel padding and adjustable straps. The shell is rated waterproof, and unlike almost everything else here it’s machine washable — a real advantage on a bag that ends a trip with a wet swimsuit in it.

What you aren’t paying for is a load-carrying harness. The padding is real but modest, and a fully stuffed 25-liter bag sits on your shoulders rather than transferring weight anywhere near your hips — fine through a terminal, noticeable on a mile-long walk to the hotel. The zippers are also where a budget bag shows its price, so pack this one full rather than overfull.

The feature list is short, and that’s the point. No ports, no cubbies, no compartments for gear you didn’t bring — just a padded 15.6-inch laptop sleeve with a separate tablet spot, seven pockets including a mesh zip pocket and pen slots, and metal double-way zippers that open without a fight. It looks like a laptop bag because it is one.

What the money goes into instead is the parts that wear out. The polyester shell is water-repellent, the stitching and zippers are the most confidence-inspiring of the budget picks here, and the air-mesh back panel with padded S-curve straps stays comfortable loaded with a laptop and two days of clothes. It’s also the plainest bag in this guide in the useful way: black, unbranded, equally at home in an office and a boarding line.

Two things to plan around. The sleeve stops at 15.6 inches, so a 17-inch workstation needs the KROSER. And this is water-resistant rather than waterproof: the coated polyester handles drizzle and a wet walk from the gate, but a real downpour works at the front pocket seams, so bag anything that has to stay dry.

At 3.7 ounces the 4Monster weighs less than the paperback in your seat pocket, and it folds into a pouch the size of a wallet that’s sewn to the bag so you can’t lose it. That’s not a travel backpack in the way the others here are — it’s the bag that lives in your suitcase until you’re somewhere worth walking around.

Unfolded it’s a real daypack: 24 liters, a main compartment, a front zip pocket, and two mesh side pockets that actually grip a bottle instead of letting it slide out. The straps are wider than most packable bags, which is why it’s comfortable for a few hours rather than a few minutes, and the water-resistant nylon handles a damp morning without soaking through.

We treat it as a second bag, and at that job it’s excellent. Thirty-denier nylon is thin by design — that’s where the weight went — so treat it as shower-proof: a day of drizzle is fine, a soaked hike isn’t. Slide it into your carry-on and a beach day, a market, or a trailhead stops being something you plan around your good bag.

Twenty-five liters is a number that lies in both directions. Pack thin clothes to the zipper stops and it’s a week; pack like a normal person and it’s three days. The coowoz sits firmly in the second camp, so plan on a few days of clothes and a laptop rather than a full vacation wardrobe.

What it does better than most is separate the mess. The wet bag is high-density water-resistant material with its own space, the shoe compartment takes a pair of sneakers, and the body splits into two main pockets with a 15.6-inch laptop sleeve between them. Seven pockets in a bag this size is a lot of places to lose a passport — and a lot of places to put one.

At 1.7 pounds it’s the lightest of the structured packs here, and its padding is the more forgiving of the two cheap 25-liter bags on this list; we noticed the difference at the end of a long airport day rather than at the start of one. The side pockets are snug, though: a wide-mouth bottle rides high, so bring a slim one or clip your bottle to the outside.

One more thing we appreciated: the olive green hides airport grime in a way the pale colorways don’t, which matters on a bag that spends its life on floors and under seats.

Everything else on this list is 24 liters or more; the Capolo is 20, and that’s the point. At 16.5 by 11.5 by 7 inches it’s the shape a gate agent’s personal-item frame is built for, so it’s the one to take when the ticket says one small item and nothing else — and the one least likely to be weighed or eyeballed.

Eleven pockets is a lot for 20 liters, and most of them earn their place: a padded 15.6-inch laptop sleeve, a zippered mesh section, and enough small compartments that you stop digging for a charger mid-security-line. The main compartment opens 180 degrees like a suitcase, which is what makes a bag this small livable for a few days.

Four side compression buckles are the detail we didn’t expect to care about. Cinched down on a half-empty pack they stop it sagging into a sack, and the side handle lets you carry it like a tote through a crowd instead of on one shoulder the whole way.

It lands as an also-consider rather than a top pick because of what 20 liters asks of you: no spare shoes, one sweater, and laundry on anything longer than a long weekend. Pack it for three days and it’s superb; pack it for a week and you’ll be rinsing things in a sink.

It’s the least expensive bag here and, at about a pound, the lightest of the full-size packs — two facts that explain most of what follows. The shell is water-resistant polyester, the body measures 16.5 by 12.6 by 7 inches, and 24 liters holds a few days of clothes as long as you’re not also packing for a hike.

Two independent main compartments are the detail that stands out. A large one for clothes and a slim one for books or a tablet means you aren’t excavating a single hole every time you want a layer, and the front quick-access pocket plus two mesh side pockets cover the small stuff. Six pockets in a bag this plain is more organization than the price suggests.

Where the value shows through is in upkeep: the polyester sheds light rain and spills, and unlike most picks here it can go in the washing machine — a genuine advantage after a summer of bus seats and airport floors.

The savings show up in the hardware. The side mesh and the zipper pulls are the parts to watch, particularly if you pack it heavy, so treat this as a light-load travel pack for short trips and let it do the job it’s priced to do.
