How it is built

A 2 m length of 50 mm woven polyester webbing on a side-squeeze buckle, adjustable across the whole length. It runs once around the girth of the case and takes tension off a strained closure.

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.
