Abstract
Protective gear such as a helmet includes multiple shell layers connected using one or more concertinaed structures. The concertinaed structures allow the shell layers greater flexibility to move relative to each other when mechanical forces are imparted onto the outer shell layer. When energy and impact transformer layers are disposed between the shell layers, the concertinaed structures may also allow improvement function of the energy and impact transformer layers.
