I bought this bag from Amazon about 6 years ago, and it was the perfect solution for me when my FW12 came in. Holds my laptop, my iPad Pro 11” in its own sleeve, noise canceling headphones, all the cables and tools, and a USB mouse. I even carried around my Logi K400+ in its own sleeve as well, but I never needed it outside the house. Looks good, feels good. I got the green one. It didn’t come with zipper locks or a USB hub at the time, though.
