Overall a very nice bag. I bought for a short business trip (3 days) and had plenty of space for everything. Looks good, has a lot of options for carrying and storage, reasonably priced and great for both the gym and short trips.-- Pros --* Flexibility (Carrying): This bag has a lot of options for both carrying. The backpack straps, shoulder strap and carrying handles were all used and appreciated (depending on how far I was walking or what else I was carrying. The straps all have compartments so they can be tucked away (see images).* Flexibility (Storage): There are a number of internal and external compartments, pouches, and a flex space which I used for dirty clothes. The flex space is particularly nice because it could be used as additional expansion if needed by flipping the lining outward (see pics). It's also great for keeping dirty items separate. The side zip pouches are nice to have but they are very small (more on that later).* Durability: Materials are all easy to clean, thick, and sturdy. The zippers are metal, move smoothly with no catching on lose fabric, and the ends sewn into the body so it is unlikely they will ever jump the track.* Appearance: Looks are subjective but I like the color of the light grey and the styling overall. In the listing the bag looks almost white but in person, the color is a bit darker (still a very, very light grey though).-- Cons --* Storage Space: As noted above, there are a lot of compartments. 6 exterior including- 4 side pouches that zip fully- 1 bottom pouch (when used as a backpack) that is adjustable in size and- 1 mesh stretch pouch on the top (when used as a backpack)The minor complaints I have are mainly that all of the zip pouches have very little space and don't stretch or expand much at all. You can't fit much more than some socks, deodorant (see pics), or a few cables/cords/chargers/etc.The mesh pouch on top (in backpack form) does not close or fasten in any way and when used as a backpack the opening is behind you and angled downward (see pics). This means it better be empty when you wear it as a backpack (otherwise it will be empty soon enough...).* Lose Stitching: More of a nit-pick here because overall the construction and quality is great but there were a few loose stiches here and there. Nothing major and easy to snip but one of them on the carrying strap didn't fully tie off so eventually it will unthread itself further. Easy fix for me and doesn't change my general satisfaction with the quality.
