OBO's ROBO chest protector is made of high density foam that covers key body areas. The heart area has an additional 16 mm high density polyethylene foam pad. The unique two section design allows the lower section to wrap tightly around the chest and ribs and allows the upper section to protect the clavicles and shoulders. Elasticated gussets provide complete mobility. When the player moves their arms and shoulders, the upper section closely follows the players body movement while the lower section stays firmly in place.
