This is a great bag which provides a lot of flexibility and is suitable for all occasions. Comfortably fits two of my trumpet, flugel and cornet at once, and you can just squeeze in a stand and/or mutes as well (not all of these when the flugel is in).
My only niggle is that the side pocket is not quite big enough to fit music, though there's not a lot of scope to have made it bigger and you can fit a music folder inside next to one of the instruments.
