1. A golf club head comprising:

  • a body comprising a sole, a crown, a body heel end, a body toe end, a body front end, and a body rear end; and

    a trench feature at a body section of the body,the body section comprising one of the sole or the crown;

    wherein;

    the trench feature comprises;

    a trench cap having a specific gravity of less than 2, and a hardness of approximately less than 90 Shore A;

    an inner trench section comprising a trench and an inner section wall bounding the trench;

    a reinforcement structure protruded from the body section and bounding the inner trench section;

    whereinthe reinforcement structure is separated from the trench cap by the inner section wall;

    the reinforcement structure comprises;

    a reinforcement inner perimeter adjacent to the inner trench section;

    a reinforcement outer perimeter opposite the reinforcement inner perimeter; and

    a reinforcement peak protruded between the reinforcement inner perimeter and the reinforcement outer perimeter;

    the body section comprises;

    a body section exterior surface defining an exterior body contour of the body section, wherein the body section exterior surface is discontinuous at the trench feature and extrapolates the discontinuous segment at the trench feature; and

    a minimum outer thickness, located outside the reinforcement outer perimeter, and measured orthogonal to the exterior body contour;

    the trench feature further comprises;

    a reinforcement thickness measured, orthogonal to the exterior body contour, from the reinforcement peak to the exterior body contour; and

    a reinforcement girth measured, orthogonal to the reinforcement thickness, between the reinforcement inner perimeter and the reinforcement outer perimeter;

    the reinforcement structure protrudes past the minimum outer thickness into the body;

    the reinforcement structure protrudes past the inner trench section into the body; and

    the reinforcement girth is at least approximately 1.5 times greater than the minimum outer thickness.
