Best Waterproof Backpack With Laptop Compartment: 5 Top Picks Compared

A waterproof backpack with a laptop compartment can help protect your computer during commutes, travel, and rainy-day errands—but “waterproof” can mean different things. Some bags use water-resistant fabric rather than a fully sealed construction, so it’s worth checking the materials, zippers, and laptop fit before you buy. These five options range from slim business bags to highly organized everyday packs, with different levels of storage and weather protection.

Our Picks: Best Waterproof Backpack With Laptop Compartment reviews

1. BANGE Business Smart Backpack: Best for Easy Laptop Access

This BANGE backpack is a business and travel option made with high-density coated Oxford fabric, which the product information describes as waterproof and scratch-resistant. Its laptop compartment opens 180 degrees, giving you broad access to the computer section when packing or taking out a device.

The bag measures 12.2 by 18.9 by 5.5 inches and weighs 2.65 pounds. It has five pockets, including two front pockets and a main compartment described as roomy enough for several changes of clothes. The shoulder straps add a card pocket and a glasses hook, small details that may be useful when you want frequently used items close at hand.

There is a laptop-size detail to check before ordering: the dedicated compartment is described as fitting a 15.6-inch laptop, while the listing also mentions 17-inch accommodation. If your device is larger, compare its dimensions with the bag’s internal measurements or confirm fit with the seller. This is also one of the heavier options here, so it may feel less appealing if you prioritize a very light daily bag.

Pros:

• Coated Oxford fabric is described as waterproof and scratch-resistant.
• 180-degree laptop compartment makes access straightforward.
• YKK zippers and useful strap details add convenience.
• Room for clothing and travel essentials as well as a laptop.

Cons:

• At 2.65 pounds, it is heavier than several alternatives here.
• The laptop-size details are not fully consistent, so larger-device owners should verify fit.

Verdict: Choose this BANGE if you want a travel-ready business backpack with a wide-opening laptop section and coated fabric, but confirm your computer’s fit before buying.

2. BANGE Anti-Theft Backpack: Best for a Larger Laptop and Lockable Storage

This BANGE model is designed for commuters and business travelers who want more security features than a basic laptop bag provides. Its separate laptop compartment is listed for computers up to 17.3 inches, and the middle pocket includes a combination lock made from zinc alloy. The lock is intended to help secure valuables, though it should not be treated as a guarantee against theft.

The bag has three main separated pockets. The front section can hold shoes or smaller personal items, while the main storage areas help keep work gear apart from other belongings. Water-resistant Oxford fabric and a waterproof YKK zipper are listed as part of its weather protection. It also has an external USB 3.0 charging port; you’ll need a compatible power source inside the bag to use it.

Breathable mesh on the back and shoulder straps may make the pack more comfortable for longer walks, and the top handle offers another way to carry it. Compared with the first BANGE option, this one supports a larger stated laptop size and adds a lock, but it does not list the same 180-degree-opening compartment. The security features and larger-device capacity may also be more than you need for a simple, lightweight commute.

Pros:

• Dedicated laptop compartment is listed for devices up to 17.3 inches.
• Combination lock adds a layer of security for the middle compartment.
• Water-resistant fabric is paired with a waterproof YKK zipper.
• USB 3.0 port and breathable back and straps support travel use.

Cons:

• The USB port requires a separate power source.
• A lock can deter casual access but cannot ensure valuables are theft-proof.

Verdict: This is a strong fit if you carry a larger laptop and value lockable storage, especially for business trips and commuting.

3. LOVEVOOK Laptop Backpack: Best for Everyday Organization

The LOVEVOOK backpack pairs a separate padded laptop compartment with a more casual, organized layout. It is listed with four compartments and 14 pockets for items such as a computer, tablet, folders, bottles, umbrella, and work or school supplies. The dedicated sleeve fits a 15.6-inch laptop, and a separate slot is listed for a 9.7-inch tablet.

A standout feature is the adjustable elastic pouch designed for a large-capacity cup. The pack also includes a back anti-theft pocket and a luggage strap for sliding over a suitcase handle. At 1.85 pounds, it is lighter than the first BANGE option, while its 12-by-17.5-by-8-inch size gives it a deeper profile than the slim business packs.

