I use this bag to carry my items with me on my morning bike commute to work. It is able to carry a full change of clothes, my tablet, and my surface pro laptop. All of that without even opening the straps to full capacity, so in reality I could carry much more. The main strap is easily adjustable while on or off of your body by pulling or releasing just one small tab. It has tons of little hidden zippers and pockets that you could stash smaller items in to keep organized. The touch I really liked, and I am not sure if many messenger bags come with this, was the additional strap that you can attach to hold the bag laterally so it does not slide off to one side while you are on your bike. Its a simple touch, but was really genius to me. I do wish that it came with the external pouch that attaches to the main strap to carry my cell phone. They sell it as a separate item. two of the straps that hang have reflective ends as well which stand out while I am riding at night. Overall it has just been a great bag to me for the past few months.
