A golf club head includes a metal portion adhered to a polymeric portion to define a closed internal volume. The polymeric portion defines a bore that is configured to receive and to selectively retain an elongate weight. The bore is aligned on a longitudinal axis that intersects the face. The polymeric portion includes a polymeric wall extending within the closed internal volume and transversely outward from a sidewall that defines the bore. The polymeric wall is adhered to the metal portion of the golf club head and is operative to both reinforce the sidewall and to transfer impact stresses from the sidewall to the metal portion of the golf club head.
