Our Picks: Best Leather Attache Case With Shoulder Strap reviews
1. Masa Kawa Large Black Leather Briefcase: Best for a 17-Inch Laptop
This is the roomiest option in the group, with a padded sleeve designed for a 17-inch laptop and a large main compartment. The bag measures 17.7 by 3.9 by 12.6 inches and weighs 3.3 pounds, so it offers plenty of space but is not a lightweight pick.
Its full-grain calfskin exterior is paired with a broad set of storage options: front magnetic pockets, a front zip pocket with a tablet sleeve, card and pen slots, interior pouches, and a separate back compartment. A back zip pocket converts into a luggage sleeve when you open its zippers. The adjustable strap is listed at 35.4 to 59.8 inches, giving you room to set a comfortable carry length.
The layout makes sense if you bring a large computer, documents, and smaller work items and want them separated. For a slimmer daily load, though, this case may feel bigger than necessary. Its larger size and stated weight are worth considering if you expect to carry it for long stretches.
Pros:
- Padded sleeve for a 17-inch laptop
- Many pockets and organizers for work essentials
- Adjustable shoulder strap and top handles
- Back pocket converts into a luggage sleeve
Cons:
- At 3.3 pounds, it is heavier than the slim 14-inch option
- Its large format may be more bag than a light commuter needs
Verdict: Choose this briefcase if your priority is carrying a large laptop and a well-organized load, and you are comfortable with a larger, heavier case.
2. Masa Kawa Vintage Full-Grain Briefcase: Best for Two Devices
This medium-size briefcase is made from 2 mm thick full-grain leather treated for a weathered, vintage look. The maker describes the finish as one that develops a shinier appearance with use. Its dimensions are 15.8 by 10.8 by 4.1 inches, and it weighs 3.6 pounds.
Its main distinction is the two laptop sleeves: one fastened sleeve and one detachable sleeve, with the bag described as fitting most 15.6-inch laptops. The compartments also include pouches, card slots, and a zip pocket. A front flap pocket, adjustable and detachable shoulder strap, and luggage strap add useful options for work and travel.
This is a flexible layout for someone who carries a laptop alongside a tablet or another device. The trade-off is weight: at 3.6 pounds, it is the heaviest option listed here. The two-sleeve setup may also be unnecessary if you carry only one computer and prefer a simpler, lighter case.
Pros:
- Two sleeves for carrying a laptop and another device
- Adjustable, detachable shoulder strap
- Luggage strap for use with a rolling suitcase
- Full-grain leather with a distinctive vintage finish
Cons:
- Heaviest of the five listed options at 3.6 pounds
- May have more capacity and organization than a one-device commuter needs
Verdict: Pick this model if carrying two devices and keeping accessories sorted matter more than minimizing the bag’s weight.
3. Masa Kawa Slim Brown Briefcase: Best for a 14-Inch Laptop
At 2.2 inches thick and 2.6 pounds, this brown briefcase is the slimmest and lightest of the five options listed. It is made from full-grain leather and sized at 15 by 2.2 by 10.6 inches, with a padded compartment for a 14-inch laptop.
The main compartment opens flat, a design intended to make access easier at airport screening. Inside, the bag has mesh pouches, additional pockets, and pen slots; a front zip pocket and a back pocket provide more places for small items. Its adjustable strap has a wide shoulder pad and can also be detached when you want to carry the case by its handles.
This design suits a compact laptop and a tidy daily load better than bulky folders or several large accessories. Its slimmer profile is convenient for commuting, but the listed 14-inch laptop fit is smaller than the capacity of the other models. Check your computer’s actual width and depth against the bag before buying.
Pros:
- Lightest option listed, at 2.6 pounds
- Slim 2.2-inch profile
- Detachable strap with a wide shoulder pad
- Flat-opening compartment and organized pockets
Cons:
- Designed for a 14-inch laptop rather than larger computers
- Limited depth may not suit a bulky daily load
Verdict: This is the best fit for a compact laptop and a lighter commute, especially if you want the option to remove the shoulder strap.
4. Masa Kawa Slim Black Briefcase: Best for a Formal, Travel-Ready Look
This black leather briefcase has a slim 1.9-inch profile and measures 16.3 by 11.4 inches. It weighs 3.42 pounds and is designed for most 15.6-inch or 16-inch laptops. The padded sleeve has elastic belts to help hold a computer in place.
The maker describes the cowhide as offering water resistance against light rain, not as a fully waterproof case. The bag also has a lay-flat main compartment, a removable adjustable shoulder strap, and a back luggage belt for attaching it to a rolling suitcase. Its organizer layout is intended for items such as cards, pens, cables, a phone, and a passport.
The narrow profile is a good match for business meetings and commutes when you want a streamlined shape, and the luggage belt is useful for trips. The listed weight is worth factoring in, particularly if you usually carry the case by hand. As with any slim bag, it may be less suitable if you regularly bring bulky accessories.
Pros:
- Slim profile for a case designed around a 15.6- or 16-inch laptop
- Removable, adjustable shoulder strap
