Gard 9-MSK Gigbag f. Trumpet/Flgh.

I use this just about every time I leave the house. Plenty of room for Trumpet, Flugel and all the mutes you'd ever need.

It's pretty hard wearing, the material is scratch resistant and the case case has saved my horns from a knock or two while commuting.

It's not the smallest bag in the world but having the option of being able to add a third trumpet to the bag was a deal breaker for me.
I've had the following combinations in mine with no bother at all:
Bb Trumpet/Flugel/4-5 Mutes
Bb Trumpet/Flugel/Cornet + 1-2 mutes
Bb Trumpet/Flugel/Eb Trumpet

I have played the Trumpet since 1959 and only acquired a Flugelhorn just over a year ago, for months I travelled around with two instrument cases, I needed a solution.

The Gard 9-MSK Gigbag is designed to hold two Trumpets on one side and a Flugelhorn on the other, it is especially kind to your instruments with special grey foam suspension holders for the instruments.

The versatility of the Gigbag appealed to me, my requirement was to put my Flugelhorn on one side, but on the other, the music stand for my iPad fits neatly on the bottom, with my mutes, all in the place for a second Trumpet, on top of the nice foam protector provided goes my own Trumpet.
