Just so so okay... not too stylish but is functional, priced a bit high for basic backpack
Color: Black, Size: 15.6 Inch
This is simply a basic backpack that is comparable to below $30 laptop backpacks out there, the only thing really that is stylish design in regard to color is the inside fabric color. I've gotten my wife other laptop bags that actually have more style on the outside and yet cost less. Very very basic packpack, just a tad bit overpriced. It actually looks like a middle school backpack if you think about it's plain design and those you can find under $25, the laptop compartment is just 20% better than than school backpacks.
