The black 15.6" Messenger Laptop Bag from Microsoft is a budget-priced shoulder bag that still maintains features that make it comparable in function to higher priced alternatives.
Made from tough polyester, the bag is designed with a stylish red accent stripe to give it a measure of fashion but it doesn't stop there. Your 15.6" laptop (39.6 cm) is protected in a padded sleeve that is equipment-friendly and won't damage the delicate surface of the screen. To support the computer, there is a digital accessory pocket that will hold cables, batteries, adapters, plugs and similar items. Two file pockets handle your documents and folders.
If you're traveling with a rolling luggage cart, just slip the Messenger over the handle using the included trolley sleeve for easier portability. The shoulder straps and carry handle are also padded for additional comfort. At a reasonable price and backed by a 5-year warranty, this bag is an affordable mix of function and style.
