Abstract
The invention is related to a golf club head including an internal subassembly defining an inner space and including a combination of a rigid, hollow and open internal shell made of a low-density material, and an impact-resistant sealing element co-operating with the shell to close off the inner space and having an inner wall for supporting the striking surface of the head. The internal shell is covered by an outer plastic casing at least partially covering the internal subassembly and forming the outer wall of the striking surface.
