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.
