Some companies have bags that they loan out to employees who have to carry company products, literature etc. For example, apparel companies have A Saks - type suitcases that hold lots of samples and work materials that are meant to be left at the factory in Europe/Asia for reference. These bags fold back up when empty for the way back. Many Law firms provide rolling document bags for their staff on a need basis (i.e. when schlepping stuff to court/across town). And if your company provides a laptop, it usually comes with a laptop bag (although probably a crappy Staples one and not a nice one).

Depending on whether the item/line of work you're in is very specialized or not. It never hurts to ask.