- Luggage belt for rolling-suitcase travel
- Lay-flat main compartment and multiple organizer spaces
Cons:
- At 3.42 pounds, it is not the lightest slim case
- Water resistance is described for light rain, not full submersion or heavy exposure
Verdict: Choose this black model if you want a slim business style with a laptop sleeve and travel features, while keeping its weight and limited depth in mind.
5. Masa Kawa Slim Vintage Brown Briefcase: Best for Cushioned Laptop Storage
This slim vintage-brown case is designed to fit most 16-inch laptops. Its laptop compartment has three cushioning layers with 4 mm of padding and a soft velvet lining, with the aim of helping protect a computer’s edges and screen from bumps. The maker describes the 1.8 mm full-grain leather as developing a patina with use.
The bag includes a detachable, adjustable shoulder strap and a luggage sleeve. For smaller items, its pockets and organizers include card slots, pen loops, a key hook, and several pouches. A separate back zip pocket sits beneath the luggage strap, and the case has magnetic-snap pockets for notebooks.
This model focuses on laptop cushioning and a slim shape rather than a large, open interior. Its listed availability is currently unavailable in the supplied product information, so confirm that the listing can be ordered before making it your choice. The product information does not provide dimensions or weight, making it harder to compare its fit and carry feel with the other options.
Pros:
- Three-layer, 4 mm cushioned laptop compartment
- Designed for most 16-inch laptops
- Detachable shoulder strap and luggage sleeve
- Multiple pockets for small work and travel items
Cons:
- Supplied availability information lists it as unavailable
- Dimensions and weight are not provided in the supplied details
Verdict: Consider this case if laptop cushioning and a slim vintage-brown style are your priorities, but verify availability and fit details before choosing it.
How to Choose a Leather Attache Case With a Shoulder Strap
Match the laptop sleeve to your device
Start with your laptop’s actual measurements, not only the screen size in its name. Laptop bodies can vary, and a snug sleeve may not fit a computer with a thick case or protective cover. The listed options range from a 14-inch sleeve to models designed for 17-inch laptops, so compare the bag’s stated capacity with your device before ordering.
Think about what else you carry
A laptop is only part of your daily load. Consider whether you also bring a tablet, charger, notebook, files, pens, keys, or travel documents. The large black briefcase offers a broad selection of pockets, while the vintage full-grain model stands out for having two laptop sleeves. A slimmer case may be easier to carry when your everyday essentials are limited.
Check the strap and carry options
An adjustable strap helps you set the bag to your preferred shoulder or crossbody length. A detachable strap can be useful when you want to carry the case by its handles or remove the strap for a more formal look. If you travel with a rolling suitcase, look for a luggage sleeve or belt, and confirm how it is designed to work.
Balance capacity with weight and thickness
A larger case can hold more but may feel bulky during a long commute. The listed weights range from 2.6 to 3.6 pounds, before you add a laptop and other gear. Thickness also varies: the slim models are suited to a more compact load, while a deeper case may make more sense if you carry several accessories.
Consider leather finish and care expectations
These bags use full-grain leather, with different finishes and colors. One model is described as having a weathered, crazy-horse finish that changes in appearance with use, while another is described as developing a patina. Natural leather can have variation in its surface, so the exact grain pattern may differ from the product image.
Read water-resistance claims carefully
One product description specifies resistance to light rain, which is not the same as a waterproof construction. If you often walk in wet conditions, consider how you will protect the laptop and contents from heavier rain. Do not assume a leather exterior or a zipper alone makes a bag waterproof.
Check current listing details before ordering
Product specifications and availability can change. Confirm the current size, laptop compatibility, color, strap details, and availability on the product page before you buy. This is especially important for the brown 16-inch model, which is listed as unavailable in the supplied product information.
Frequently Asked Questions

The large black case is described with an adjustable strap, but its supplied details do not say that the strap is removable.

Are these leather briefcases waterproof?

Which option is best if I carry two computers or devices?
The vintage full-grain briefcase for most 15.6-inch laptops has two laptop sleeves, including one removable sleeve. That layout may help separate a laptop from a second device, though the case itself weighs 3.6 pounds.

Final Recommendation
For a large computer and a broad set of work essentials, the Masa Kawa large black briefcase is the most capacious choice in this group. If you prefer a lighter, slimmer case for a compact laptop, the brown 14-inch model is the clearest fit.

Whichever you choose, verify your laptop’s measurements and the bag’s current listing details before ordering.
