My guess would be "no". It looks like the bottom area where the guitar sits is a fixed width that does not collapse or shorten, and that part looks bigger than the width of the outer pocket. It might be close, though. Notice that the web link does not provide dimensions for the collapsed configuration. I always have a second bag for a song binder, water bottle, and other miscellaneous things like an instrument stand when going out for a jam or a gig. It is difficult to get away with carrying only one thing. My goal is to carry what is needed in one trip.
