  • a face having a ball striking surface, the face being defined by a plurality of face edges, the face comprising a face plate forming at least a portion of the ball striking surface and a cellular stiffening structure engaged with a rear surface of the face plate, the cellular stiffening structure providing increased stiffness to the face;

    a body connected to the face and extending rearward from the face edges to define an enclosed volume, the body having a heel side, a toe side, a crown, and a sole;

    a crown channel portion extending at least partially across the crown, the crown channel portion being defined by boundary edges, with the crown channel portion being recessed from the crown between the boundary edges of the crown channel portion; and

    a sole channel portion extending at least partially across the sole, the sole channel portion being defined by boundary edges, with the sole channel portion being recessed from the sole between the boundary edges of the sole channel portion,wherein the crown channel portion and the sole channel portion are spaced rearwardly from the face edges by a spacing portion,wherein the crown channel portion and the sole channel portion are configured such that at least some energy from an impact on the ball striking surface is transferred through the spacing portion and absorbed by at least one of the crown channel portion and the sole channel portion, causing the at least one of the crown channel portion and the sole channel portion to deform and to exert a response force on the face.
