This is a backpack which also fits a double horn. It's different than the the other Bonna cases. It has a stiff fiberglass tray in the back, multiple storage pockets, and a few dividers to tuck a medium body double horn into the middle of it all. It doesn't have much padding over the top, it's a backpack. The padding comes from your own additional, or a protective bell cone. This case is probably not for your heirloom instrument, but more for your jobbing horn. It's light for bicycle or metro travel, it's very small for commercial air travel, and you can fit other items in it as well. A few pieces of soft clothing inside will only help protect everything.
A carbon- fiberglass bell protector cone is available separately, and is recommended for this case. Only the medium size bell cone fits well in this case, large is not ideal. Choose from the drop-down menu - we reserve a bell cone for the case.
Says Mr. Bonna...
The backpack bag with room for horn model MB fits one screw bell French horn.
It has been designed to make short traveling more practical. Besides the French horn, it is possible to fit one mute and some pieces of clothes. (We do not recommend filling the backpack bag to its maximum. It may damage the case and/or damage the instrument). If you need to travel with more clothes we have the “Travel Bag MB With Room for Detachable Horn” model.
Its possible to increase the size of the backpack by 5 cm using the expansion system. It also has two front pockets (for accessories) and the waist belt for a more comfortable weight distribution across your body. Several interior pockets and organizer show the attention to detail.
MB cases models have a new system that is adaptable for different types of french horns. The EVA parts and cushions have Velcro attachments, so they can be adapted in order to fit most sizes of double horns.
The case includes:
The back and lower sides of the case have a fiberglass shell for protection, while the front is padded nylon. An optional (recommended) fiberglass bell protection cone is available for extra protection during heavy travel.
