This bag is great, most of the time I need a regular sling bag to carry around my asthma and diabetes supply along with my laptop or iPad. The best thing is this bag is a great size for most everyday things, but once in a while I need more like a jacket and a change of clothes, or when I go shopping. This bag transforms into a duffel so easy without having to take anything out I have in it already. I have serval sling bags but this tops them all. Someone mentioned that the bag fell off them from the shoulder straps not clicking in, and that’s mostly they didn’t install them correctly, I’ve not had this problem. I take this bag everywhere with me, gym, store, weekend trip, it’s now my everyday bag and I really like the comfortable way it feels even when loaded!
