Waist belt for rux 70

When using backpack straps the hard edges on the 70 dig into your lower back aggressivly if the bag is not full, designing a minimilast waistbelt that is of the same style as whats on coventional 70L hiking packs would be very nice for backcountry transport. For attachment the back of the belt could have a C shape attchment frame (soft) to clip into three sides of the utility rails at the bottom of the bag would make the bag carry substiantly better with heavy loads or when the bag is not full. By making the conection seystem foldable it could be easily folded and put inside the bag, cliped to the top when in transported on veichles
