Just Right!
The material is sports wear - light, breezy and silky to the touch.
Pattern/Design came out as expected from the image, no errors and I tend to choose 1 size up so Medium - Large are my go to's.
Fit well with spare room to fill.
Worth the money.

Well Padded, good zipper compartments
Size: 14 Inch, Style: 1-pack
This is a really basic case but it fits and looks amazingly great. This one fit my 15" laptop without any issues. The padded interior provides a bit of protection. The zipper side pockets are perfect. I use this to visit different campuses and holds just enough for field work. The price is right and compared to the name bags, this is a great bargain for a quality case.

Great no-frills bag. Slim and compact, but still holds plenty.
Size: 17.3 Inch, Style: 1-pack
I needed a case for my new HP Pavilion 17" laptop.
I didn't need anything fancy or with all kinds of special features. I didn't need one with a lot of extra storage space beyond what was required for the laptop, its power adapter and cord, and a small mouse. And above all I didn't want one with a large, bulky profile, one that would feel like I was carrying--or rolling--a small suitcase.
Turns out this AmazonBasics bag was just what I was looking for.
It is indeed slim and compact, and it's lightweight to boot (only weighing about 1 lb.). And even when it's filled to the brim and weighs a good bit more, it STILL looks slim and compact.
For its economical price point, it is constructed very well, and thus should be quite durable for light to moderate use. The stitching is very tight and clean, with even strong, "zipper-stay" stitching being included on this inexpensive bag. The zippers themselves (which I tend to be picky about) are of very good quality, and open and close without much effort. The zipper pulls are ample in size and weight, and are very strong and sturdy. In other words, they're NOT cheap.
I appreciate the case's simple yet thoughtful design. I especially like the single, large, zippered pocket on the front "face" of the bag, where you can easily and conveniently keep oft-used items such as your phone, keys, power bank, and so forth. Too many laptop bags' outside pockets are unzippered, which I find both impractical and unsafe.
The AmazonBasics bag holds my laptop snugly and securely, yet I can still manage to squeeze in extra padding (about 3/8" thick and 1.5" wide) all around its perimeter. I do this because the case provides only the most minimal of padding throughout. (Mind you, I wouldn't have expected sufficiently thick padding on a bargain bag such as this one, but it's worth bringing attention to nonetheless.) The upshot here is that, as well constructed as this case is, it's not designed to protect our laptops from accidental drops onto hard surfaces. There simply isn't enough shock-absorbing padding.
But frankly I'm not that worried about accidental drops. Rather, for my most pressing general needs--storing or transporting my laptop and keeping it free from dust, scratches, dents and the like--this AmazonBasics bag really fits the bill. It's easy to carry, and it's easy (and quick) to access your laptop.
I'm VERY happy with it, would buy another one without hesitation, and I highly recommend it!
Finally, my goal as a reviewer is always to try and help others make better informed decisions about potential Amazon products they may be considering. Toward that end, I hope in some small way that you may have found this helpful. Thanks for reading my review. Best of luck with your shopping!

Love this bag.
Size: 15.6 Inch, Style: 1-pack
I love this bag. It was affordable, and it has plenty of compartments to store my cords and portable drives. It is fun to be able to get work done at coffee shops and theme parks etc...
