What to know before buying

Listing details to confirm

Listing details are inconsistent: the title says 13.5L while product details and feature text say 14.5 litres, and the listed dimensions of 42.5 x 32 x 5.5 centimetres differ from feature text stating 40 x 30 x 9 cm. The maximum laptop size is stated as 15.6 inches, but check your device's dimensions against the bag before buying. Water resistance is a coating claim, not a waterproof rating.

Only aggregate rating information is supplied, not customer comments. Ratings lean positive overall, but the distribution also includes a smaller one-star share and a notable three-star share, so it does not establish specific strengths or explain dissatisfaction. For buyers, treat this as limited satisfaction context rather than evidence about durability, comfort or fit.

Frequently asked questions

What size laptop does the listing say this briefcase fits?

It states compatibility with devices up to 15.6 inches. Check your laptop's actual dimensions against the bag before buying, as screen size alone does not establish fit.

Is the shoulder strap removable?

Yes. The listing describes an adjustable, removable shoulder strap as well as carry handles.

Is the briefcase waterproof?

The manufacturer describes a protective coating that makes it water resistant. No waterproof rating is supplied.

How much can the bag hold?

The title says 13.5L, while product details and feature text state 14.5 litres. The listing does not settle the discrepancy.
