Yes, and it's a great size for this purpose (commuting). Today I had it packed with a spare tube, tools, an electric pump (I'm lazy), a case for my glasses, a clean T-shirt and undies. I could probably fit a few other small items if needed, but this is all I bring to work.

The front rack is really what ties this build together for me. I have to schlep my laptop back and forth every day. I've used a rear rack and pannier, but I wanted something different. A backpack works but feels cumbersome. The Porteur rack just happened to be almost the exact dimensions of the padded laptop sleeve I've been using for 15 years.
