Viola backpack case: I know... it's for Magnus

[FarahShazam]

Summary: I want a slipcover for a viola case with backpack straps.

It's a 12inch viola case but if we can get one that will fit through a full size, that would be great. He's in 4th grade and they only rehearse once a week (so 6 times so far in total). He's got a nice little sound on such a crappy rental.

If not, that's okay too. Hope everyone is doing well.

Back packs tend to have backpack straps. Would one of them fit?
