An expandable backpack that also functions as a horn case, with a plethora of pockets and storage options! An updated version of the popular Marcus Bonna backpack bag with room for horn.

This backpack fits almost any detachable French horn, and is great for short trips. It will fit under nearly any airline seat.

Besides the instrument there is also room inside for a mute and some clothing. Pack everything you need for a weekend away in one carry-on! Additionally, there are two external front pockets providing more storage space, and one back pouch for sheet music or a laptop.

We do not recommend filling the backpack bag to its maximum. It may damage the case and/or damage the instrument. It's possible to increase the size of the backpack by 5 cm using the expanding zipper.

The waist belt provides a more comfortable weight distribution across your body.

The case includes:

• connectable straps

• 1 mouthpiece pouch for three mouthpieces

• 1 waist belt

• 1 identification tag

21.5" x 13.5" x 7.5"

We highly recommend you buy a Marcus Bonna bell protector to accompany this case.

Is this the right Marcus Bonna case for my horn?
