It’s got everything a good work bag needs. A top handle for the short trips, a shoulder strap for longer walks, and a thin enough frame that it won’t weigh the rest of you down. You want to look like you’re going to work, not on a four day vacation and you’ve tried to pack everything in your carry on.
Plus the price is downright cheap. Under $50 for a simple leather-like brief. Which is pretty rare territory for real decent looking bag.
