I purchased this a few years ago, but I've only used it two or three times outside and have kept it in storage without putting any instruments in it. The shoulder strap is not removable, but the length can be adjusted over a wide range. You can also insert A4-sized sheet music into the pocket on the back. The two pockets inside can hold things like cork grease, a cleaning swab, or a mouthpiece. Please forgive the slight stains on the surface from storage, although they are not very noticeable.
