How it is built

Two 50 mm polyester straps joined at a central four-way plate so they run around both the girth and the length of the case. The plate stops either strap creeping toward a corner, which is what a single strap on a polished shell tends to do.

Suits these shells

Hard shell, polycarbonate: Flexes under load and springs back. Takes surface scuffing more than cracking.
Hard shell, ABS: Stiffer and more brittle than polycarbonate. Corners are the usual failure point.
Aluminium frame: A full cover fits badly over the frame lip. Corner and edge guards suit these better.
Soft side, fabric: Absorbs impact but scuffs and tears. Zippers and handles take the strain.
