This armor is mostly cast fiberglass, but the chest plate is a rubber stunt plate. This was used during filming. It has some scratches, scuffs, and chips. It has seen some battle. Nice. It has 2 piece articulated shoulder armor and cool braided wrap on the shoulder straps. This was designed by Colleen Atwood the Academy Award winner in 2003 and 2006 for best costume design. It is adjustable and would fit most larger gorillas (it was designed to be worn over a large gorilla muscle suit and other armor).