The fabric is described as water-resistant polyester, not fully waterproof construction. That makes it a practical choice for everyday use and light exposure to rain, but it is not the best match if you need a bag for prolonged downpours or wet outdoor conditions. The colorful, fashion-focused design may also be less suited to shoppers who want a plain, formal business look.

Pros:

• Numerous pockets help separate work, school, and travel items.
• Padded 15.6-inch laptop compartment and separate tablet slot.
• Large-cup pouch, anti-theft back pocket, and luggage strap add useful touches.
• Listed weight is 1.85 pounds.

Cons:

• Water-resistant fabric is not the same as a fully waterproof bag.
• The deeper shape may feel bulky if you prefer a slim profile.

Verdict: Pick the LOVEVOOK if organization, a dedicated cup pouch, and travel-friendly features matter more to you than a fully waterproof build.

4. hk Slim & Expandable Backpack: Best for Flexible Packing

This hk backpack is built around a useful trade-off: it stays slim for daily use but expands when you need more packing room. The listing says capacity can increase from 15 liters to 27 liters by opening the expansion zippers. It is designed for laptops up to 17 inches and measures 12.6 by 3.15 by 18.9 inches before expansion.

At 1.65 pounds, it is the lightest option in this comparison with a stated weight. Other practical features include a USB charging port with an interior cable, a hidden back zip pocket, padded straps and back panel, and a luggage strap. The USB port requires a power bank, which is not included.

The product title calls out 900D material, while the description identifies the fabric as water-resistant Oxford material. That is useful protection for everyday conditions, but the supplied details do not establish that the bag is sealed against heavy rain or submersion. Its narrow 3.15-inch depth in the slim configuration may also limit how much you can pack until you expand it.

Pros:

• Expands from 15L to 27L for changing travel and commute needs.
• Fits laptops up to 17 inches according to the listing.
• Light listed weight of 1.65 pounds and a luggage strap.
• Hidden back pocket and USB port add everyday convenience.

Cons:

• Water protection is described as water-resistant, not fully waterproof.
• The USB port needs a separate power bank.

Verdict: Choose this hk pack if you want a light, slim commuter bag that can expand for a weekend trip or a heavier workday load.

5. Maelstrom 15.6-Inch Laptop Backpack: Best for a Neat Business Setup

The Maelstrom is a compact business backpack with a dedicated 15.6-inch laptop sleeve and a structured opening intended to make it easier to reach the computer compartment. Its listed dimensions are 12.6 by 3.54 by 16.54 inches, making it a relatively slim choice for daily commuting or work travel.

Inside, the layout includes a main compartment, a padded laptop sleeve, a tablet slot, two mesh pockets, a zippered pouch, two quick-access front pockets, and a front organizer. A USB charging port with an interior cable is included in the design, but the power bank is not included. For travel, it has a luggage strap, while EVA foam padding on the back and shoulder straps is intended to improve airflow and comfort.

The fabric is described as high-density composite coated and water-resistant. That should help with everyday splashes and light rain, but the description does not promise a sealed bag for heavy rain or immersion. Its laptop capacity is also smaller than the two BANGE models and the expandable hk pack, so it is not the best pick for a 17-inch computer.

Pros:

• Dedicated 15.6-inch laptop sleeve and separate tablet slot.
• Structured opening and several organizer pockets keep work items accessible.
• Luggage strap and breathable padded back and shoulder straps support travel use.
• Coated fabric is described as water-resistant and easy to wipe clean.

Cons:

• Not intended for laptops larger than the listed 15.6-inch size.
• The USB port needs a separate power bank, and the fabric is not described as fully waterproof.

Verdict: The Maelstrom is a sensible option for a tidy business commute with a 15.6-inch laptop, especially if you value a structured interior over expandable capacity.

How to Choose a Waterproof Backpack With a Laptop Compartment

Check the Laptop Compartment Dimensions

A laptop-size label is a useful starting point, but screen size alone does not tell you whether your computer will fit. Compare your device’s full width, height, and thickness with the bag’s compartment dimensions when those measurements are available. This is especially important for the first BANGE backpack, whose description gives different laptop-size details. Leave room for a protective case if you plan to use one.

