I love these bags and have several. A small microfiber that I have been using every day for a couple of years. A medium one for some trips. A large mesh, and a leather mini. You can wear them on either shoulder. I have see them at stores like The Walking Store or some luggage shops at outlet malls. Cheapest sellers are ebay and Sierra Trading Post. I sometimes see men wearing them, but usually the larger ones. I bought one of the medium Tech models for a guy who uses it for the gym.
