Zicac Men's Vintage Canvas Multifunction Travel Satchel - Amazon Review
I like the look of it and it holds a surprising amount of stuff (and everything that I need to take with me when I go out), but one of the clasps that holds the strap broke after two months of casual use. I've wrapped a bunch of masking tape around it so I can resume wearing the purse without it falling off, but it does detract from its appearance.
Edit: And not long after writing this review, the second clasp broke, as well. Dropped the rating from 4 stars to 3.
