Up for sale is one of the newest offerings from Waterfield SF Bags in San Francisco: the Packable Backpack, in black. This basically is new and in mint condition. I took it out fo the wrapper and put some things in it, but did not use it. As you can see, it folds into itself in its own pocket, but unfolds without wrinkles. It's lightweight and durable. Presently on backorder from Waterfield. Retails for 9. Waterfield makes great products.
