Marcus Bonna Mute Bag - the best on the market as with all his goods. Heavy duty steel clips ensure that your mute will stay attached to your case. Inquire about colors in stock.
This is exactly the kind of mute bag I was looking for. It's spacious enough for my standard mute but I can tell it will easily accommodate an upgrade. It works perfectly with the Marcus Bonna horn case so I can carry everything hands-free.
