Soundwear Protector Trombone

The shoulder straps can be stored neatly inside the bag. However, this feature puts those straps into harm's way once they are being used. The straps tear the fabric apart where they are attached to the "hull". This product simply cannot be used as a backbag. If you carry it by the handle, it's fine, but then you might just as well use the original case your trombone came in...
