Laterally supported filaments
A garment worn by a wearer has an impact absorbing material comprising arrays of various hexagonal or other deformable polygonal-shaped structures positioned between an exterior surface and an interior surface. When force is applied to the exterior surface, the structures of the impact absorbing materials deform (e.g., buckle) in a desired manner, reducing the force received by the interior surface.
