A sport equipment for absorbing and dispersing, at least in part, an impact force, thereby reducing the impact force. The sport equipment can be a helmet having an outer shell, an inner shell, and a tensile sheet located between the outer and inner shells. The outer shell includes an interior side featuring a plurality of outer shell detents extending out therefrom. The inner shell includes an exterior side featuring a plurality of inner shell detents extending toward the outer shell. The tensile sheet is configured to dissipate and redirect, randomly directed impact force applied to the outer shell, to a tensile loading directed along a respective longitudinal axis of the tensile sheet. The outer and inner shells are in a spaced apart relationship with and movable to each other. The outer shell detents extend toward the inner shell.
