A backpack attachment system for a hardshell musical instrument carrying case includes rings that are permanently attached to the exterior of the case, thereby allowing quick access for using a backpack type strap or straps for carrying the case. The strap set itself is optionally removable, but the attachment rings are not, being permanently mounted to the case, using, for example, rivets, screws, snaps or equivalent means.
