In one example, a golf club head includes a body portion, a first interior cavity portion, and a face portion, which includes a back surface with a face perimeter portion, a ridge portion extending from the face perimeter portion, and a wall portion coupled to the ridge portion and extending outward from the ridge portion to define a second interior cavity portion in the body portion. The golf club head further includes a first filler material and a second filler material. The first interior cavity portion is at least partially filled with the first filler material, and the second interior cavity portion is at least partially filled with the second filler material. Other examples and embodiments may be described and claimed. ## Claims ### Claim 1 A golf club head comprising: a hollow body portion; a face portion coupled to a front portion of the hollow body portion to define a first interior cavity portion in the hollow body portion, the face portion comprising: a front surface; a back surface opposite the front surface; a face perimeter portion having a perimeter edge defined by a face toe edge, a face heel edge, a face top edge, and a face sole edge; a ridge portion extending from a portion of the face perimeter portion proximate to the face sole edge toward the face top edge; and a wall portion coupled to the ridge portion and extending outward from the ridge portion to define a second interior cavity portion in the hollow body portion; a first filler material; and a second filler material, wherein the first interior cavity portion is at least partially filled with the first filler material, and wherein the second interior cavity portion is at least partially filled with the second filler material. ### Claim 2 (depends on 1) A golf club head as defined in claim 1, wherein the first filler material and the second filler material have at least one different physical property. ### Claim 3 (depends on 1) A golf club head as defined in claim 1, wherein the first filler material and the second filler material have different coefficients of restitution. ### Claim 4 (depends on 1) A golf club head as defined in claim 1, wherein the first filler material and the second filler material have different vibration dampening properties. ### Claim 5 (depends on 1) A golf club head as defined in claim 1, wherein the wall portion includes a wall portion height, and wherein the wall portion height increases in a top-to-sole direction. ### Claim 6 (depends on 1) A golf club head as defined in claim 1, wherein the first interior cavity portion and the second interior cavity portion are at least partially filled with the first filler material and the second filler material respectively from a port on the hollow body portion connected to the first interior cavity portion. ### Claim 7 (depends on 1) A golf club head as defined in claim 1, wherein the face portion comprises a back groove portion between the ridge portion and the face perimeter portion. ### Claim 8 A golf club head comprising: a hollow body portion having a first interior cavity portion and a face portion, the face portion comprising: a front surface; a back surface opposite the front surface; a face perimeter portion having a perimeter edge defined by a face toe edge, a face heel edge, a face top edge, and a face sole edge; a face recess portion on the back surface located within the face perimeter portion; a back groove in the face recess portion; a ridge portion extending from a portion of the face perimeter portion proximate to the face sole edge into the face recess portion; and a wall portion coupled to the ridge portion and extending outward from the ridge portion; a first filler material; and a second filler material, wherein a volume bound by the face recess portion, the ridge portion, and the wall portion defines a second interior cavity portion, wherein the first interior cavity portion is at least partially filled with the first filler material, and wherein the second interior cavity portion is at least partially filled with the second filler material. ### Claim 9 (depends on 8) A golf club head as defined in claim 8, wherein the ridge portion has a circular shape. ### Claim 10 (depends on 8) A golf club head as defined in claim 8, wherein the ridge portion comprises an inner ridge portion, an outer ridge portion, and a ridge portion top between the inner ridge portion and the outer ridge portion, and wherein the wall portion is attached to the ridge portion top. ### Claim 11 (depends on 8) A golf club head as defined in claim 8, wherein the wall portion includes a wall portion height, and wherein the wall portion height decreases in a sole-to-top direction. ### Claim 12 (depends on 8) A golf club head as defined in claim 8, wherein the back groove comprises a first back groove portion between the ridge portion and the face toe edge, a second back groove portion between the ridge portion and the face top edge, and a third back groove portion between the ridge portion and the face heel edge. ### Claim 13 (depends on 8) A golf club head as defined in claim 8, wherein the back groove is at least partially filled with the first filler material. ### Claim 14 (depends on 8) A golf club head as defined in claim 8, wherein a thickness of the face portion at the ridge portion is a same as or substantially a same as a thickness of the face portion at or proximate to the face perimeter portion. ### Claim 15 A golf club head comprising: a hollow body portion being including a first interior cavity portion at least partially filled with a first filler material, the hollow body portion having a front portion with a front opening; a second filler material; a face portion coupled to the front portion to close the front opening, the face portion comprising: a front surface; a back surface opposite the front surface; a face perimeter portion having a perimeter edge defined by a face toe edge, a face heel edge, a face top edge, and a face sole edge; a face recess portion on the back surface and having a recess perimeter portion at least partially surrounded by the face perimeter portion; and a plurality of back groove portions in the face recess portion, the plurality of back groove portions extending proximate to the recess perimeter portion along at least 50% of the recess perimeter portion, a ridge portion extending from a portion of the face perimeter portion proximate to the face sole edge into the face recess portion; and a wall portion coupled to the ridge portion and extending outward from the ridge portion to define a second interior cavity portion in the hollow body portion; wherein the second interior cavity portion is at least partially filled with the second filler material, and wherein a coefficient of restitution of the first filler material is different from a coefficient of restitution of the second filler material. ### Claim 16 (depends on 15) A golf club head as defined in claim 15, wherein the plurality of back groove portions at least partially surround the ridge portion. ### Claim 17 (depends on 15) A golf club head as defined in claim 15, wherein the ridge portion forms a continuous loop on the back surface of the face portion. ### Claim 18 (depends on 15) A golf club head as defined in claim 15, wherein the wall portion includes a wall portion height, and wherein the wall portion height decreases in a sole-to-top direction. ### Claim 19 (depends on 15) A golf club head as defined in claim 15, wherein the plurality of back groove portions comprise a first back groove portion between the ridge portion and the face toe edge, a second back groove portion between the ridge portion and the face top edge, and a third back groove portion between the ridge portion and the face heel edge. ### Claim 20 (depends on 15) A golf club head as defined in claim 15, wherein the plurality of back groove portions are at least partially filled with the first filler material.
