A protective helmet useful in sports (e.g., football) for protecting the head of a user includes an outer layer and an inner layer. The outer layer is connected to the inner layer by multiple connectors that are under tension along their longitudinal axis. The connectors absorb energy from the force of an impact by resisting further tension along their longitudinal axis and allow the outer layer and inner layer to move relative to each other. The helmet affords a reduction in the amount of force, including rotational force, from an impact that is transferred to the head of a user.