Understand What “Waterproof” Means

Fabric described as water-resistant can help protect your belongings from splashes and light rain, but it does not guarantee protection in a prolonged downpour. Check whether the product information specifies coated fabric, waterproof zippers, or other weather-resistant details. Among these choices, the first BANGE listing describes its coated Oxford fabric as waterproof, while the LOVEVOOK, hk, and Maelstrom descriptions use water-resistant language. For valuable electronics, a separate sleeve or dry bag can provide an extra layer of protection.

Match Capacity to Your Routine

Think about what you carry besides your computer. A slim commuter bag may be easier to manage on a crowded train, while a deeper bag or an expandable design can make room for clothes, a lunch container, or extra work gear. The hk backpack expands from 15L to 27L, while the LOVEVOOK offers many pockets and a cup pouch. The BANGE business model has space for travel clothing, according to its description.

Consider Organization and Access

Separate laptop and tablet sleeves can help keep devices from rubbing against other items. Front pockets are handy for items you reach for often, while a wide-opening compartment can make packing easier. The first BANGE model has a laptop section that opens 180 degrees; the Maelstrom lists a structured opening and a range of organizer pockets. Choose a layout that suits what you carry rather than focusing only on the number of pockets.

Look at Carry Comfort and Travel Features

Padded straps and a breathable back panel can matter when you carry a loaded bag for a long commute or through an airport. If you travel with rolling luggage, a luggage strap can make the backpack easier to manage. The LOVEVOOK, hk, and Maelstrom include luggage straps in their descriptions. Consider the bag’s own weight as well: the listed weights vary, from 1.65 pounds for the hk backpack to 2.65 pounds for the first BANGE model.

Decide Whether USB Charging or a Lock Is Useful

An external USB port lets you connect a power source inside the bag to a device outside, but it is not itself a battery. Check whether a power bank is included; the hk and Maelstrom descriptions specify that it is not. If you want a lockable compartment, the second BANGE has a combination lock. These features can be useful, but they should not take priority over laptop fit, comfort, and the level of weather protection you need.

Frequently Asked Questions

Are these backpacks fully waterproof?

Not all of them. Several are described as water-resistant, which is different from a fully sealed waterproof bag. The first BANGE listing describes its coated Oxford fabric as waterproof, and the second BANGE lists water-resistant fabric with a waterproof zipper. For heavy rain or water exposure, check the product details carefully and consider an additional protective sleeve for your laptop.

Which backpack fits the largest laptop?

The BANGE Anti-Theft Backpack is listed for laptops up to 17.3 inches. The hk backpack is listed for up to 17 inches. Check your computer’s actual dimensions before ordering, since devices with the same screen size can have different overall measurements.

Do the USB charging ports include a power bank?

The USB ports are designed to connect to a power source inside the bag. The hk and Maelstrom listings state that the power bank is not included. Check each product’s current package details before buying if a power bank is important to you.

Which option is best for a 15.6-inch laptop and lots of small items?

The LOVEVOOK is listed with a 15.6-inch laptop pocket and 14 pockets, making it a good match if you want extensive organization. The Maelstrom also fits a 15.6-inch laptop and offers a work-focused arrangement with several dedicated storage sections.

Which backpack is the lightest?

Among the products with a listed weight, the hk backpack is the lightest at 1.65 pounds. The LOVEVOOK is listed at 1.85 pounds, while the first BANGE model is listed at 2.65 pounds. The other product descriptions do not provide a weight.

Can I use these backpacks for air travel?

The product descriptions position several of these bags for travel, and the LOVEVOOK, hk, and Maelstrom include luggage straps. Whether a backpack works as a personal item depends on the airline and your packed bag’s final dimensions, so check your carrier’s size rules before traveling.

Final Recommendation

For a balance of laptop access and coated fabric described as waterproof, the BANGE Business Smart Backpack is a strong starting point—just confirm your computer’s fit because its size details are inconsistent. Choose the BANGE Anti-Theft model if you need space for a larger laptop and want a lockable compartment. For an expandable, lightweight commuter pack, the hk is the most flexible option; for abundant organization, consider LOVEVOOK or Maelstrom. In every case, match the laptop compartment to your device and treat water-resistant fabric as protection for everyday conditions, not a promise of submersion safety.
