Most of the time, I carry the Amy Kestenberg Tamitha nylon backpack with gunmetal hardware. It's because it will accommodate my work laptop, notebook and other essentials. It also has a back slip pocket and a secure lock on the zipper. I liked it so much that when Nordstrom rack offered the bag in grey $29 I grabbed it. I also grabbed a spare in case this one dies. It also makes a great overnight bag. I also carry the Coach market tote. I pair my backpack with a very small crossbody or WOC. That way my badge, hand sanitizer transit card, and keys are within easy reach.
