mine carries almost all my small (harmonica) gear:
16-hole chromatic Hohner Super 64 Performance in original case, 7 diatonics in a flex case, Hohner service kit, 5 ml lubricant bottle, 80 ml mouthpiece cleaner bottle, cleaning cloths, 0,60 l water bottle, Nux Mightylight mini amp + adaptor, Audix Fireball-V microphone + accessoires, 3 audio cables (2,5 m, 3 m, 6 m), music stand lights + spare batteries, magnets, clamps, cable straps, 2 sheet music folders, 3 song books, notepad, pencil, electronic metronome, in-ear hearing protection, 4 egg shakers ...
in one of the numerous compartments, sleeves and pockets.
the bag is very well built and suitable to carry a full load with a comfortable fit. if needed i can detach the 'flute' bag to carry my chromatic and microphone (my most expensive items) on my body during breaks.
this level of quality and performance for that price = a bargain.
