According to the Messenger Bag manufacturers list, Zo Bags are still available by mail order from San Francisco. However, the Zo link leads you to a handwritten note suggesting that bags will only be available for sale, from time to time, via ebay. At the moment, I know that there are many great contemporary messenger bag companies (Lemolo, Bailey Works, Re-Load Baggage, Zugster, for starters). I also know that there is a bit of a Zo backlash because of availability issues (and after-market boutique status?). Nevertheless, I remain fascinated by the 1997 iteration of Zo bags when the entire product line, plus accessories, could be perused on a single sheet of paper (with lots of buffering white space). Navigating the Re-Load site, for example, w/its “music series” dj bags and complex size/style/sale options, makes me long for the visual simplicity, and direct address (see handwritten note), of my 1997 Zo promotional mimeograph.
Now regretting that I waited twelve years to mail in my order for a Zo Gravey Dog messenger bag in black cordura (another synthetic exception). I used to own a small red Zo bag but it lacked the sway strap which kept it from lurching from side to side during vigorous pedaling. I could never locate a replacement strap so I ended up passing the bag along to a friend.
