Low-cost Backpacks are the divas in the luggage world. One may possibly work as a daypack yet won't carry enough to get a three-day business trip. One more is perfect for work but far too small or formal for that gym. I have a modern pack that nicely matches one laptop but bliss forbid I need it to allow a water bottle, heavy papers or--yeesh--a second notebook, and it's like I've questioned it to pick me way up from the airport on a Sunday night
