I bought the Bellroy Venture Sling 9L (large crossbody bag) - Nightsky color off Amazon (the link if to the Bellroy website, it's the exact same price as Amazon as of right now) about a month ago. Every weekday I wear it to and from work, maybe 30 minutes of very light wear daily. I also refrain from hard using items if I can, including this bag, so that they might last longer with less visible wear. This bag still looks like I took it out of the packaging last night, as if never used.

It's a significant step up in quality (and cost) of the rough canvas messenger bag I bought a year or two previously. That messenger bag had more room due to height but I didn't like how it sagged so much. I also didn't care for the strap on the messenger bag at all. The Bellroy crossbody 9L bag is working nicely and the overall impression is that as long as nothing crazy happens, I could very easily use this bag for decades to come.
