wherein said first density is less than 2.0 g/cm³ and said first young'"'"'s modulus is less than 40 Gpa;

wherein said second density is greater than 2.0 g/cm³ and said second young'"'"'s modulus is greater than 40 Gpa.

2. A golf club head, comprising:

a body comprising a striking face and a perimeter portion extending aft from said striking face;

wherein said perimeter portion comprises a sole located below said striking face;

wherein said perimeter portion comprises a topline located above said striking face;

wherein said body comprises a body cavity formed behind said striking face and within said perimeter portion;

wherein said striking face comprises a front surface, configured to strike a golf ball, and a rear surface opposite said front surface;

a badge affixed to said rear surface of said striking face;

wherein said badge comprises;

a first layer aft of said striking face, said first layer comprising a first density;

a second layer aft of said first layer, said second layer comprising a second density; and

a third layer aft of said first layer;

wherein said third layer comprises a third layer front surface located adjacent said second layer, said third layer font surface comprising a third layer cavity, wherein said second layer resides within said third layer cavity;

wherein said first density is less than 2.0 g/cm³;

wherein said second density is greater than 2.0 g/cm³.

3. The golf club head of claim 2, wherein said first layer comprises a first young'"'"'s modulus and said second layer comprises a second young'"'"'s modulus, wherein said first young'"'"'s modulus is less than 40 Gpa and wherein said second young'"'"'s modulus is greater than 40 Gpa.

4. The golf club head of claim 2, wherein said second layer comprises a second layer front surface, located adjacent said first layer, a second layer rear surface, located opposite said second layer front surface, a second layer top side surface located towards said topline, and a second layer sole side surface located towards said sole, said second layer sole side surface located opposite said second layer top side surface, wherein said second layer front surface abuts said first layer, wherein said second layer rear surface abuts said third layer, wherein said second layer top side surface abuts said third layer, and wherein said second layer bottom side surface abuts said third layer.

5. The golf club head of claim 2, wherein said first layer is viscoelastic.
